it usually took place on ocean liners... 111 00:05:50,500 --> 00:05:52,009 But it was slow, crucially, it was slow. 112 00:05:52,033 --> 00:05:53,942 {\an1}It took it could take up to up to a week or

First World War 116 00:06:01,266 --> 00:06:04,333 supercharged aircraft development... 117 00:06:04,366 --> 00:06:07,500 {\an1}but passenger planes capable of crossing the Atlantic 118 00:06:07,533 --> 00:06:11,466 were still years from becoming a reality. 119 00:06:11,500 --> 00:06:15,533 {\an1}Instead, the focus fell on a different type of aircraft... 120 00:06:15,566 --> 00:06:17,933 One that had proven its long-range potential 121 00:06:17,966 --> 00:06:21,233 during the war. 122 00:06:21,266 --> 00:06:26,033 {\an1}-The Zeppelins were created to be used in military maneuvers. 123 00:06:26,066 --> 00:06:30,100 {\an1}Zeppelins were used by the Germans to bomb Britain 124 00:06:30,133 --> 00:06:35,233 {\an1}to drop bombs on citizens and the cities beneath them. 125 00:06:35,266

128 00:06:42,600 --> 00:06:46,966 {\an1}that would carry passengers, not bombs. 129 00:06:47,000 --> 00:06:50,700 {\an1}But the post-war Treaty of Versailles kept the Germans, 130 00:06:50,733 --> 00:06:55,433 experts in the field, sitting on the sidelines. 131 00:06:55,466 --> 00:06:57,800 {\an1}-Immediately after World War I, 132 00:06:57,833 --> 00:07:03,300 {\an1}the allies tried very diligently to stop Germany from rearming. 133 00:07:03,333 --> 00:07:07,233 {\an1}And that meant size of Army, that meant Navy, 134 00:07:07,266 --> 00:07:09,166 {\an1}and that meant aircraft. 135

here. 140 00:07:25,400 --> 00:07:27,100 {\an1}They go to the Americans and say, 141 00:07:27,133 --> 00:07:29,533 "If we build you this incredible airship, 142 00:07:29,566 --> 00:07:32,100 will you allow us to keep our factory running?" 143 00:07:32,133 --> 00:07:34,466 And the Americans go for this deal. 144 00:07:34,500 --> 00:07:36,800 {\an1}-So the Zeppelin Company clearly took advantage 145 00:07:36,833 --> 00:07:40,266 {\an1}of the immediate allowance of continued production 146 00:07:40,300 --> 00:07:45,266 {\an1}so that they could continue developing, continue perfecting, 147 00:07:45,300 --> 00:07:49,266 and basically restart their operation. 148 00:07:49,300 --> 00:07:53,133 {\an1}-When the restrictions were finally relaxed in 1926, 149 00:07:53,166 --> 00:07:55,300 Zeppelin immediately started production 150 00:07:55,333 --> 00:07:59,700 of its own airship, called the Graf Zeppelin. 151 00:07:59,733 --> 00:07:59,733 - The - Graf Zeppelin 152 00:07:59,733 -->

This is what Hugo Eckener wanted. 169 00:08:44,033 --> 00:08:46,500 {\an1}He wanted something that the public would look up to... 170 00:08:46,533 --> 00:08:49,566 {\an1}literally look up to... And be wowed. 171 00:08:49,600 --> 00:08:50,809 People were still afraid of this. 172 00:08:50,833 --> 00:08:53,000 {\an1}I mean, this is a really terrifying idea 173 00:08:53,033 --> 00:08:54,233 to be up in the sky. 174 00:08:54,266 --> 00:08:56,733 {\an1}What happens if you lose power? Can you crash? 175 00:08:56,766 --> 00:08:58,700 {\an1}I mean most people have never even been up 176 00:08:58,733 --> 00:09:00,166 in the air at this point at all. 177 00:09:00,200 --> 00:09:03,133 {\an1}So what he does is he takes the thing around the world 178 00:09:03,166 --> 00:09:05,600 and does a series of, basically, 179 00:09:05,633 --> 00:09:09,333 flights that show that it's viable. 180 00:09:09,366 --> 00:09:11,333 {\an1}-And that is, of course, what catapults Eckener 181 00:09:11,366 --> 00:09:13,366 to this position of enormous fame, 182 00:09:13,400 --> 00:09:15,233 is that he becomes a representation 183 00:09:15,266 --> 00:09:17,300 of this new age of dashing pilots. 184 00:09:17,333 --> 00:09:19,800 {\an1}They are the kind of knights of the sky. 185 00:09:19,833 --> 00:09:22,733 {\an1}-After Hugo Eckener had done his miraculous 186 00:09:22,766 --> 00:09:25,033 {\an1}'round the world trip, companies all around 187 00:09:25,066 --> 00:09:27,500 the world wanted to invest in airships 188 00:09:27,533 --> 00:09:30,966 and wanted Zeppelin to make them. 189 00:09:31,000 --> 00:09:33,233 {\an1}-After Zeppelin had successfully demonstrated 190 00:09:33,266 --> 00:09:36,066 {\an1}the airship's potential, Eckener... 191 00:09:36,100 --> 00:09:37,700 {\an1}determined to be at the forefront 192 00:09:37,733 --> 00:09:39,466 {\an1}of global air travel... 193 00:09:39,500 --> 00:09:42,666 Developed an ambitious plan. 194 00:09:42,700 --> 00:09:44,633 {\an1}His company would build an airship 195 00:09:44,666 --> 00:09:46,010 even bigger than the 196 00:09:46,034 --> 00:09:47,400 Graf Zeppelin. 197 00:09:47,433 --> 00:09:50,266 It would be called the Hindenburg. 198 00:09:50,300 --> 00:09:51,600 {\an1}-This was Germany saying, 199 00:09:51,633 --> 00:09:53,500 {\an1}"We're still a key player in the world, 200 00:09:53,533 --> 00:09:56,966 and we can do these incredible engineering feats." 201 00:09:57,000 --> 00:09:58,294 {\an1}-The 202 00:09:57,000 --> 00:09:59,633 is developed to show 203 00:09:58,318 --> 00:09:59,666 Hindenburg 204 00:09:59,666 --> 00:10:02,766 {\an1}that we can actually fly people long distances, 205 00:10:02,800 --> 00:10:04,833 pay for it through ticket revenues, 206 00:10:04,866 --> 00:10:08,033 {\an1}and he's effectively creating an airline industry 207 00:10:08,066 --> 00:10:12,066 where one had never existed before. 208 00:10:12,100 --> 00:10:17,666 -On March 4, 1936, 14 months before the disaster, 209 00:10:17,700 --> 00:10:20,033 {\an1}the Hindenburg  was ready to take to the skies 210 00:10:20,066 --> 00:10:22,466 {\an1}for the very first time. 211 00:10:22,500 --> 00:10:25,500 But no one... Not even its engineers... 212 00:10:25,533 --> 00:10:30,466 {\an1}knew how something so large would behave once airborne. 213 00:10:30,500 --> 00:10:33,066 {\an1}-Despite the fact that the Zeppelin Company 214 00:10:33,100 --> 00:10:36,033 {\an1}had had 25 years of success, 215 00:10:36,066 --> 00:10:38,510 - the - Hindenburg pushed things much, 216 00:10:38,566 --> 00:10:41,366 {\an1}much farther than it had ever been done before. 217 00:10:41,400 --> 00:10:45,133 {\an1}-It was so much bigger than any airship that had come before. 218 00:10:45,166 --> 00:10:48,400 {\an1}And in engineering, when you start scaling things up, 219 00:10:48,433 --> 00:10:51,100 {\an1}you do start entering problems. 220 00:10:51,133 --> 00:10:53,833 {\an1}Because of the vast size of the Hindenburg, 221 00:10:53,866 --> 00:10:56,333 {\an1}they really didn't know how it was going to fly 222 00:10:56,366 --> 00:10:57,966 {\an1}until they'd already built it 223 00:10:58,000 --> 00:11:01,500 and put it up for its first test flight. 224 00:11:01,533 --> 00:11:03,166 {\an1}-We're putting something up in the air 225 00:11:03,200 --> 00:11:07,066 {\an1}that has some seven acres of aeronautical cloth. 226 00:11:07,100 --> 00:11:12,100 {\an1}The vast forces that are on it are inconceivable. 227 00:11:12,133 --> 00:11:15,766 {\an1}So how it's going to behave is not known 228 00:11:15,800 --> 00:11:17,133 {\an1}and it makes you wonder 229 00:11:17,166 --> 00:11:21,366 {\an1}if it wasn't just too big in the first place. 230 00:11:21,400 --> 00:11:23,410 {\an1}-The 231 00:11:21,400 --> 00:11:25,466 first flight lasted more than three hours. 232 00:11:23,434 --> 00:11:25,500 {\an1}Hindenburg's 233 00:11:25,500 --> 00:11:28,566 {\an1}But the test flights were limited and inadequate, 234 00:11:28,600 --> 00:11:31,933 {\an1}while critical safety checks were overlooked. 235 00:11:31,966 --> 00:11:36,666 {\an1}Zeppelin missed a possible chance to find and fix problems. 236 00:11:36,700 --> 00:11:39,833 {\an1}-To establish that a type of aircraft is safe, 237 00:11:39,866 --> 00:11:42,700 {\an1}requires numerous tests: 238 00:11:42,733 --> 00:11:45,533 turning ability, stopping ability, 239 00:11:45,566 --> 00:11:50,700 {\an1}ability to control altitude in flight, flight test crashes, 240 00:11:50,733 --> 00:11:53,500 how to have emergency evacuations... 241 00:11:53,533 --> 00:11:55,966 So many things that ought to be in place. 242 00:11:56,000 --> 00:11:57,766 {\an1}Many of these weren't. 243 00:11:57,800 --> 00:12:00,633 {\an1}-They did seven test flights to make sure 244 00:12:00,666 --> 00:12:02,500 {\an1}that it would actually be able to get airborne 245 00:12:02,533 --> 00:12:05,000 and do the job that they thought it could do. 246 00:12:05,033 --> 00:12:06,966 {\an1}Of these seven test flights, 247 00:12:07,000 --> 00:12:10,533 all of them were done above land in Germany. 248 00:12:10,566 --> 00:12:12,000 {\an1}None of them were testing 249 00:12:12,033 --> 00:12:14,466 {\an1}actually what they were hoping to do with the Hindenburg, 250 00:12:14,500 --> 00:12:17,533 which was to fly it across the Atlantic. 251 00:12:17,566 --> 00:12:19,866 {\an1}-It is strange, isn't it, that flight tests 252 00:12:19,900 --> 00:12:22,300 {\an1}for an over-ocean aircraft 253 00:12:22,333 --> 00:12:25,066 wouldn't include an over-ocean flight trial. 254 00:12:25,100 --> 00:12:28,300 {\an1}But this was the case back in the 1930s. 255 00:12:28,333 --> 00:12:30,633 Remember, aeronautics is really new. 256 00:12:30,666 --> 00:12:32,966 {\an1}There's so many things that are unknown. 257 00:12:33,000 --> 00:12:36,900 And this vehicle is so much larger 258 00:12:36,933 --> 00:12:39,866 {\an1}than what had ever been tried before. 259 00:12:39,900 --> 00:12:42,233 {\an1}-After just a handful of test flights... 260 00:12:42,266 --> 00:12:44,233 {\an1}all performed over land... 261 00:12:44,266 --> 00:12:48,500 The first passengers were welcomed onboard. 262 00:12:48,533 --> 00:12:52,300 {\an1}And then the Hindenburg  set off on an epic 6,000-mile, 263 00:12:52,333 --> 00:12:55,266 four-day flight across the Atlantic, 264 00:12:55,300 --> 00:12:58,866 {\an1}from Germany to Brazil. 265 00:12:58,900 --> 00:13:00,833 -The Hindenburg, when it first took off, 266 00:13:00,866 --> 00:13:03,333 was completely an experimental aircraft 267 00:13:03,366 --> 00:13:06,233 {\an1}and probably had no business taking passengers 268 00:13:06,266 --> 00:13:08,166 for a long time. 269 00:13:08,200 --> 00:13:11,166 {\an1}As an experimental aircraft, there were certainly issues 270 00:13:11,200 --> 00:13:12,900 {\an1}that had to be worked out 271 00:13:12,933 --> 00:13:17,600 {\an1}and it's clear from memos and letters back and forth 272 00:13:17,633 --> 00:13:21,600 {\an1}in hasty fashion that they were devastating issues 273 00:13:21,633 --> 00:13:24,333 {\an1}that had to be resolved quickly. 274 00:13:24,366 --> 00:13:27,133 {\an1}-The paying passengers on board the Hindenburg 275 00:13:27,166 --> 00:13:29,166 {\an1}trusted German ingenuity. 276 00:13:29,200 --> 00:13:31,800 {\an1}They trusted that this airship would get them 277 00:13:31,833 --> 00:13:33,966 from A to B safely. 278 00:13:36,333 --> 00:13:37,633 -Against the odds, 279 00:13:37,666 --> 00:13:40,033 the Hindenburg's first transatlantic flights 280 00:13:40,066 --> 00:13:43,300 were all successful. 281 00:13:43,333 --> 00:13:47,333 But a year later, on its 37th Atlantic crossing, 282 00:13:47,366 --> 00:13:50,033 {\an1}the airship's problematic size and inadequate 283 00:13:50,066 --> 00:13:52,366 {\an1}testing became apparent. 284 00:13:52,400 --> 00:13:53,666 {\an1}-There was a design flaw... 285 00:13:53,700 --> 00:13:55,566 Critical and fatal design flaw... 286 00:13:55,600 --> 00:13:56,566 On the Hindenburg. 287 00:13:56,600 --> 00:14:03,366 {\an8}♪♪♪ 288 00:14:03,400 --> 00:14:05,333 {\an8}-As the Hindenburg was coming into land 289 00:14:05,366 --> 00:14:08,266 {\an7}at Lakehurst Naval Air Station in New Jersey, 290 00:14:08,300 --> 00:14:11,900 {\an1}it was consumed by flames. 291 00:14:11,933 --> 00:14:15,833 {\an1}The 7 million cubic feet of hydrogen inside the airship 292 00:14:15,866 --> 00:14:19,133 {\an1}exploded almost instantaneously. 293 00:14:22,166 --> 00:14:23,600 {\an1}In less than a minute, 294 00:14:23,633 --> 00:14:26,143 - the - Hindenburg and its 97 passengers 295 00:14:26,200 --> 00:14:31,333 {\an1}and crew were enveloped in a gigantic fireball. 296 00:14:31,366 --> 00:14:35,000 {\an1}-The technology that created the Hindenburg  couldn't save it. 297 00:14:35,033 --> 00:14:38,433 {\an8}In 32 seconds, it went up in flames. 298 00:14:41,200 --> 00:14:43,800 {\an1}-The risk of using highly explosive hydrogen 299 00:14:43,833 --> 00:14:47,333 as a means to lift the ship was well known. 300 00:14:47,366 --> 00:14:49,366 -Not all of the ships got off the ground... 301 00:14:49,400 --> 00:14:51,400 {\an1}the V6 exploded in its hanger. 302 00:14:51,433 --> 00:14:54,500 {\an1}The hydrogen had been ignited by a stray spark. 303 00:14:54,533 --> 00:14:58,600 {\an1}-But nearly a decade earlier, the company's headstrong boss 304 00:14:58,633 --> 00:15:02,000 ignored the concerns of key administrators, 305 00:15:02,033 --> 00:15:07,033 and it was a decision that would prove fatal. 306 00:15:07,066 --> 00:15:08,466 {\an1}-The risks are very high. 307 00:15:08,500 --> 00:15:10,700 {\an1}And the fact that there were alternatives available, 308 00:15:10,733 --> 00:15:12,633 even if they had their shortcomings, 309 00:15:12,666 --> 00:15:16,100 {\an1}does suggest that the use of hydrogen in the Hindenburg 310 00:15:16,133 --> 00:15:18,833 did make this airship a ticking time bomb. 311 00:15:18,866 --> 00:15:26,866 {\an8}♪♪♪ 312 00:15:28,266 --> 00:15:30,900 {\an1}-In the early days of designing the Hindenburg, 313 00:15:30,933 --> 00:15:36,266 {\an1}company leader Hugo Eckener had a key decision to make... 314 00:15:36,300 --> 00:15:39,566 {\an1}Would his ambitious airship rely on hydrogen gas 315 00:15:39,600 --> 00:15:41,800 to provide its lift? 316 00:15:41,833 --> 00:15:45,466 {\an1}Or should he switch to a newer, and safer, alternative: 317 00:15:45,500 --> 00:15:47,000 helium? 318 00:15:47,033 --> 00:15:49,033 {\an1}-You want to fill your airship with a gas 319 00:15:49,066 --> 00:15:52,366 that is less dense than the air around it. 320 00:15:52,400 --> 00:15:57,366 {\an7}This produces a buoyancy force which pushes the airship up. 321 00:15:57,400 --> 00:16:01,100 {\an1}Hydrogen is the lightest chemical element. 322 00:16:01,133 --> 00:16:02,933 {\an1}It's the smallest atom, 323 00:16:02,966 --> 00:16:05,866 it occurs naturally on Earth as a gas, 324 00:16:05,900 --> 00:16:09,566 {\an1}and it's much less dense than air. 325 00:16:09,600 --> 00:16:12,833 Helium is the second lightest gas. 326 00:16:12,866 --> 00:16:15,100 The key advantage of choosing helium 327 00:16:15,133 --> 00:16:16,466 {\an1}over hydrogen in an airship 328 00:16:16,500 --> 00:16:18,500 is the fact that it is an inert gas 329 00:16:18,533 --> 00:16:21,533 {\an1}and so it doesn't represent an explosive risk. 330 00:16:21,566 --> 00:16:22,733 {\an7}-Hydrogen was cheaper. 331 00:16:22,766 --> 00:16:24,366 {\an7}It was more readily available. 332 00:16:24,400 --> 00:16:27,200 {\an1}It was capable of achieving a much greater lift 333 00:16:27,233 --> 00:16:28,509 so it could carry more passengers, 334 00:16:28,533 --> 00:16:30,133 {\an1}more weight in the gondola, 335 00:16:30,166 --> 00:16:33,100 {\an1}But the risk of it was it was flammable, highly flammable. 336 00:16:36,033 --> 00:16:37,900 {\an1}-Helium was likely a much safer, 337 00:16:37,933 --> 00:16:41,500 and more stable, option than explosive hydrogen. 338 00:16:41,533 --> 00:16:43,833 {\an1}But helium had problems too. 339 00:16:43,866 --> 00:16:46,066 {\an1}While also lighter than air, 340 00:16:46,100 --> 00:16:48,300 it was still heavier than hydrogen, 341 00:16:48,333 --> 00:16:52,300 {\an1}reducing its lift power and the number of passengers. 342 00:16:52,333 --> 00:16:54,633 And it was difficult to get ahold of. 343 00:16:54,666 --> 00:16:56,166 In the 1930s, 344 00:16:56,200 --> 00:16:59,966 {\an1}most of the world's helium was produced in the United States. 345 00:17:00,000 --> 00:17:03,366 -The U.S. had a monopoly on helium supply. 346 00:17:03,400 --> 00:17:06,666 {\an1}This presented a big problem to the engineers in Europe, 347 00:17:06,700 --> 00:17:09,233 {\an1}and they really didn't like the idea of relying 348 00:17:09,266 --> 00:17:12,033 {\an1}on U.S. imports of helium. 349 00:17:12,066 --> 00:17:13,666 -So a German company like Zeppelin 350 00:17:13,700 --> 00:17:16,000 {\an1}couldn't realistically build helium airships 351 00:17:16,033 --> 00:17:17,700 {\an1}without a huge amount of cost 352 00:17:17,733 --> 00:17:20,100 {\an1}and a huge amount of potential paperwork and diplomacy 353 00:17:20,133 --> 00:17:24,366 {\an1}trying to secure that gas from the United States. 354 00:17:24,400 --> 00:17:28,800 {\an1}-Hugo Eckener chose cost and availability over safety, 355 00:17:28,833 --> 00:17:34,500 {\an7}forging ahead with the use of hydrogen for his new airship. 356 00:17:34,533 --> 00:17:36,833 {\an7}But then, in October 1930, 357 00:17:36,866 --> 00:17:39,766 {\an8}seven years before the Hindenburg  disaster, 358 00:17:39,800 --> 00:17:43,833 {\an7}a tragic accident forced him to question his original decision. 359 00:17:43,866 --> 00:17:46,000 -Most of these men have a date with death... 360 00:17:46,033 --> 00:17:47,666 {\an1}but in the elevator up the mooring mast 361 00:17:47,700 --> 00:17:51,033 there's no hint of the holocaust to come. 362 00:17:51,066 --> 00:17:53,733 {\an1}-A British airship filled with hydrogen, 363 00:17:53,766 --> 00:17:57,043 {\an1}the 364 00:17:53,766 --> 00:18:00,366 exploded, killing 48 of its 56 passengers. 365 00:17:57,067 --> 00:18:02,700 R101, 366 00:18:02,700 --> 00:18:06,533 {\an1}-And this was all that remained of Britain's empress of the sky. 367 00:18:09,466 --> 00:18:13,100 {\an1}-After the R101  flaming disaster, 368 00:18:13,133 --> 00:18:17,566 {\an7}Hugo Eckener thought maybe we do need to use helium. 369 00:18:17,600 --> 00:18:21,866 -You give us helium for our merchant ships 370 00:18:21,900 --> 00:18:25,600 {\an1}and we will give you our large operating experiences 371 00:18:25,633 --> 00:18:27,500 in exchange. 372 00:18:27,533 --> 00:18:30,500 {\an1}And this way I believe the further development 373 00:18:30,533 --> 00:18:32,766 of the airship and airship traffic 374 00:18:32,800 --> 00:18:36,700 will be assured for the benefit of mankind. 375 00:18:36,733 --> 00:18:41,600 {\an1}-But, ultimately, Eckener continued to rely on hydrogen. 376 00:18:41,633 --> 00:18:44,233 {\an1}Zeppelin had an unblemished record of using it 377 00:18:44,266 --> 00:18:47,366 in all their previous airships. 378 00:18:47,400 --> 00:18:50,900 {\an1}Overconfident, Eckener ignored the warnings 379 00:18:50,933 --> 00:18:55,966 {\an1}and made the fatal decision to stick with the explosive gas. 380 00:18:56,000 --> 00:18:59,866 {\an1}-The historical record shows that no one told Hugo Eckener 381 00:18:59,900 --> 00:19:01,000 what to do. 382 00:19:01,033 --> 00:19:02,733 {\an1}He was absolutely bull-headed 383 00:19:02,766 --> 00:19:08,900 {\an1}in his determination to stay with hydrogen at all costs. 384 00:19:08,933 --> 00:19:13,133 -Hugo Eckener boasted about Zeppelin's safety record. 385 00:19:13,166 --> 00:19:18,200 {\an1}He boasted that German ingenuity could master the hydrogen 386 00:19:18,233 --> 00:19:21,600 {\an1}and that they could produce the best airships in the world. 387 00:19:21,633 --> 00:19:24,866 {\an1}It was this kind of arrogance, unfortunately, 388 00:19:24,900 --> 00:19:27,833 {\an1}that led to the disaster. 389 00:19:27,866 --> 00:19:30,033 -The decision to stay with hydrogen 390 00:19:30,066 --> 00:19:33,800 {\an1}meant that the Hindenburg was certain to blow up 391 00:19:33,833 --> 00:19:36,966 {\an1}fatally at some point. 392 00:19:37,000 --> 00:19:40,466 {\an1}-Had Eckener heeded the warnings about using hydrogen, 393 00:19:40,500 --> 00:19:42,460 the 394 00:19:42,484 --> 00:19:44,466 Hindenburg would never have exploded. 395 00:19:44,500 --> 00:19:46,700 {\an1}But his choice wasn't the only mistake 396 00:19:46,733 --> 00:19:49,333 that set the airship on the path to disaster. 397 00:19:49,366 --> 00:19:56,233 {\an8}♪♪♪ 398 00:19:56,266 --> 00:19:58,633 For the Hindenburg's maiden crossing, 399 00:19:58,666 --> 00:20:01,366 the passenger list was made up of celebrities, 400 00:20:01,400 --> 00:20:05,833 the wealthy elite, and journalists. 401 00:20:05,866 --> 00:20:09,266 {\an1}But now, new evidence reveals that even as these people 402 00:20:09,300 --> 00:20:11,866 were boarding, a critical design flaw 403 00:20:11,900 --> 00:20:17,300 {\an1}meant the Hindenburg's  time was already running out. 404 00:20:17,333 --> 00:20:18,477 -The 405 00:20:17,333 --> 00:20:19,666 had a dangerous rattle... 406 00:20:18,501 --> 00:20:19,700 Hindenburg 407 00:20:19,700 --> 00:20:22,233 {\an1}and this is a problem, and they know it. 408 00:20:22,266 --> 00:20:29,366 {\an8}♪♪♪ 409 00:20:29,400 --> 00:20:31,700 {\an8}-December 1935... 410 00:20:31,733 --> 00:20:35,600 {\an8}almost 18 months before the disaster. 411 00:20:35,633 --> 00:20:37,733 Zeppelin technicians were about to undertake 412 00:20:37,766 --> 00:20:39,500 {\an1}one of the most difficult steps 413 00:20:39,533 --> 00:20:41,833 {\an1}in of the Hindenburg's construction: 414 00:20:41,866 --> 00:20:46,166 Covering its vast aluminum frame with fabric. 415 00:20:46,200 --> 00:20:48,866 -The outer cover of the Hindenburg 416 00:20:48,900 --> 00:20:52,966 is one of the most extraordinary uses of fabric, 417 00:20:53,000 --> 00:20:54,666 probably of all time. 418 00:20:54,700 --> 00:20:59,233 We're talking about some seven acres of cloth. 419 00:20:59,266 --> 00:21:03,333 {\an1}-It was stretched across this skeleton of metal, 420 00:21:03,366 --> 00:21:05,033 {\an1}and this was really important 421 00:21:05,066 --> 00:21:08,266 {\an1}that the that the textile was fitted really snugly 422 00:21:08,300 --> 00:21:10,566 because if there's any sort of movement in that, 423 00:21:10,600 --> 00:21:14,266 {\an1}then the ship won't be able to fly efficiently. 424 00:21:14,300 --> 00:21:17,533 {\an1}-This highly skilled process was unique to Zeppelin, 425 00:21:17,566 --> 00:21:21,000 {\an1}and it had been perfected by the company's textiles expert, 426 00:21:21,033 --> 00:21:23,166 Karl Hurttle. 427 00:21:23,200 --> 00:21:25,833 {\an1}Hurttle spent two decades overseeing the covering 428 00:21:25,866 --> 00:21:29,533 of more than 50 of Zeppelin's airships. 429 00:21:29,566 --> 00:21:31,966 {\an1}-Karl Hurttle was sort of a secret weapon 430 00:21:32,000 --> 00:21:33,866 {\an1}of the Zeppelin Company. 431 00:21:33,900 --> 00:21:37,500 {\an1}He's really the world's expert on this. 432 00:21:37,533 --> 00:21:39,666 {\an1}-He had developed his own system 433 00:21:39,700 --> 00:21:42,566 {\an1}for creating a taut layer of waterproof fabric 434 00:21:42,600 --> 00:21:45,900 for the airship's vast skeleton. 435 00:21:45,933 --> 00:21:48,900 {\an1}-This is an incredibly involved process. 436 00:21:48,933 --> 00:21:52,100 {\an1}But in the end, what they end up with is something that is 437 00:21:52,133 --> 00:21:58,100 {\an1}very strong, very sturdy, and doesn't vibrate in the wind. 438 00:21:58,133 --> 00:22:01,166 {\an1}-But when the Hindenburg was ready to be covered... 439 00:22:01,200 --> 00:22:04,433 {\an1}Karl Hurttle wasn't there. 440 00:22:04,466 --> 00:22:09,066 He was now working in the United States. 441 00:22:09,100 --> 00:22:10,710 {\an1}With financial pressure to get the 442 00:22:09,100 --> 00:22:12,366 airborne, 443 00:22:10,734 --> 00:22:12,400 Hindenburg 444 00:22:12,400 --> 00:22:14,966 Zeppelin was forced to cover the airship 445 00:22:15,000 --> 00:22:19,733 without its most experienced fabric expert. 446 00:22:19,766 --> 00:22:23,333 {\an1}-This type of construction had never been attempted before. 447 00:22:23,366 --> 00:22:25,233 {\an1}This was the biggest airship ever made. 448 00:22:25,266 --> 00:22:29,133 {\an1}And so the fact that their chief textile engineer was away 449 00:22:29,166 --> 00:22:33,566 {\an1}overseas on a different project was really, really not ideal. 450 00:22:36,433 --> 00:22:38,900 {\an1}-And the colossal size of the Hindenburg 451 00:22:38,933 --> 00:22:42,266 {\an1}wasn't the only challenge for the technicians. 452 00:22:42,300 --> 00:22:45,033 {\an1}-The conditions were bitterly cold and wet. 453 00:22:45,066 --> 00:22:48,966 {\an1}This meant that the textile became waterlogged and icy, 454 00:22:49,000 --> 00:22:51,900 {\an1}and this caused the textile to become very stiff 455 00:22:51,933 --> 00:22:54,933 {\an1}and not very flexible. 456 00:22:54,966 --> 00:22:56,766 -It's like trying to put a dress on 457 00:22:56,800 --> 00:22:59,233 or a pair of jeans that are frozen. 458 00:22:59,266 --> 00:23:01,566 {\an1}They're just not going to quite fit on there. 459 00:23:01,600 --> 00:23:04,666 {\an1}And in fact, there was a Goodyear technician on hand 460 00:23:04,700 --> 00:23:08,066 {\an1}who observed the outer cover being put on the Hindenburg... 461 00:23:08,100 --> 00:23:09,633 {\an1}first time it was ever done... 462 00:23:09,666 --> 00:23:13,933 {\an1}who noted that, probably, given those conditions... 463 00:23:13,966 --> 00:23:16,733 The freezing weather and the dampness... 464 00:23:16,766 --> 00:23:19,433 That the outer cover was not going to be properly 465 00:23:19,466 --> 00:23:23,200 put on as firmly and tautly as it should be. 466 00:23:25,566 --> 00:23:27,600 {\an8}-When the Hindenburg was finished, 467 00:23:27,633 --> 00:23:33,033 {\an7}it took its first test flight on March 4, 1936, 468 00:23:33,066 --> 00:23:36,266 with just a handful of crewmembers aboard. 469 00:23:36,300 --> 00:23:39,933 And within minutes, they detected a problem. 470 00:23:39,966 --> 00:23:41,466 {\an1}-Once it was up in the skies, 471 00:23:41,500 --> 00:23:45,133 {\an1}they noticed a sort of fluttering of this textile 472 00:23:45,166 --> 00:23:47,833 {\an1}that was coating the Hindenburg. 473 00:23:47,866 --> 00:23:50,266 {\an1}What they didn't realize was that this fluttering 474 00:23:50,300 --> 00:23:51,800 was being transferred 475 00:23:51,833 --> 00:23:56,666 to the metal skeleton of the Hindenburg. 476 00:23:56,700 --> 00:23:57,933 -Back in the hangar, 477 00:23:57,966 --> 00:24:02,400 {\an1}the technicians desperately searched for a solution. 478 00:24:02,433 --> 00:24:05,466 {\an1}They attempted to make the outer cover fit more tightly 479 00:24:05,500 --> 00:24:09,200 {\an1}by applying a highly flammable fabric lacquer known as 480 00:24:09,233 --> 00:24:11,233 "aircraft dope." 481 00:24:11,266 --> 00:24:13,966 {\an1}-One of the things that the Zeppelin Company did 482 00:24:14,000 --> 00:24:18,233 {\an1}was to paint two extra coats of dope across the entire top. 483 00:24:18,266 --> 00:24:19,966 {\an1}Now, this is a significant amount of weight 484 00:24:20,000 --> 00:24:21,100 and a lot of expense, 485 00:24:21,133 --> 00:24:23,500 but the hope was that this would remove 486 00:24:23,533 --> 00:24:27,333 {\an1}the potentially destructive flutter. 487 00:24:27,366 --> 00:24:29,900 {\an1}-Despite these attempts to fix the problem, 488 00:24:29,933 --> 00:24:32,233 the fabric continued to flutter. 489 00:24:34,866 --> 00:24:38,400 {\an1}But the added drag and constant vibrations didn't seem 490 00:24:38,433 --> 00:24:41,433 {\an1}to affect the airship's overall flight performance, 491 00:24:41,466 --> 00:24:45,400 {\an1}so the problem went unsolved. 492 00:24:45,433 --> 00:24:48,533 {\an1}The fluttering fabric would play a more significant role 493 00:24:48,566 --> 00:24:50,593 {\an1}in the 494 00:24:48,566 --> 00:24:52,666 destruction than previously understood. 495 00:24:50,617 --> 00:24:52,700 Hindenburg's 496 00:24:52,700 --> 00:24:54,900 {\an1}-This issue of fluttering in an airship 497 00:24:54,933 --> 00:24:58,633 {\an1}was well known on the smaller ones that had come before. 498 00:24:58,666 --> 00:24:59,966 The difference with the Hindenburg 499 00:25:00,000 --> 00:25:03,166 {\an8}was that it was on a vastly larger scale, 500 00:25:03,200 --> 00:25:05,733 {\an7}so the problem became amplified in the same way 501 00:25:05,766 --> 00:25:07,900 {\an1}that the volume of the ship was amplified as well. 502 00:25:07,933 --> 00:25:10,500 {\an1}And so it wasn't known how much of a problem 503 00:25:10,533 --> 00:25:13,600 a large flutter would be with the Hindenburg. 504 00:25:13,633 --> 00:25:15,600 {\an1}Without that fluttering, it's possible that 505 00:25:15,633 --> 00:25:17,194 {\an1}the 506 00:25:15,633 --> 00:25:18,800 disaster could have been entirely avoided. 507 00:25:17,218 --> 00:25:18,833 {\an1}Hindenburg 508 00:25:18,833 --> 00:25:21,233 [ Explosion ] 509 00:25:23,500 --> 00:25:26,577 - {\an1}-Just moments into the  Hindenburg's  - maiden flight, 510 00:25:26,633 --> 00:25:30,800 {\an1}concerns about its sloppy construction were raised. 511 00:25:30,833 --> 00:25:33,400 {\an1}But the reason for its rushed construction happened 512 00:25:33,433 --> 00:25:38,200 five years earlier and affected millions of people. 513 00:25:38,233 --> 00:25:40,100 {\an1}-In 1929, the Wall Street crash 514 00:25:40,133 --> 00:25:41,900 had taken place in the United States, 515 00:25:41,933 --> 00:25:45,000 {\an1}and that unleashed the worldwide Great Depression. 516 00:25:45,033 --> 00:25:47,800 {\an1}So funding for large-scale industrial and technological 517 00:25:47,833 --> 00:25:51,166 enterprises began to wither away. 518 00:25:51,200 --> 00:25:54,666 -Germany's economy was on its knees... 519 00:25:54,700 --> 00:25:59,333 {\an1}and Hugo Eckener was worried about his budget. 520 00:25:59,366 --> 00:26:02,700 {\an1}Determined to keep his ambitious airship on track, 521 00:26:02,733 --> 00:26:07,633 {\an1}he brought in financial investors who sealed its fate. 522 00:26:07,666 --> 00:26:10,066 {\an1}-Trying to build the largest aircraft the world 523 00:26:10,100 --> 00:26:13,433 {\an1}has ever seen in the middle of the Great Depression 524 00:26:13,466 --> 00:26:15,533 was not good timing. 525 00:26:15,566 --> 00:26:19,733 {\an1}That meant that in order to salvage the project, 526 00:26:19,766 --> 00:26:22,600 {\an1}he had to cut some deals with the devil. 527 00:26:22,633 --> 00:26:30,633 {\an8}♪♪♪ 528 00:26:32,300 --> 00:26:34,500 {\an7}-In the summer of 1933... 529 00:26:34,533 --> 00:26:37,400 {\an8}four years before the Hindenburg  exploded... 530 00:26:37,433 --> 00:26:39,900 {\an7}Eckener appealed to Hitler's propaganda minister, 531 00:26:39,933 --> 00:26:41,166 {\an8}Joseph Goebbels, 532 00:26:41,200 --> 00:26:45,866 {\an7}for financial help to finish the giant airship. 533 00:26:45,900 --> 00:26:49,666 {\an8}Goebbels jumped at the opportunity. 534 00:26:49,700 --> 00:26:52,500 {\an7}-So the Hindenburg  was seen by Nazi party leadership, 535 00:26:52,533 --> 00:26:55,766 {\an7}particularly Joseph Goebbels, as a massive propaganda coup. 536 00:26:55,800 --> 00:26:58,166 {\an8}Airships were this symbol of greatness, 537 00:26:58,200 --> 00:27:01,733 {\an7}of technological progress, of luxury. 538 00:27:01,766 --> 00:27:03,933 {\an7}-To finish the pioneering airship, 539 00:27:03,966 --> 00:27:05,866 {\an7}the Nazi regime invested funds 540 00:27:05,900 --> 00:27:10,533 {\an7}totaling the equivalent of more than $10 million today. 541 00:27:10,566 --> 00:27:12,700 {\an7}-There's no such thing as a free lunch, 542 00:27:12,733 --> 00:27:17,633 {\an7}and the money that the Nazis gave had strings attached. 543 00:27:17,666 --> 00:27:20,000 -After five years of construction, 544 00:27:20,033 --> 00:27:22,660 {\an1}the 545 00:27:20,033 --> 00:27:25,333 was finally finished in March 1936. 546 00:27:22,684 --> 00:27:25,366 Hindenburg 547 00:27:25,366 --> 00:27:29,333 {\an1}Goebbels almost immediately put his propaganda machine to work, 548 00:27:29,366 --> 00:27:33,500 emblazoning the ship with Nazi swastikas. 549 00:27:33,533 --> 00:27:36,433 {\an1}Instead of test flights over the open ocean, 550 00:27:36,466 --> 00:27:39,733 {\an1}he commandeered the airship for short publicity flights 551 00:27:39,766 --> 00:27:43,466 over Germany to increase Nazi popularity. 552 00:27:43,500 --> 00:27:44,909 {\an1}-The Hindenburg  became the means 553 00:27:44,933 --> 00:27:49,900 {\an1}by which the Nazis promoted their philosophy to the skies. 554 00:27:49,933 --> 00:27:51,527 {\an1}-The 555 00:27:49,933 --> 00:27:53,166 became this symbol of Nazi Germany 556 00:27:51,551 --> 00:27:53,200 Hindenburg 557 00:27:53,200 --> 00:27:54,566 in many respects, 558 00:27:54,600 --> 00:27:56,976 {\an1}and that would have put enormous pressure on the Zeppelin Company 559 00:27:57,000 --> 00:27:59,966 {\an1}and on the crew of the airship to perform perfectly. 560 00:28:00,000 --> 00:28:02,400 {\an1}[ Cheers and applause ] 561 00:28:02,433 --> 00:28:03,660 {\an1}-The 562 00:28:02,433 --> 00:28:04,933 became a stand-in for Nazi 563 00:28:03,684 --> 00:28:04,966 Hindenburg 564 00:28:04,966 --> 00:28:09,033 {\an1}Germany's technical prowess and mechanical expertise... 565 00:28:09,066 --> 00:28:14,400 {\an1}without ever being properly tested for long-range flight. 566 00:28:14,433 --> 00:28:16,566 {\an1}-We can see here the ways in which this new technology 567 00:28:16,600 --> 00:28:18,766 has been appropriated by the Nazi party 568 00:28:18,800 --> 00:28:20,266 {\an1}who helped to fund it. 569 00:28:20,300 --> 00:28:22,800 {\an1}Before it's even had a chance to serve its commercial purposes, 570 00:28:22,833 --> 00:28:25,033 {\an1}it's already being deployed as a propaganda tool 571 00:28:25,066 --> 00:28:27,633 for the Nazi regime. 572 00:28:27,666 --> 00:28:30,333 -The Zeppelin Company took shortcuts. 573 00:28:30,366 --> 00:28:33,366 {\an1}They took shortcuts because of the pressure they were under. 574 00:28:33,400 --> 00:28:37,433 {\an1}There was too much support behind it for it to fail. 575 00:28:41,333 --> 00:28:44,333 {\an1}-Keen to start making money on their investment, 576 00:28:44,366 --> 00:28:45,543 Zeppelin scheduled the 577 00:28:44,366 --> 00:28:46,766 first 578 00:28:45,567 --> 00:28:46,800 Hindenburg's 579 00:28:46,800 --> 00:28:49,066 commercial flight. 580 00:28:49,100 --> 00:28:51,900 But the limited safety testing... 581 00:28:51,933 --> 00:28:54,700 {\an1}ill-fitting outer covering... 582 00:28:54,733 --> 00:28:58,400 {\an1}and pressure from the Nazis to showcase perfection... 583 00:28:58,433 --> 00:29:01,633 left the Hindenburg compromised. 584 00:29:01,666 --> 00:29:04,533 {\an1}It was only a matter of time before the shortcuts 585 00:29:04,566 --> 00:29:06,200 were revealed. 586 00:29:09,833 --> 00:29:11,233 To this day, 587 00:29:11,266 --> 00:29:13,560 {\an1}the 588 00:29:11,266 --> 00:29:15,900 remains the largest aircraft ever flown. 589 00:29:13,584 --> 00:29:15,933 Hindenburg 590 00:29:15,933 --> 00:29:18,466 {\an1}The airship was the culmination of a movement 591 00:29:18,500 --> 00:29:21,033 toward lighter-than-air transportation 592 00:29:21,066 --> 00:29:25,900 that began eight decades earlier. 593 00:29:25,933 --> 00:29:29,700 In 1852, the world's first airship, 594 00:29:29,733 --> 00:29:32,333 {\an1}built by French inventor Henri Giffard, 595 00:29:32,366 --> 00:29:35,533 flew a distance of more than 20 miles. 596 00:29:35,566 --> 00:29:40,033 {\an1}But it was German inventor Graf Von Zeppelin who, in 1900, 597 00:29:40,066 --> 00:29:43,266 {\an1}successfully demonstrated the real potential 598 00:29:43,300 --> 00:29:45,766 {\an1}of the motorized airship. 599 00:29:45,800 --> 00:29:49,700 {\an1}-It was a transition from simply getting up into the air 600 00:29:49,733 --> 00:29:53,166 {\an7}and being able to move where the wind took you, 601 00:29:53,200 --> 00:29:56,900 {\an7}to getting up into the air and steering against the wind, 602 00:29:56,933 --> 00:30:00,600 {\an8}which is a big, big step in aviation. 603 00:30:00,633 --> 00:30:02,500 {\an7}-The secret to Zeppelin's concept 604 00:30:02,533 --> 00:30:06,700 {\an8}lay inside the ship's protective fabric covering: 605 00:30:06,733 --> 00:30:09,766 {\an8}A series of gasbags provided the airship 606 00:30:09,800 --> 00:30:12,966 {\an8}with enough buoyancy to carry an engine... 607 00:30:13,000 --> 00:30:15,133 {\an8}and a payload. 608 00:30:15,166 --> 00:30:16,976 {\an7}-Of course if you've got a lot of gas balloons, 609 00:30:17,000 --> 00:30:18,133 {\an7}you've got a lot of payload, 610 00:30:18,166 --> 00:30:20,000 {\an8}so you can carry a really big engine. 611 00:30:20,033 --> 00:30:22,033 {\an8}You can have multiple propellers, 612 00:30:22,066 --> 00:30:25,933 {\an8}and that that was his breakthrough. 613 00:30:25,966 --> 00:30:28,166 -Zeppelin demonstrated that air travel 614 00:30:28,200 --> 00:30:30,333 could be more than a recreational activity 615 00:30:30,366 --> 00:30:33,733 for adventurers and thrill seekers. 616 00:30:33,766 --> 00:30:39,766 {\an1}The airship had the potential to be used for a great deal more. 617 00:30:39,800 --> 00:30:43,000 {\an1}-And this is really where the Zeppelin makes its mark, 618 00:30:43,033 --> 00:30:46,466 {\an1}because it's really the first craft that can reasonably 619 00:30:46,500 --> 00:30:49,433 and predictably steer where it wants to go, 620 00:30:49,466 --> 00:30:52,000 {\an1}take off where it wants to go, and land where it wants to go. 621 00:30:52,033 --> 00:30:53,342 {\an1}Remember, this is a time when no one 622 00:30:53,366 --> 00:30:55,366 had ever been sort of air lifted up 623 00:30:55,400 --> 00:30:57,433 {\an1}and suddenly looking down on the world. 624 00:30:57,466 --> 00:31:00,866 {\an1}So this was quite a novelty at the time - 625 00:31:00,900 --> 00:31:03,000 and that was the plan after the war, 626 00:31:03,033 --> 00:31:08,600 {\an1}was to create a passenger service for an airline. 627 00:31:08,633 --> 00:31:12,100 -By the time disaster struck in 1937, 628 00:31:12,133 --> 00:31:13,844 {\an1}the 629 00:31:12,133 --> 00:31:15,600 had already delivered on its promise 630 00:31:13,868 --> 00:31:15,633 Hindenburg 631 00:31:15,633 --> 00:31:19,866 {\an1}to be the world leader in international aviation. 632 00:31:19,900 --> 00:31:21,733 {\an1}In its first nine months, 633 00:31:21,766 --> 00:31:25,633 it made 34 successful Atlantic crossings... 634 00:31:25,666 --> 00:31:28,766 {\an1}and flew almost 3,000 passengers 635 00:31:28,800 --> 00:31:33,066 {\an1}between Europe and North and South America in record time. 636 00:31:33,100 --> 00:31:34,276 {\an1}-It's been an incredible season. 637 00:31:34,300 --> 00:31:38,633 200,000 miles, not a single problem. 638 00:31:38,666 --> 00:31:41,133 -But the Hindenburg's shimmering canvas 639 00:31:41,166 --> 00:31:44,666 {\an1}was hiding a deadly problem. 640 00:31:44,700 --> 00:31:46,500 {\an1}One of the giant gasbags, 641 00:31:46,533 --> 00:31:49,333 containing the highly explosive hydrogen, 642 00:31:49,366 --> 00:31:51,933 {\an1}was on the brink of rupturing... 643 00:31:51,966 --> 00:31:54,933 {\an1}and no one had noticed. 644 00:31:54,966 --> 00:32:01,566 {\an1}-Any leak of hydrogen on an airship is potentially fatal. 645 00:32:01,600 --> 00:32:05,866 If you have gasbags that are damaged, 646 00:32:05,900 --> 00:32:08,933 there's no telling how much hydrogen can escape. 647 00:32:08,966 --> 00:32:12,133 {\an1}It's clearly a catastrophic problem. 648 00:32:12,166 --> 00:32:20,166 {\an8}♪♪♪ 649 00:32:21,933 --> 00:32:23,966 {\an8}-In December 1936... 650 00:32:24,000 --> 00:32:27,566 {\an8}five months before the Hindenburg  exploded... 651 00:32:27,600 --> 00:32:28,733 The colossal airship 652 00:32:28,766 --> 00:32:33,033 {\an1}was undergoing its first major overhaul. 653 00:32:33,066 --> 00:32:37,833 {\an1}After a triumphant first year, 10 new cabins were installed 654 00:32:37,866 --> 00:32:40,266 to increase the airship's capacity 655 00:32:40,300 --> 00:32:44,100 {\an1}and help make the Hindenburg profitable for the first time. 656 00:32:44,133 --> 00:32:47,800 {\an1}-They proved the concept that luxury travel was possible, 657 00:32:47,833 --> 00:32:51,200 {\an1}they could do the distances, that people wanted to do it. 658 00:32:51,233 --> 00:32:54,600 {\an1}There was massive demand and they could do it in luxury, 659 00:32:54,633 --> 00:32:57,500 but they just couldn't make money. 660 00:32:57,533 --> 00:33:00,166 {\an1}-To create the additional cabin space, 661 00:33:00,200 --> 00:33:03,933 {\an1}the shape of one of the airship's 16 hydrogen gasbags 662 00:33:03,966 --> 00:33:06,266 had to be changed. 663 00:33:06,300 --> 00:33:08,433 {\an1}-It's like altering a dress or a jacket. 664 00:33:08,466 --> 00:33:13,833 {\an1}They needed to refit this gasbag for additional passenger cabins. 665 00:33:13,866 --> 00:33:15,200 {\an1}-A maintenance report... 666 00:33:15,233 --> 00:33:17,366 {\an1}only recently discovered in the archives 667 00:33:17,400 --> 00:33:20,000 {\an1}at the University of Texas at Dallas... 668 00:33:20,033 --> 00:33:23,233 Documents how, during the remodeling process, 669 00:33:23,266 --> 00:33:26,566 an alarming problem was discovered. 670 00:33:26,600 --> 00:33:28,666 -When the workmen pull the gasbag out, 671 00:33:28,700 --> 00:33:32,400 {\an1}they discover chafing abrasions at the top of it 672 00:33:32,433 --> 00:33:36,200 that made it vulnerable to a leak. 673 00:33:36,233 --> 00:33:39,733 {\an1}-Once again, the airship's ill-fitting outer skin 674 00:33:39,766 --> 00:33:42,066 {\an1}was the source of the trouble. 675 00:33:42,100 --> 00:33:45,066 {\an1}The vibrations caused by the fluttering fabric 676 00:33:45,100 --> 00:33:49,066 loosened the wires that kept the gasbag in place. 677 00:33:49,100 --> 00:33:53,233 {\an1}In turn, those wires then rubbed against the cotton fabric 678 00:33:53,266 --> 00:33:57,133 of the gasbag, wearing it dangerously thin. 679 00:33:57,166 --> 00:34:01,366 {\an1}-Some protective wiring that was supposed to increase 680 00:34:01,400 --> 00:34:03,166 {\an1}the safety of the gasbags 681 00:34:03,200 --> 00:34:06,666 actually was having the opposite effect. 682 00:34:06,700 --> 00:34:09,800 {\an1}-And so by compromising the structural integrity 683 00:34:09,833 --> 00:34:11,300 {\an8}of those gasbags, 684 00:34:11,333 --> 00:34:14,400 {\an7}that's representing a risk point of hydrogen 685 00:34:14,433 --> 00:34:16,600 {\an1}potentially leaking out. 686 00:34:18,633 --> 00:34:21,333 {\an1}-The same maintenance report goes on to reveal that, 687 00:34:21,366 --> 00:34:24,500 {\an1}although the damaged gasbag was fixed, 688 00:34:24,533 --> 00:34:28,433 {\an1}the wires meant to hold it in place were simply tied back 689 00:34:28,466 --> 00:34:32,433 {\an1}and not properly secured. 690 00:34:32,466 --> 00:34:35,666 {\an1}-It's incredible that the best solution that they could 691 00:34:35,700 --> 00:34:40,666 {\an1}come up with for a technological wonder was tape and twine. 692 00:34:40,700 --> 00:34:44,800 In the end, clearly, it didn't work. 693 00:34:44,833 --> 00:34:47,800 {\an1}-This, to me, seems like a little bit of a patch solution, 694 00:34:47,833 --> 00:34:51,433 {\an1}considering that the hydrogen gasbags are so important 695 00:34:51,466 --> 00:34:53,400 and their integrity 696 00:34:53,433 --> 00:34:57,266 is pretty crucial to the safety of the aircraft. 697 00:34:57,300 --> 00:35:00,033 {\an1}-The damage may have been patched up, 698 00:35:00,066 --> 00:35:02,433 but the Zeppelin team was still no closer 699 00:35:02,466 --> 00:35:07,300 {\an1}to resolving the issue with the airship's fluttering fabric. 700 00:35:07,333 --> 00:35:09,166 -They thought that they'd limited 701 00:35:09,200 --> 00:35:10,966 {\an1}the extent of the damage, 702 00:35:11,000 --> 00:35:13,300 {\an1}but why it was happening was still a puzzle 703 00:35:13,333 --> 00:35:16,333 {\an7}that they were intently working on. 704 00:35:16,366 --> 00:35:20,366 {\an7}-Just days after the potential hydrogen leak was fixed, 705 00:35:20,400 --> 00:35:24,800 {\an7}the Hindenburg  began the countdown to its second season. 706 00:35:24,833 --> 00:35:28,433 {\an1}The airship's design flaws and makeshift repairs 707 00:35:28,466 --> 00:35:31,700 had turned it into a ticking time bomb. 708 00:35:31,733 --> 00:35:35,533 {\an1}And one senior member of the Zeppelin team realized 709 00:35:35,566 --> 00:35:38,100 just how dangerous it had become. 710 00:35:38,133 --> 00:35:40,166 {\an1}But he chose to keep quiet. 711 00:35:40,200 --> 00:35:47,700 {\an8}♪♪♪ 712 00:35:47,733 --> 00:35:50,766 {\an1}For the fateful 1937 season, 713 00:35:50,800 --> 00:35:52,860 {\an1}the 714 00:35:50,800 --> 00:35:54,966 would be flown by several different captains. 715 00:35:52,884 --> 00:35:55,000 {\an1}Hindenburg 716 00:35:55,000 --> 00:35:59,433 {\an1}Each one had been personally trained by best in the business. 717 00:35:59,466 --> 00:36:02,266 -Ernst Lehmann was the most experienced 718 00:36:02,300 --> 00:36:03,733 {\an1}Zeppelin pilot in the world. 719 00:36:03,766 --> 00:36:05,266 {\an1}He flew through World War I. 720 00:36:05,300 --> 00:36:07,800 {\an1}He was trained by Hugo Eckener. 721 00:36:07,833 --> 00:36:12,100 {\an1}Lehmann is one of the chief pilots for the Hindenburg. 722 00:36:12,133 --> 00:36:17,133 {\an1}He knows it, every inch, bow to stern. 723 00:36:17,166 --> 00:36:19,700 -Now, a letter, recently discovered 724 00:36:19,733 --> 00:36:22,366 in the records of the Bureau of Air Commerce, 725 00:36:22,400 --> 00:36:26,433 {\an1}shows Lehmann knew about the damaged gasbag... 726 00:36:26,466 --> 00:36:29,600 {\an1}and the shoddy repairs. 727 00:36:29,633 --> 00:36:32,466 {\an1}-He told a good friend of his named Leonhard Adelt, 728 00:36:32,500 --> 00:36:33,900 who was a journalist, 729 00:36:33,933 --> 00:36:37,433 {\an1}that he had very deep worries about the Hindenburg 730 00:36:37,466 --> 00:36:39,666 {\an1}because of the gasbag damage. 731 00:36:39,700 --> 00:36:42,400 {\an1}This is very secretive information. 732 00:36:42,433 --> 00:36:46,200 {\an1}This is not well known outside the company 733 00:36:46,233 --> 00:36:49,700 and barely known inside the company. 734 00:36:49,733 --> 00:36:52,033 {\an1}So he's really confided something in someone 735 00:36:52,066 --> 00:36:55,166 {\an1}he really respects and trusts. 736 00:36:55,200 --> 00:36:57,100 {\an1}-Written by Leonhard Adelt, 737 00:36:57,133 --> 00:36:59,133 the letter reveals that Lehmann was prepared 738 00:36:59,166 --> 00:37:04,066 {\an1}to make a major personal sacrifice to prevent disaster. 739 00:37:04,100 --> 00:37:07,233 {\an1}-Lehmann tells Leonhard Adelt, "I'm so worried about this 740 00:37:07,266 --> 00:37:09,433 that I will fly on the Hindenburg 741 00:37:09,466 --> 00:37:14,166 {\an1}because there may be a problem and the experience of the staff 742 00:37:14,200 --> 00:37:16,866 {\an1}and the crew won't be enough to handle it. 743 00:37:16,900 --> 00:37:18,400 {\an1}I will be there to help." 744 00:37:18,433 --> 00:37:19,933 We never knew this. 745 00:37:19,966 --> 00:37:23,700 {\an1}This was an incredible admission by Captain Lehmann 746 00:37:23,733 --> 00:37:26,800 of a real problem on the Hindenburg. 747 00:37:26,833 --> 00:37:31,333 -On May 3, 1937, Lehmann boarded the Hindenburg 748 00:37:31,366 --> 00:37:34,800 for what would be its final flight. 749 00:37:34,833 --> 00:37:37,400 {\an1}-It's clear from the fact that Lehmann agreed to fly 750 00:37:37,433 --> 00:37:39,033 on the final flight 751 00:37:39,066 --> 00:37:43,233 that he expected some sort of problems, 752 00:37:43,266 --> 00:37:45,000 but ones that could be manageable. 753 00:37:45,033 --> 00:37:47,733 {\an1}I don't think he anticipated catastrophe. 754 00:37:47,766 --> 00:37:49,666 {\an1}I think he thought difficulty, 755 00:37:49,700 --> 00:37:52,100 grave difficulty, but not catastrophe. 756 00:37:54,466 --> 00:37:58,733 {\an1}-By noon on May 5th... The day before the crash... 757 00:37:58,766 --> 00:38:00,960 {\an1}the 758 00:37:58,766 --> 00:38:03,200 was 1,000 miles from its destination... 759 00:38:00,984 --> 00:38:03,233 {\an1}Hindenburg 760 00:38:03,233 --> 00:38:04,666 {\an1}which would play its own key 761 00:38:04,700 --> 00:38:08,966 part in the airship's destruction. 762 00:38:09,000 --> 00:38:12,166 {\an1}-The reason they chose Lakehurst was proximity to the cities, 763 00:38:12,200 --> 00:38:14,300 {\an1}but it's prone to sea fog 764 00:38:14,333 --> 00:38:17,366 {\an1}and it's prone to other bad weather phenomena. 765 00:38:17,400 --> 00:38:20,866 {\an1}So it's actually a rotten place to build an airship base. 766 00:38:20,900 --> 00:38:28,900 {\an8}♪♪♪ 767 00:38:29,833 --> 00:38:33,500 {\an7}-Nearly 20 years earlier, when many believed the airship 768 00:38:33,533 --> 00:38:36,133 was the future of international travel, 769 00:38:36,166 --> 00:38:38,900 {\an1}the U.S. Navy built a new facility 770 00:38:38,933 --> 00:38:40,600 {\an1}in Lakehurst, New Jersey. 771 00:38:42,700 --> 00:38:46,966 {\an1}They spent the equivalent of $140 million, 772 00:38:47,000 --> 00:38:51,500 {\an1}hoping to make a profit on this new form of transportation. 773 00:38:51,533 --> 00:38:55,433 {\an1}-The Lakehurst base was absolutely the pinnacle 774 00:38:55,466 --> 00:38:57,966 {\an7}of airship development in the United States. 775 00:38:58,000 --> 00:39:01,966 {\an8}It had the largest airship facility in the world. 776 00:39:02,000 --> 00:39:03,933 {\an8}It was, in fact, the largest room 777 00:39:03,966 --> 00:39:05,433 {\an7}ever constructed in the world 778 00:39:05,466 --> 00:39:08,100 {\an8}in order to house these enormous airships. 779 00:39:08,133 --> 00:39:09,909 {\an8}-In the same way that the Hindenburg  was a flagship 780 00:39:09,933 --> 00:39:11,900 {\an7}for German airship engineering, 781 00:39:11,933 --> 00:39:15,200 {\an8}so Lakehurst was a flagship site for the U.S. 782 00:39:15,233 --> 00:39:18,800 kind of investment in airships ships as well. 783 00:39:18,833 --> 00:39:21,266 -But despite its impressive infrastructure, 784 00:39:21,300 --> 00:39:24,600 {\an1}there was a major problem with the site. 785 00:39:24,633 --> 00:39:27,333 {\an1}Lakehurst was a terrible location, 786 00:39:27,366 --> 00:39:30,000 exposed and prone to bad weather 787 00:39:30,033 --> 00:39:32,833 coming straight off the North Atlantic. 788 00:39:32,866 --> 00:39:35,100 {\an1}-The optimal placement for safety 789 00:39:35,133 --> 00:39:38,133 {\an1}and function of any airship base 790 00:39:38,166 --> 00:39:41,033 {\an1}is a hundred miles inland. 791 00:39:41,066 --> 00:39:43,866 {\an1}Lakehurst was 14 miles inland. 792 00:39:43,900 --> 00:39:46,566 {\an1}-The Lakehurst airbase was renowned 793 00:39:46,600 --> 00:39:49,033 {\an1}for being troubled by storms... 794 00:39:49,066 --> 00:39:52,500 Not an ideal scenario if you trying to land an airship 795 00:39:52,533 --> 00:39:55,266 that is filled with hydrogen gas. 796 00:39:57,633 --> 00:40:02,833 {\an7}-In 1927, nearly 10 years before the Hindenburg  disaster, 797 00:40:02,866 --> 00:40:04,610 an American airship, the 798 00:40:04,634 --> 00:40:06,400 USS Los Angeles, 799 00:40:06,433 --> 00:40:09,733 {\an1}was caught by a gust of wind. 800 00:40:09,766 --> 00:40:14,100 {\an1}A photographer captured the incredible moment on film. 801 00:40:14,133 --> 00:40:17,666 {\an1}-At Lakehurst, the Los Angeles has its tail turned vertical 802 00:40:17,700 --> 00:40:19,933 {\an1}by the strength of the wind. 803 00:40:19,966 --> 00:40:26,400 {\an1}-It makes the airship stand fully up with people inside. 804 00:40:26,433 --> 00:40:29,566 {\an1}People are falling down, things are crashing down, 805 00:40:29,600 --> 00:40:33,933 {\an1}gasoline's flooding down. 806 00:40:33,966 --> 00:40:36,900 {\an1}And only after several minutes did the air breeze stop 807 00:40:36,933 --> 00:40:40,733 {\an1}and it dropped back down onto its side. 808 00:40:40,766 --> 00:40:42,833 {\an1}-I think it's fair to say that it was not the ideal 809 00:40:42,866 --> 00:40:44,466 {\an1}location for an airship base, 810 00:40:44,500 --> 00:40:47,133 in a place that was constantly buffeted by storms, 811 00:40:47,166 --> 00:40:49,933 {\an1}both in terms of strong winds and in terms of thunderstorms 812 00:40:49,966 --> 00:40:52,233 {\an1}with electrical charge. 813 00:40:52,266 --> 00:40:56,500 {\an1}-Despite concerns after the USS Los Angeles  incident, 814 00:40:56,533 --> 00:40:59,100 {\an1}the Navy's financial investment in Lakehurst 815 00:40:59,133 --> 00:41:01,500 {\an1}kept the facility open. 816 00:41:01,533 --> 00:41:04,366 {\an1}And the decision seemed like a smart one. 817 00:41:04,400 --> 00:41:08,633 For the next 10 years there were no major incidents. 818 00:41:11,300 --> 00:41:15,733 {\an8}Until May 6, 1937. 819 00:41:15,766 --> 00:41:17,893 {\an7}At 11:30 AM, on the day of the 820 00:41:15,766 --> 00:41:20,066 {\an8}disaster, 821 00:41:17,917 --> 00:41:20,100 {\an8}Hindenburg 822 00:41:20,100 --> 00:41:22,733 the commander of the U.S. Naval Air Station 823 00:41:22,766 --> 00:41:26,233 received a disturbing weather report. 824 00:41:26,266 --> 00:41:28,233 {\an1}Flying conditions in the area 825 00:41:28,266 --> 00:41:32,700 were described as "average to undesirable." 826 00:41:32,733 --> 00:41:33,977 {\an1}The 827 00:41:32,733 --> 00:41:35,266 was just six-and-a-half hours 828 00:41:34,001 --> 00:41:35,300 Hindenburg 829 00:41:35,300 --> 00:41:38,100 {\an1}away from its destination. 830 00:41:38,133 --> 00:41:41,166 {\an1}Approaching the east coast of the United States, 831 00:41:41,200 --> 00:41:42,677 {\an1}the 832 00:41:41,200 --> 00:41:44,200 was already behind schedule, 833 00:41:42,701 --> 00:41:44,233 Hindenburg 834 00:41:44,233 --> 00:41:47,033 {\an1}delayed by a strong headwind. 835 00:41:47,066 --> 00:41:50,633 {\an1}This delay to the Hindenburg's arrival in New Jersey 836 00:41:50,666 --> 00:41:53,666 {\an1}would prove to be deadly. 837 00:41:53,700 --> 00:41:56,433 -There was actually a one-hour window 838 00:41:56,466 --> 00:41:59,466 when the weather was completely clear over Lakehurst, 839 00:41:59,500 --> 00:42:00,900 {\an1}meaning that the Hindenburg 840 00:42:00,933 --> 00:42:03,033 could have landed in perfect safety 841 00:42:03,066 --> 00:42:05,100 {\an1}had it have been there at that time. 842 00:42:05,133 --> 00:42:11,600 {\an8}♪♪♪ 843 00:42:11,633 --> 00:42:13,633 {\an1}-The Hindenburg  had been scheduled to arrive 844 00:42:13,666 --> 00:42:17,733 {\an1}at Lakehurst airship base at 6:00 AM. 845 00:42:17,766 --> 00:42:22,433 {\an1}But the winds had cut the airship's speed almost in half. 846 00:42:22,466 --> 00:42:23,809 {\an1}-The Hindenburg  normally travels 847 00:42:23,833 --> 00:42:25,933 at 70 miles per hour at a cruising speed. 848 00:42:25,966 --> 00:42:27,500 It's down to 55. 849 00:42:27,533 --> 00:42:29,600 Within a day, it's down to 37. 850 00:42:29,633 --> 00:42:31,100 It's barely moving. 851 00:42:31,133 --> 00:42:33,666 {\an1}The outer cover is fluttering tremendously 852 00:42:33,700 --> 00:42:37,000 and taking the brunt of all these heavy headwinds. 853 00:42:37,033 --> 00:42:39,233 {\an1}-The Hindenburg  had been delayed on its journey, 854 00:42:39,266 --> 00:42:41,066 {\an1}so the captain had radioed ahead 855 00:42:41,100 --> 00:42:44,700 to the base to tell of this delay 856 00:42:44,733 --> 00:42:48,300 {\an1}-The landing was rescheduled for 6:00 PM 857 00:42:48,333 --> 00:42:52,733 {\an1}and the ground crew was ordered to stand down until then. 858 00:42:52,766 --> 00:42:55,733 {\an1}But, as the Hindenburg approached the U.S. coastline, 859 00:42:55,766 --> 00:42:58,100 the winds dropped and the airship 860 00:42:58,133 --> 00:43:01,633 {\an1}began to make up lost time. 861 00:43:01,666 --> 00:43:03,400 At around 4:00 PM, 862 00:43:03,433 --> 00:43:05,210 {\an1}the 863 00:43:03,433 --> 00:43:07,033 was finally approaching Lakehurst. 864 00:43:05,234 --> 00:43:07,066 Hindenburg 865 00:43:07,066 --> 00:43:10,300 {\an1}Conditions were unsettled, but a short break in the weather 866 00:43:10,333 --> 00:43:13,600 {\an1}provided an opportunity to land. 867 00:43:13,633 --> 00:43:16,333 But now there was another problem. 868 00:43:16,366 --> 00:43:19,200 {\an1}Because the Hindenburg's  speed had increased, 869 00:43:19,233 --> 00:43:23,633 {\an1}the ship was now two hours ahead of its revised time of arrival 870 00:43:23,666 --> 00:43:26,733 and the ground crew was nowhere to be found. 871 00:43:26,766 --> 00:43:28,400 -Generally, an airship would take 872 00:43:28,433 --> 00:43:31,666 {\an1}over 300 people to bring it in, 873 00:43:31,700 --> 00:43:34,100 {\an1}people who are literally pulling on ropes 874 00:43:34,133 --> 00:43:35,433 {\an1}that are going up to the ship 875 00:43:35,466 --> 00:43:38,400 {\an1}and helping bring it back to the ground. 876 00:43:38,433 --> 00:43:41,133 {\an1}-It becomes a huge operation, but also one that's only ever 877 00:43:41,166 --> 00:43:43,966 rolled out at a time when an airship is coming in. 878 00:43:46,433 --> 00:43:47,966 -With the ground crew not scheduled 879 00:43:48,000 --> 00:43:50,666 to return to the base for another two hours, 880 00:43:50,700 --> 00:43:52,394 the 881 00:43:52,418 --> 00:43:54,133 Hindenburg was forced to wait. 882 00:43:54,166 --> 00:43:55,300 {\an1}-The Hindenburg  ended up 883 00:43:55,333 --> 00:43:56,900 {\an1}circling around the base for a while, 884 00:43:56,933 --> 00:43:59,166 while the ground crew scrambled themselves together 885 00:43:59,200 --> 00:44:00,733 {\an1}and got ready for the landing. 886 00:44:00,766 --> 00:44:02,766 [ Thunder rumbles ] 887 00:44:02,800 --> 00:44:05,900 {\an1}-But as the Hindenburg  stayed in its holding pattern, 888 00:44:05,933 --> 00:44:08,833 {\an1}the weather grew much worse. 889 00:44:08,866 --> 00:44:12,833 {\an1}-Landing an airship is difficult in the best weather conditions, 890 00:44:12,866 --> 00:44:15,600 {\an1}but here we have churning skies, 891 00:44:15,633 --> 00:44:19,866 {\an1}there had been thunderstorms throughout the area all day. 892 00:44:19,900 --> 00:44:24,433 {\an1}-At 5:12 PM, Lakehurst base commander Charles Rosendahl 893 00:44:24,466 --> 00:44:28,100 {\an1}finally gave the Hindenburg clearance to land. 894 00:44:28,133 --> 00:44:32,333 {\an1}-Rosendahl said, "Weather conditions have settled, 895 00:44:32,366 --> 00:44:34,133 recommend landing." 896 00:44:34,166 --> 00:44:37,133 {\an1}-But he had badly misjudged the weather. 897 00:44:37,166 --> 00:44:41,066 {\an1}Using radar to forecast the weather was still years away. 898 00:44:41,100 --> 00:44:44,766 {\an1}The airbase relied on basic meteorological instruments 899 00:44:44,800 --> 00:44:46,866 and ground observers. 900 00:44:46,900 --> 00:44:49,966 {\an1}By the time the Hindenburg was in position to land, 901 00:44:50,000 --> 00:44:53,233 {\an1}the storm was directly over the base. 902 00:44:53,266 --> 00:44:54,833 {\an1}-There was thunder in the air. 903 00:44:54,866 --> 00:44:56,200 {\an1}There was dampness in the air. 904 00:44:56,233 --> 00:44:57,700 {\an7}There was lightning around. 905 00:44:57,733 --> 00:44:59,300 {\an8}They weren't very good conditions. 906 00:44:59,333 --> 00:45:01,533 {\an7}They shouldn't have landed when they did. 907 00:45:04,233 --> 00:45:06,166 -If the Hindenburg had waited out the storm 908 00:45:06,200 --> 00:45:07,800 away from Lakehurst, 909 00:45:07,833 --> 00:45:09,900 there was still a chance disaster 910 00:45:09,933 --> 00:45:12,966 {\an1}could have been averted. 911 00:45:13,000 --> 00:45:17,200 {\an1}But that would have delayed the return journey back to Europe... 912 00:45:17,233 --> 00:45:19,100 {\an1}which was not acceptable 913 00:45:19,133 --> 00:45:20,800 for brand Hindenburg. 914 00:45:22,800 --> 00:45:26,066 {\an1}-There was enormous pressure to land the ship 915 00:45:26,100 --> 00:45:28,633 and take off as quickly as possible, 916 00:45:28,666 --> 00:45:32,966 {\an1}because it was completely booked with 70 passengers 917 00:45:33,000 --> 00:45:35,000 {\an1}who were headed off to Europe, 918 00:45:35,033 --> 00:45:38,700 which meant the ship was being steered into disaster. 919 00:45:41,500 --> 00:45:43,677 - -The - Hindenburg was the world's first 920 00:45:43,733 --> 00:45:48,033 Regular transatlantic passenger air service. 921 00:45:48,066

contributors to them landing 930 00:46:09,800 --> 00:46:13,866 {\an1}when they did was the pressure that that particular flight back 931 00:46:13,900 --> 00:46:15,733 was a very, very important for them. 932 00:46:15,766 --> 00:46:23,233 {\an8}♪♪♪ 933 00:46:23,266 --> 00:46:24,993 {\an1}-The 934 00:46:23,266 --> 00:46:26,766 was marketed as a luxury passenger service 935 00:46:25,017 -->

obvious reasons, 941 00:46:39,733 --> 00:46:42,566 were very keen to minimize any delay 942 00:46:42,600 --> 00:46:45,533 {\an1}in the functioning of their flagship craft to showcase 943 00:46:45,566

the delayed arrival, the crew would not have had 946 00:46:57,500 --> 00:47:01,100 {\an1}enough time to prepare for the return journey. 947 00:47:01,133 --> 00:47:03,366 {\an7}-The pilots can be under

--> 00:47:09,466 {\an7}they now have to battle against this. 951 00:47:09,500 --> 00:47:12,933 {\an1}-The boss of Lakehurst was under this political pressure, 952 00:47:12,966 --> 00:47:14,127 and the captain of the 953 00:47:14,151 --> 00:47:15,333 Hindenburg 954 00:47:15,366 --> 00:47:20,066 {\an1}was under political pressure, to get on with it. 955 00:47:20,100 --> 00:47:22,933 -This return trip

and luminaries 961 00:47:37,966 --> 00:47:40,800 {\an1}who were expected to travel on the Hindenburg. 962 00:47:40,833 --> 00:47:43,566 {\an8}They were waiting and relying on the fact 963 00:47:43,600 --> 00:47:46,966 {\an8}that this new means of safe transportation 964 00:47:47,000 --> 00:47:50,500 {\an1}would get them back to Europe. 965 00:47:50,533 --> 00:47:52,300 -The coronation of King George VI 966 00:47:52,333 --> 00:47:55,466 is an enormous event on the world stage. 967 00:47:55,500 --> 00:47:56,909 {\an1}It's being covered, of course, by the press 968 00:47:56,933 --> 00:47:58,933 {\an1}in an absolute frenzy, not only because it's 969 00:47:58,966 --> 00:48:01,133 the coronation of a new king in Britain, 970 00:48:01,166 --> 00:48:04,800 {\an1}but also because of the scandal around the abdication 971 00:48:04,833 --> 00:48:06,666 of King George VI's older brother, 972 00:48:06,700 --> 00:48:09,300 {\an1}and his marriage to the divorcée Wallace Simpson, 973

British royal family and in the coronation. 976 00:48:16,366 --> 00:48:18,366 -There must have been enormous pressure 977 00:48:18,400 --> 00:48:22,333 after the flight delays to land the aircraft 978 00:48:22,366 --> 00:48:25,666 {\an1}and to turn it around to get on the way with the next flight, 979 00:48:25,700 --> 00:48:29,100 {\an1}which was highly publicized. 980 00:48:29,133 --> 00:48:32,900

standard airship operational practice, 984 00:48:41,633 --> 00:48:43,766 {\an1}the decision was made to land 985 00:48:43,800 --> 00:48:47,533 {\an1}as the storm overhead grew in intensity. 986 00:48:47,566 --> 00:48:49,266 It was the single biggest mistake 987 00:48:49,300 --> 00:48:51,733 {\an1}leading up to the tragedy. 988 00:48:51,766 --> 00:48:54,166 {\an7}-If you're coming in to land in an atmosphere 989 00:48:54,200 --> 00:48:56,233 {\an7}that is electrically charged, 990 00:48:56,266 --> 00:48:59,233 that represents the potential for a spark 991 00:48:59,266 --> 00:49:02,900 {\an1}and that can be your ignition source for a hydrogen explosion. 992 00:49:02,933 --> 00:49:10,933 {\an8}♪♪♪ 993 00:49:11,233 --> 00:49:13,566 -To decrease the airship's buoyancy, 994 00:49:13,600 --> 00:49:13,600 - the - Hindenburg 995 00:49:13,600 --> 00:49:14,800 Crew 996 00:49:14,833 --> 00:49:18,633 {\an1}began releasing hydrogen from the gasbags. 997 00:49:18,666 --> 00:49:22,300 {\an1}But above them, the gathering storm clouds filled the air 998 00:49:22,333 --> 00:49:25,500 with a deadly electrostatic charge. 999 00:49:25,533 --> 00:49:28,166 -The way in which an airship lands 1000 00:49:28,200 --> 00:49:31,900 is it purposely vents out hydrogen into the air. 1001 00:49:31,933 --> 00:49:35,100 {\an7}If you know that you're venting out hydrogen, though, 1002 00:49:35,133 --> 00:49:39,000 {\an7}you cannot have any possibility of lightning in the sky. 1003 00:49:39,033 --> 00:49:41,533 That's why weather is so critical. 1004 00:49:41,566 --> 00:49:44,666 {\an1}-As the Hindenburg  descended, the crew realized 1005 00:49:44,700 --> 00:49:49,466 {\an1}the airship was no longer level, the tail lower than the bow. 1006 00:49:49,500 --> 00:49:51,166 {\an1}-They felt kind of a jolt. 1007 00:49:51,200 --> 00:49:53,033 Something was off. 1008 00:49:53,066 --> 00:49:54,766 {\an1}The tail of the ship felt heavy, 1009 00:49:54,800 --> 00:49:58,366 {\an1}which means it felt like it had lost some hydrogen. 1010 00:49:58,400 --> 00:50:01,033 It starts to sink. 1011 00:50:01,066 --> 00:50:03,866 {\an1}-Trying to get the airship level, the crew released 1012 00:50:03,900 --> 00:50:06,866 {\an1}more than a ton of water from the ballast tanks, 1013 00:50:06,900 --> 00:50:09,866 {\an1}drenching the ground below. 1014 00:50:09,900 --> 00:50:11,733 {\an1}The airship steadied... 1015 00:50:11,766 --> 00:50:15,266 {\an1}but it was no longer in position to land. 1016 00:50:15,300 --> 00:50:18,100 {\an1}The captain then attempted to steer the Hindenburg 1017 00:50:18,133 --> 00:50:24,100 {\an1}back with a drastic maneuver: a tight turn at full speed. 1018 00:50:24,133 --> 00:50:26,000 -He came in and did that tight turn, 1019 00:50:26,033 --> 00:50:27,176 {\an1}which he shouldn't have done, 1020 00:50:27,200 --> 00:50:28,633 to get the ship down on the ground 1021 00:50:28,666 --> 00:50:30,633 {\an1}and get the passengers swapped over, 1022 00:50:30,666 --> 00:50:34,700 {\an1}to prove that they were running on schedule. 1023 00:50:34,733 --> 00:50:38,266 -At the time, experts believed the sharp turn 1024 00:50:38,300 --> 00:50:41,900 {\an1}started a deadly chain reaction. 1025 00:50:41,933 --> 00:50:43,900 Excessive flexing of the Hindenburg's 1026 00:50:43,933 --> 00:50:46,133 {\an1}internal aluminum frame 1027 00:50:46,166 --> 00:50:47,833 may have caused the botched repair 1028 00:50:47,866 --> 00:50:52,300 {\an1}to the wires surrounding the gasbags to come undone. 1029 00:50:52,333 --> 00:50:53,766 {\an1}-The Commerce Department, 1030 00:50:53,800 --> 00:50:56,866 which investigated the case back in 1937, 1031 00:50:56,900 --> 00:51:01,033 {\an1}believed that a sharp turn in the final landing maneuver 1032 00:51:01,066 --> 00:51:05,633 caused a bracing wire inside the ship to break 1033 00:51:05,666 --> 00:51:09,500 {\an1}and tear into a gasbag. 1034 00:51:09,533 --> 00:51:12,833 {\an1}-But Michael McCarthy suspects the gasbag wasn't ruptured 1035 00:51:12,866 --> 00:51:16,100 {\an1}as a result of the tight turn. 1036 00:51:16,133 --> 00:51:19,333 {\an1}He believes the gasbag was already leaking, 1037 00:51:19,366 --> 00:51:22,700 {\an1}which would explain why the tail of the ship lost buoyancy 1038 00:51:22,733 --> 00:51:25,700 and started to sink. 1039 00:51:25,733 --> 00:51:30,200 {\an1}-What's more likely is that the gasbag had been damaged 1040 00:51:30,233 --> 00:51:31,800 in heavy headwinds, 1041 00:51:31,833 --> 00:51:34,833 {\an1}which delayed the ship for so many hours 1042 00:51:34,866 --> 00:51:40,333 {\an1}and finally created a hydrogen leak inside the top of the ship. 1043 00:51:40,366 --> 00:51:43,700 {\an1}-Even as the Hindenburg  was lined up with the landing mast, 1044 00:51:43,733 --> 00:51:47,166 {\an1}it may have already been leaking hydrogen. 1045 00:51:47,200 --> 00:51:51,966 {\an1}Then, the captain made yet another disastrous decision. 1046 00:51:52,000 --> 00:51:53,433 -There was a high landing technique 1047 00:51:53,466 --> 00:51:55,166 {\an1}and a low landing technique. 1048 00:51:55,200 --> 00:51:58,533 {\an1}But the decision was taken to do the high landing. 1049 00:51:58,566 --> 00:52:02,366 {\an1}That meant that the airship had in its nose two ropes 1050 00:52:02,400 --> 00:52:05,900 {\an1}which dropped for the ground crew to catch hold of. 1051 00:52:05,933 --> 00:52:10,266 -At 7:21 PM, as the rain started to fall, 1052 00:52:10,300 --> 00:52:12,900 {\an1}the first landing rope was lowered. 1053 00:52:12,933 --> 00:52:15,100 {\an1}The ground crew was able to take control of 1054 00:52:15,133 --> 00:52:15,133 - {\an1}the - Hindenburg 1055 00:52:15,133 --> 00:52:16,800 Sooner, 1056 00:52:16,833 --> 00:52:20,700 {\an1}while it was still more than 200 feet overhead. 1057 00:52:20,733 --> 00:52:24,900 {\an1}But it might also have exposed everyone to a new danger. 1058 00:52:24,933 --> 00:52:26,409 {\an1}-All airships, when they fly through the air, 1059 00:52:26,433 --> 00:52:28,766 {\an1}they get a static charge just from the air, 1060 00:52:28,800 --> 00:52:30,333 {\an1}and the ground crew know 1061 00:52:30,366 --> 00:52:32,666 that you don't grab the rope straight away 1062 00:52:32,700 --> 00:52:35,566 because you can get electric shock 1063 00:52:35,600 --> 00:52:39,466 {\an1}as the charge on the surface of the ship travels down. 1064 00:52:39,500 --> 00:52:41,166 -As the Hindenburg came into land, 1065 00:52:41,200 --> 00:52:45,833 {\an1}these landing ropes were wet and so able to conduct electricity. 1066 00:52:45,866 --> 00:52:49,833 {\an1}So you had the metal skeleton of the Hindenburg, 1067 00:52:49,866 --> 00:52:51,733 {\an1}which was then connected to the earth 1068 00:52:51,766 --> 00:52:55,133 via an electrically conductive rope. 1069 00:52:55,166 --> 00:52:57,633 {\an1}-Just four minutes after the first landing ropes 1070 00:52:57,666 --> 00:53:02,566 {\an1}reached the rain-soaked ground, tragedy struck. 1071 00:53:02,600 --> 00:53:04,410 The 1072 00:53:02,600 --> 00:53:06,266 burst into flames. 1073 00:53:04,434 --> 00:53:06,300 Hindenburg 1074 00:53:06,300 --> 00:53:09,833 {\an1}Even today, no one knows whether lightning or a static spark 1075 00:53:09,866 --> 00:53:12,833 {\an1}caused the hydrogen to ignite. 1076 00:53:12,866 --> 00:53:16,100 62 passengers and crewmembers miraculously 1077 00:53:16,133 --> 00:53:18,766 made it safely out of the fireball. 1078 00:53:18,800 --> 00:53:21,400 {\an1}But 36 people were killed... 1079 00:53:21,433 --> 00:53:26,333 {\an1}some instantly, while others died later from their injuries. 1080 00:53:26,366 --> 00:53:28,966 Ernst Lehmann, the pilot on board who hoped 1081 00:53:29,000 --> 00:53:33,700 {\an1}to prevent a potential disaster, died the day after the crash. 1082 00:53:33,733 --> 00:53:39,233 {\an1}-Of the people who died, most of them were killed by gravity. 1083 00:53:39,266 --> 00:53:44,100 {\an1}Because they jumped out when the airship was still up in the air. 1084 00:53:44,133 --> 00:53:46,994 {\an1}-The 1085 00:53:44,133 --> 00:53:49,900 horrible end has shocked the entire world. 1086 00:53:47,018 --> 00:53:49,933 {\an1}Hindenburg's 1087 00:53:49,933 --> 00:53:53,166 {\an1}-The ensuing investigation suggested pilot error 1088 00:53:53,200 --> 00:53:54,733 was to blame. 1089 00:53:54,766 --> 00:53:57,233 {\an1}But today, the newly found maintenance report 1090 00:53:57,266 --> 00:54:00,666 {\an1}and letters suggest the ill-fitting outer cover sealed 1091 00:54:00,700 --> 00:54:02,744 the 1092 00:54:00,700 --> 00:54:04,833 fate long before its final flight. 1093 00:54:02,768 --> 00:54:04,866 Hindenburg's 1094 00:54:04,866 --> 00:54:07,933 {\an1}-The historical record with Zeppelin suggests 1095 00:54:07,966 --> 00:54:12,500 {\an1}that had they been able to fix the fluttering outer cover 1096 00:54:12,533 --> 00:54:14,733 so that the gasbags were no longer damaged, 1097 00:54:14,766 --> 00:54:16,143 {\an1}the 1098 00:54:14,766 --> 00:54:17,566 disaster would never of happened. 1099 00:54:16,167 --> 00:54:21,100 Hindenburg 1100 00:54:21,100 --> 00:54:25,733 {\an1}-No single error caused the events of May 6, 1937, 1101 00:54:25,766 --> 00:54:27,466 {\an1}to happen as they did. 1102 00:54:29,433 --> 00:54:34,000 {\an1}Instead, a raft of fatal flaws led to the destruction 1103 00:54:34,033 --> 00:54:36,433 {\an1}of the world's greatest airship. 1104 00:54:38,733 --> 00:54:43,400 {\an1}-The fact that the thing blew up and was captured by the media 1105 00:54:43,433 --> 00:54:47,466 ended up searing it into our imagination. 1106 00:54:47,500 --> 00:54:50,733 {\an1}-That image of an airship crashing into the ground, 1107 00:54:50,766 --> 00:54:53,033 wreathed in flame, has become iconic... 1108 00:54:53,066 --> 00:54:54,566 {\an1}has become an enduring image, 1109 00:54:54,600 --> 00:54:57,500 I think, of the early 20th century. 1110 00:54:57,533 --> 00:55:02,100 {\an7}-To see that caught on camera, it's quite a devastating moment 1111 00:55:02,133 --> 00:55:04,166 {\an7}that would shock anybody. 1112 00:55:04,200 --> 00:55:07,433 {\an7}There's kind of no coming back from that. 1113 00:55:07,466 --> 00:55:09,933 {\an7}-It had never been seen before... 1114 00:55:09,966 --> 00:55:11,833 {\an7}such a destructive fire, 1115 00:55:11,866 --> 00:55:17,766 {\an7}such a destruction of people, passengers, and an aircraft. 1116 00:55:17,800 --> 00:55:19,633 {\an7}-When the Hindenburg  burst into flames 1117 00:55:19,666 --> 00:55:21,366 {\an7}and fell from the sky, 1118 00:55:21,400 --> 00:55:25,766 {\an7}this brought the death knell to the golden age of the airship. 1119 00:55:25,800 --> 00:55:29,066 {\an8}♪♪♪
