industrial output 101 00:06:50,867 --> 00:06:53,000 that is really a decisive factor 102 00:06:53,066 --> 00:06:55,100 in the outcome of the war. 103 00:06:55,166 --> 00:06:57,867 WALTERS: Suddenly, the U.S. is producing tens of thousands of 104 00:06:57,867 --> 00:07:01,200 warplanes a year, and it's not just vehicles. 105 00:07:01,266 --> 00:07:05,166 There's also a real emphasis on weapons and munitions, 106 00:07:05,266 --> 00:07:08,367 and that is how this site here came to be. 107 00:07:11,166 --> 00:07:13,500 NARRATOR: Construction of the site in the image 108 00:07:13,567 --> 00:07:15,667 begins in August 1940. 109 00:07:19,600 --> 00:07:21,100 By the time it opens, 110 00:07:21,166 --> 00:07:24,767 the mega-factory employs more than 27,000 people. 111 00:07:26,300 --> 00:07:29,400 Many of them are tasked with manufacturing a material 112 00:07:29,467 --> 00:07:34,100 that transformed how war was waged, smokeless gun powder. 113 00:07:34,166 --> 00:07:37,900 Smokeless gunpowder was a revolution for warfare. 114 00:07:38,000 --> 00:07:41,000 Prior to its invention, soldiers regularly 115 00:07:41,100 --> 00:07:42,467 had to try to fire through clouds 116 00:07:42,567 --> 00:07:45,400 of their own smoke to hit targets they could not see. 117 00:07:46,700 --> 00:07:50,367 {\an8}All of a sudden, you couldn't see where that round came from, 118

U.S. factories produce over 121 00:08:02,967 --> 00:08:06,266 41 billion rounds of small arms munitions, 122 00:08:06,367 --> 00:08:10,967 enough to take 20 shots at every person on Earth at the time. 123 00:08:12,700 --> 00:08:16,100 This factory alone manufactures 1 billion pounds 124 00:08:16,166 --> 00:08:19,400 of smokeless gunpowder, for use in anything 125 00:08:19,467 --> 00:08:21,166 from 45-caliber pistols, 126 00:08:21,266 --> 00:08:23,300 to 16-inch naval guns. 127 00:08:24,300 --> 00:08:27,767 This is a war factory on a scale never before seen. 128 00:08:27,767 --> 00:08:32,100 It's truly an incredible feat of manufacturing and production. 129 00:08:33,166 --> 00:08:36,166 ALBERTSON: What you're looking at is the factory that 130 00:08:36,266 --> 00:08:38,767 defeated Nazi Germany and imperial Japan 131 00:08:38,767 --> 00:08:39,900 and fascist Italy 132 00:08:40,000 --> 00:08:41,233 during World War II. 133 00:08:43,100 --> 00:08:46,166 NARRATOR: More than half of the factory workers are women, 134 00:08:46,166 --> 00:08:49,367 many of whom stitch storage bags and pack them with 135 00:08:49,367 --> 00:08:51,467 the explosive powder. 136 00:08:51,467 --> 00:08:54,100 ALBERTSON: The reason you have these structures with hard walls 137 00:08:54,166 --> 00:08:57,367 and soft roofs is that if something detonates, 138 00:08:57,467 --> 00:09:00,500 it goes up rather than out, hopefully killing 139 00:09:00,567 --> 00:09:03,100 as few people as possible in an accident. 140 00:09:04,867 --> 00:09:06,567 NARRATOR: At the end of World War II, 141 00:09:06,667 --> 00:09:09,000 production at the site winds down, 142 00:09:10,967 --> 00:09:13,100 but events then unfold, which see it 143 00:09:13,166 --> 00:09:16,166 play another crucial role in military history. 144 00:09:17,266 --> 00:09:19,667 The United States was facing a very different 145 00:09:19,667 --> 00:09:22,700 kind of enemy, and it roars back into life. 146 00:09:27,467 --> 00:09:30,300 NARRATOR: Coming up, terror in the jungle. 147 00:09:31,300 --> 00:09:34,767 The ambushes absolutely devastate U.S. forces. 148 00:09:35,867 --> 00:09:38,100 NARRATOR: And code of the desert serpent. 149 00:09:39,567 --> 00:09:42,367 These patterns are carved into the ground on 150 00:09:42,467 --> 00:09:44,266 tremendous scales. 151 00:09:53,467 --> 00:09:56,100 NARRATOR: Strange shapes revealed from the skies 152 00:09:56,166 --> 00:09:58,367 have drawn Trevor Albertson 153 00:09:58,367 --> 00:10:01,900 to an abandoned 10,000-acre compound in Indiana. 154 00:10:03,100 --> 00:10:07,200 This is a massive facility used to make the ordnance of war. 155 00:10:08,467 --> 00:10:09,667 RUBEN: During the Second World War, 156 00:10:09,767 --> 00:10:11,800 {\an8}this factory was the largest producer 157 00:10:11,867 --> 00:10:13,867 {\an8}of smokeless powder in the world. 158 00:10:15,000 --> 00:10:17,900 NARRATOR: Military records reveal production at the site 159 00:10:18,000 --> 00:10:20,100 winds down at the end of World War II, 160 00:10:21,900 --> 00:10:24,367 but it goes on to play a role in a very 161 00:10:24,367 --> 00:10:27,667 different kind of conflict on the other side of the world. 162 00:10:29,367 --> 00:10:32,867 CAVELL: The start of the Vietnam conflict is going to see it 163 00:10:32,967 --> 00:10:34,467 come back to life, 164 00:10:34,567 --> 00:10:37,266 {\an8}and massive production will start coming out of 165 00:10:37,266 --> 00:10:38,767 {\an8}this factory once again. 166 00:10:41,367 --> 00:10:43,166 NARRATOR: During the Vietnam War, 167 00:10:43,266 --> 00:10:45,967 the U.S. sends more than 2.5 million 168 00:10:45,967 --> 00:10:48,266 military personnel to Southeast Asia. 169 00:10:53,066 --> 00:10:56,800 But unfamiliar terrain and enemy tactics mean they soon 170 00:10:56,867 --> 00:10:59,867 incur terrible losses at the hands of the Viet Cong. 171 00:10:59,967 --> 00:11:02,667 [explosion blasts] 172 00:11:02,767 --> 00:11:05,367 The Viet Cong preferred guerilla warfare, 173 00:11:05,467 --> 00:11:07,367 hit and run ambushes, 174 00:11:07,367 --> 00:11:10,467 and those absolutely devastate U.S. forces. 175 00:11:12,567 --> 00:11:14,266 The Vietnam War was a very different 176 00:11:14,367 --> 00:11:15,900 type of war from World War II. 177 00:11:16,000 --> 00:11:19,567 So the U.S. shifted the type of weapons that we use. 178 00:11:19,667 --> 00:11:22,200 NARRATOR: Unable to dominate the ground war, 179 00:11:22,266 --> 00:11:25,567 the U.S. turns to the skies, dropping more than 180 00:11:25,567 --> 00:11:28,100 7.5 million tons of bombs, 181 00:11:28,166 --> 00:11:31,900 more than double the total amount used in World War II. 182 00:11:34,400 --> 00:11:37,000 In the jungle, soldiers rely on rockets, 183 00:11:37,100 --> 00:11:40,467 artillery, and mortars to overpower enemy forces. 184 00:11:42,166 --> 00:11:45,000 These weapons allowed the United States to attack from 185 00:11:45,100 --> 00:11:47,867 a greater distance without being attacked themselves, 186 00:11:47,967 --> 00:11:50,967 which negated some of the advantages of guerilla warfare. 187 00:11:54,300 --> 00:11:57,066 NARRATOR: As the conflict escalates, so does production 188 00:11:57,066 --> 00:11:59,100 at the plant in the image, 189 00:11:59,166 --> 00:12:02,467 with almost 20,000 workers contributing to the war effort. 190 00:12:04,000 --> 00:12:05,400 WALTERS: At the height of the Vietnam War, 191 00:12:05,467 --> 00:12:09,867 they are manufacturing eight million mortar charges 192 00:12:09,967 --> 00:12:11,166 every month. 193 00:12:11,266 --> 00:12:13,266 {\an8}That rate of industrial 194 00:12:13,367 --> 00:12:16,266 {\an8}military output is absolutely staggering. 195 00:12:20,600 --> 00:12:24,467 ALBERTSON: It's kind of sobering to think that what came from 196 00:12:24,467 --> 00:12:26,667 here meant a lot of death and destruction for others. 197 00:12:29,300 --> 00:12:31,400 NARRATOR: Despite the U.S. military's 198 00:12:31,467 --> 00:12:32,967 overwhelming firepower, 199 00:12:32,967 --> 00:12:35,567 the war descends into a bloody stalemate. 200 00:12:37,500 --> 00:12:39,667 In an attempt to break the deadlock, 201 00:12:39,767 --> 00:12:42,767 American intelligence operatives authorize a highly 202 00:12:42,867 --> 00:12:44,500 controversial operation, 203 00:12:44,567 --> 00:12:47,800 code named Project Eldest Son. 204 00:12:49,467 --> 00:12:53,066 {\an8}This is really a little known operation in which the U.S. 205 00:12:53,066 --> 00:12:55,667 {\an8}military was able to capture some of 206 00:12:55,767 --> 00:12:57,100 the North Vietnamese ammunition. 207 00:12:57,166 --> 00:13:01,066 They drained out the powder and put in high explosives 208 00:13:01,066 --> 00:13:04,200 and then returned the ammo to the North Vietnamese. 209 00:13:04,266 --> 00:13:08,166 So if they used it, it would explode, killing the user. 210 00:13:09,300 --> 00:13:13,367 The operation also successfully implants this idea 211 00:13:13,467 --> 00:13:15,266 amongst the Viet Cong 212 00:13:15,367 --> 00:13:17,900 that Chinese and Soviet weapons supplies aren't to 213 00:13:18,000 --> 00:13:20,200 be trusted, they're not very well made. 214 00:13:22,200 --> 00:13:24,166 NARRATOR: When the Vietnam War ends, 215 00:13:24,166 --> 00:13:28,000 thousands of workers leave, and the factory falls silent. 216 00:13:31,467 --> 00:13:33,800 But 15 years later, the U.S. government 217 00:13:33,867 --> 00:13:36,667 calls it back into action one final time. 218 00:13:38,100 --> 00:13:39,767 RUBEN: In the late '80s, there were plans to close 219 00:13:39,767 --> 00:13:41,767 this site but it got a last minute reprieve 220 00:13:41,767 --> 00:13:44,000 thanks to the war in Kuwait. 221 00:13:46,567 --> 00:13:49,000 NARRATOR: During the war, the U.S. Navy deploys 222 00:13:49,100 --> 00:13:51,367 two World War II era battleships 223 00:13:51,367 --> 00:13:53,367 to support ground troops in Iraq. 224 00:13:54,467 --> 00:13:56,266 You have the U.S. battleships, 225 00:13:56,367 --> 00:13:58,100 Missouri and Wisconsin . 226 00:13:58,166 --> 00:14:00,166 I mean, they're designed for the Second World War, 227 00:14:00,266 --> 00:14:04,367 and they still need World War II style charges to work. 228 00:14:04,367 --> 00:14:07,300 And so the plant in Indiana went back to manufacturing 229 00:14:07,367 --> 00:14:11,266 the same powder bags that they made during World War II. 230 00:14:11,367 --> 00:14:13,967 NARRATOR: By the time the war has ended, 231 00:14:13,967 --> 00:14:16,967 the factory has produced more than 1.5 million 232 00:14:16,967 --> 00:14:20,100 tons of explosives during its 50-year lifespan. 233 00:14:22,066 --> 00:14:24,567 CAVELL: It's really amazing to think about the fact that 234 00:14:24,567 --> 00:14:27,700 this one factory was producing propellants 235 00:14:27,767 --> 00:14:30,767 for American conflicts from World War II 236 00:14:30,867 --> 00:14:33,000 all the way through to the Gulf War. 237 00:14:36,000 --> 00:14:38,367 NARRATOR: Today, the plant is being demolished, 238 00:14:38,467 --> 00:14:41,367 creating strange patterns visible from space. 239 00:14:43,300 --> 00:14:44,967 The site that helped to defeat 240 00:14:44,967 --> 00:14:48,600 Hitler and Saddam Hussein is being redeveloped, 241 00:14:48,667 --> 00:14:50,700 bringing new life to a town that 242 00:14:50,767 --> 00:14:53,467 brought so much destruction to the world. 243 00:14:53,467 --> 00:14:56,567 WALTERS: When you look at the decaying ruins of 244 00:14:56,567 --> 00:14:58,867 the Indiana Army Ammunition Plant, 245 00:14:58,867 --> 00:15:02,367 they're a real reminder of the incredible military power of 246 00:15:02,467 --> 00:15:04,467 the United States and the many, 247 00:15:04,567 --> 00:15:06,867 many conflicts that shaped the 20th century. 248 00:15:15,166 --> 00:15:18,967 NARRATOR: Coming up, the city being swallowed whole. 249 00:15:18,967 --> 00:15:20,700 What we're looking at was created 250 00:15:20,767 --> 00:15:23,900 by the murderous ego of one man. 251 00:15:24,000 --> 00:15:26,767 NARRATOR: And the strange tale of Rabbit Island. 252 00:15:26,867 --> 00:15:29,367 It's hard to imagine a more stark 253 00:15:29,367 --> 00:15:32,767 contrast than the past of this island... 254 00:15:32,867 --> 00:15:34,100 and its present. 255 00:15:42,767 --> 00:15:47,567 NARRATOR: February 12th, 2021. 256 00:15:49,200 --> 00:15:52,266 Flying over the Ural Mountains in Russia, 257 00:15:52,367 --> 00:15:57,100 a satellite scans a city more than 400 miles below. 258 00:15:57,166 --> 00:15:59,800 WALTERS: What we see here is the typical infrastructure that 259 00:15:59,867 --> 00:16:02,467 {\an8}you're gonna see in any large industrial city, 260 00:16:02,567 --> 00:16:06,000 {\an8}but it appears to have been devoured in places. 261 00:16:08,200 --> 00:16:12,266 KOUROUNIS: Large chunks are just gone, 262 00:16:12,266 --> 00:16:15,767 {\an8}replaced by what looks like water. 263 00:16:18,100 --> 00:16:19,667 NARRATOR: Some of the flooded craters 264 00:16:19,767 --> 00:16:22,000 are over 1,000 feet in diameter. 265 00:16:23,200 --> 00:16:24,667 WALTERS: Throughout the city, we see 266 00:16:24,767 --> 00:16:27,767 scenes of total carnage and destruction. 267 00:16:29,000 --> 00:16:31,567 You've got schools completely vanished, 268 00:16:31,567 --> 00:16:37,900 homes disappeared, and lakes engulfing entire buildings. 269 00:16:41,767 --> 00:16:44,100 NARRATOR: This is Berezniki, 270 00:16:44,166 --> 00:16:47,100 a city of over 150,000 people. 271 00:16:48,400 --> 00:16:51,567 It's become known as the Russian Atlantis. 272 00:16:53,166 --> 00:16:55,400 RODRIGUEZ McROBBIE: Imagine living in a city 273 00:16:55,467 --> 00:16:56,667 where, at any moment, 274 00:16:56,767 --> 00:17:00,266 {\an8}the ground beneath your feet could just give way. 275 00:17:00,266 --> 00:17:02,400 {\an8}Must be terrifying. 276 00:17:04,867 --> 00:17:07,867 NARRATOR: Analysts turn to Berezniki's history for clues. 277 00:17:09,867 --> 00:17:11,266 The unfolding catastrophe, 278 00:17:11,367 --> 00:17:14,467 it turns out, is one a century in the making. 279 00:17:15,767 --> 00:17:17,467 {\an8}Declassified Soviet records 280 00:17:17,567 --> 00:17:19,767 {\an8}tell us that what we're looking at was created by 281 00:17:19,767 --> 00:17:23,467 {\an8}the murderous ego of one man, Joseph Stalin. 282 00:17:25,000 --> 00:17:28,400 NARRATOR: After rising to power in 1928, 283 00:17:28,467 --> 00:17:30,400 Stalin sets a plan in motion 284 00:17:30,467 --> 00:17:32,767 to transform Russia's rural economy. 285 00:17:34,867 --> 00:17:37,400 Known as collectivization, 286 00:17:37,467 --> 00:17:41,266 it will see 25 million farms put under state control. 287 00:17:42,367 --> 00:17:45,000 Stalin basically wants to free up labor 288 00:17:45,100 --> 00:17:47,300 and money to help his country industrialize, 289 00:17:47,367 --> 00:17:50,667 but he also wants to reduce the power of peasant landlords, 290 00:17:50,667 --> 00:17:52,467 whom he despises. 291 00:17:54,800 --> 00:17:56,166 NARRATOR: Over the following years, 292 00:17:56,166 --> 00:17:58,867 over 90 percent of all peasant homesteads 293 00:17:58,867 --> 00:18:03,166 are reorganized into 250,000 collective farms. 294 00:18:04,767 --> 00:18:08,467 Collectivization would see a very large number of people 295 00:18:08,567 --> 00:18:10,600 sent out to collective farms, 296 00:18:10,667 --> 00:18:13,467 {\an8}where they would produce all of the food that the Soviet 297 00:18:13,567 --> 00:18:15,400 {\an8}people needed for survival. 298 00:18:17,266 --> 00:18:21,300 NARRATOR: Sixty million peasants are put to work on 299 00:18:21,367 --> 00:18:24,500 farms that can cover more than 60,000 acres. 300 00:18:25,600 --> 00:18:28,600 If he wants his new farms to feed his entire nation, 301 00:18:28,667 --> 00:18:31,767 Stalin needs vast amounts of fertilizer, and that's what 302 00:18:31,867 --> 00:18:34,567 gives rise to the town in this image. 303 00:18:36,066 --> 00:18:38,100 Berezniki is rich in potash, 304 00:18:38,166 --> 00:18:41,400 which is the potassium-rich salt used in fertilizers. 305 00:18:41,467 --> 00:18:44,000 This would have been essential to Soviet agriculture. 306 00:18:45,567 --> 00:18:49,300 NARRATOR: The potash mine in Berezniki opens in 1932. 307 00:18:50,700 --> 00:18:52,867 It's a place of dread and terror. 308 00:18:54,266 --> 00:18:57,000 Berezniki was one of Russia's gulags. 309 00:18:58,800 --> 00:19:03,100 This forced labor camp sought convicts, from petty criminals 310 00:19:03,166 --> 00:19:04,400 to political prisoners 311 00:19:04,467 --> 00:19:07,500 put to work during the rule of Stalin and, indeed, beyond. 312 00:19:10,300 --> 00:19:13,266 NARRATOR: Berezniki's prisoners are forced to dig tunnels with 313 00:19:13,266 --> 00:19:16,900 bare hands in shifts that can last for 14 hours. 314 00:19:19,367 --> 00:19:20,900 The potash they produce is sent 315 00:19:21,000 --> 00:19:24,266 across Russia to fuel Stalin's agricultural revolution. 316 00:19:27,867 --> 00:19:29,700 KOUROUNIS: Conditions, of course, were terrible. 317 00:19:29,767 --> 00:19:32,400 There was no concern for the health and safety of 318 00:19:32,467 --> 00:19:33,667 these prisoners. 319 00:19:33,667 --> 00:19:37,400 They were worked to near death or to death. 320 00:19:38,800 --> 00:19:40,700 NARRATOR: Despite the prisoners' efforts, 321 00:19:40,767 --> 00:19:44,100 collectivization proves to be a disaster, 322 00:19:44,166 --> 00:19:45,800 and millions die from hunger. 323 00:19:48,266 --> 00:19:51,767 And as the inmates continue to toil in the mine, 324 00:19:51,867 --> 00:19:54,000 the fuse is lit for the disaster 325 00:19:54,066 --> 00:19:56,400 revealed from space. 326 00:19:56,467 --> 00:19:59,467 What Soviet policy required was that labor camps needed to 327 00:19:59,567 --> 00:20:01,867 be set up within marching distance of where 328 00:20:01,867 --> 00:20:03,100 prisoners worked. 329 00:20:03,166 --> 00:20:07,667 So this city was built directly over the potash mine. 330 00:20:09,367 --> 00:20:12,166 The problem is that the walls and supporting pillars 331 00:20:12,166 --> 00:20:15,600 within the mine were carved from the potash itself. 332 00:20:15,667 --> 00:20:17,367 In many places, these underground 333 00:20:17,367 --> 00:20:19,867 voids weren't reinforced with anything. 334 00:20:19,967 --> 00:20:22,667 So it's a recipe for disaster. 335 00:20:24,700 --> 00:20:27,867 NARRATOR: In 2006, a freshwater spring 336 00:20:27,867 --> 00:20:30,667 leaks into the unstable tunnels, 337 00:20:30,667 --> 00:20:33,867 setting off a decades-old geological time bomb. 338 00:20:36,200 --> 00:20:38,600 The water just dissolved the pillars and walls, 339 00:20:38,667 --> 00:20:42,767 leaving nothing to support the heavy earth above. 340 00:20:42,867 --> 00:20:46,567 Now the weight of the city itself was bearing down on 341 00:20:46,567 --> 00:20:48,266 these voids in the earth, 342 00:20:48,266 --> 00:20:51,867 and parts of the town just started to collapse, 343 00:20:51,967 --> 00:20:53,967 caving in on itself. 344 00:20:55,700 --> 00:20:58,467 This really is a case of the horrors of the past coming 345 00:20:58,567 --> 00:21:00,500 back to haunt you, because the prisoners 346 00:21:00,567 --> 00:21:04,367 that were enslaved and forced to toil in those mines right 347 00:21:04,467 --> 00:21:08,700 beneath the city ultimately contributed to its demise. 348 00:21:12,700 --> 00:21:14,967 NARRATOR: The giant water-filled holes forced 349 00:21:14,967 --> 00:21:17,600 12,000 residents to flee their homes. 350 00:21:19,100 --> 00:21:22,367 But for them, the nightmare doesn't end there. 351 00:21:24,367 --> 00:21:27,900 What's been reported is that some of the new buildings that 352 00:21:28,000 --> 00:21:29,467 residents have been moved to 353 00:21:29,467 --> 00:21:32,667 are actually built upon the cemetery of where countless 354 00:21:32,767 --> 00:21:36,066 forced laborers would have been laid to rest. 355 00:21:40,100 --> 00:21:42,567 NARRATOR: Authorities have tried and failed 356 00:21:42,567 --> 00:21:45,066 to stabilize the old gulag mine. 357 00:21:46,100 --> 00:21:48,667 Yet many fear the government is abandoning 358 00:21:48,767 --> 00:21:51,500 the Russian Atlantis to a watery grave. 359 00:21:52,967 --> 00:21:55,100 CERVENY: To put tragedy above tragedy, 360 00:21:55,166 --> 00:21:58,100 {\an8}there's nothing that seems to be being done to 361 00:21:58,166 --> 00:22:01,867 {\an8}stop this mine from collapsing even more in the future. 362 00:22:10,100 --> 00:22:12,767 NARRATOR: Coming up, the Pacific Ocean's 363 00:22:12,867 --> 00:22:15,000 weird vanishing act. 364 00:22:15,100 --> 00:22:18,367 Why would the Japanese make an island disappear? 365 00:22:19,900 --> 00:22:23,100 NARRATOR: And monster worship in the desert. 366 00:22:23,166 --> 00:22:26,166 There's a very thin line sometimes 367 00:22:26,266 --> 00:22:28,266 between fear and religion. 368 00:22:38,367 --> 00:22:40,900 NARRATOR: Spring 2022. 369 00:22:42,900 --> 00:22:44,467 An orbiting camera scans 370 00:22:44,467 --> 00:22:48,000 Okunoshima Island off the coast of Honshu, Japan. 371 00:22:49,600 --> 00:22:50,767 WALTERS: At first, there doesn't seem to 372 00:22:50,767 --> 00:22:52,767 be anything particularly extraordinary 373 00:22:52,867 --> 00:22:54,600 about this island. 374 00:22:54,667 --> 00:22:56,700 MUNOZ: It looks like a lot of 375 00:22:56,767 --> 00:22:59,667 the islands you'd see in the Pacific Ocean. 376 00:23:00,767 --> 00:23:03,500 NARRATOR: However, local records reveal there's something 377 00:23:03,567 --> 00:23:07,367 very strange about this 180-acre landmass. 378 00:23:08,500 --> 00:23:12,166 There was a period of time when this island didn't exist. 379 00:23:14,200 --> 00:23:17,166 Any nautical map, any sort of

MORGAN: They would, for example, take Chinese 458 00:27:23,867 --> 00:27:25,467 prisoners of war, tie them to a post 459 00:27:25,567 --> 00:27:28,100 in the middle of a test range, and then they would 460 00:27:28,166 --> 00:27:32,467 expose these victims to chemical agents. 461 00:27:32,567 --> 00:27:36,667 Another disgustingly common practice was to expose 462 00:27:36,767 --> 00:27:39,767 prisoners to lethal doses of X-rays. 463 00:27:39,867 --> 00:27:42,367 This is completely horrific. 464 00:27:45,000 --> 00:27:47,367 NARRATOR: Some historians estimate that around 465 00:27:47,367 --> 00:27:51,100 600,000 people die at the hands of Unit 731. 466 00:27:53,000 --> 00:27:56,667 They were a peasant people, and the Japanese felt that they 467 00:27:56,667 --> 00:27:59,467 were unworthy of life and they were nothing more 468 00:27:59,567 --> 00:28:00,800 than lab animals. 469 00:28:02,867 --> 00:28:06,166 NARRATOR: During World War II, the island factory uses 470 00:28:06,266 --> 00:28:09,000 Unit 731's so-called research 471 00:28:09,100 --> 00:28:12,400 to produce 6,000 tons of poison gas 472 00:28:12,467 --> 00:28:14,000 and other chemical agents. 473 00:28:15,266 --> 00:28:17,467 The justification for these experiments 474 00:28:17,567 --> 00:28:20,266 was to advance military technology. 475 00:28:20,367 --> 00:28:23,867 It really was atrocities that, nowadays, 476 00:28:23,967 --> 00:28:26,400 would equate to being crimes against humanity. 477 00:28:28,000 --> 00:28:31,867 NARRATOR: Following its surrender in September 1945, 478 00:28:31,867 --> 00:28:33,467 the Japanese government attempts to 479 00:28:33,567 --> 00:28:36,467 cover up Unit 731's brutalities 480 00:28:36,567 --> 00:28:39,600 before abandoning the island. 481 00:28:39,667 --> 00:28:42,667 They escaped from the island with the full knowledge that, 482 00:28:42,767 --> 00:28:44,266 when the Americans get here, 483 00:28:44,367 --> 00:28:46,567 there's going to be hell to pay. 484 00:28:46,667 --> 00:28:49,567 We're going to have to face the music. 485 00:28:51,967 --> 00:28:54,000 NARRATOR: However, in a twist of fate, 486 00:28:54,100 --> 00:28:57,367 many of the murderous scientists escape punishment 487 00:28:57,367 --> 00:28:59,166 for their crimes. 488 00:28:59,166 --> 00:29:01,166 Disgracefully, you actually have 489 00:29:01,166 --> 00:29:03,266 the U.S. government playing an active 490 00:29:03,367 --> 00:29:06,000 role in this cover-up and giving immunity 491 00:29:06,066 --> 00:29:09,600 to some Unit 731 researchers in return 492 00:29:09,667 --> 00:29:11,567 for access to their data. 493 00:29:13,300 --> 00:29:16,500 NARRATOR: Seven decades later, an unlikely legacy of 494 00:29:16,567 --> 00:29:20,100 the Unit 731 experiments remains on the island. 495 00:29:22,500 --> 00:29:26,467 Around 1,000 rabbits have taken up residence here, 496 00:29:26,467 --> 00:29:28,567 rumored to be escapees from its 497 00:29:28,567 --> 00:29:31,100 reign of terror all those years ago. 498 00:29:32,867 --> 00:29:35,867 It's hard to imagine a more stark contrast than 499 00:29:35,967 --> 00:29:39,066 the horrific, grim past of this island 500 00:29:39,066 --> 00:29:40,400 and its present. 501 00:29:47,467 --> 00:29:51,967 NARRATOR: Coming up, the 30-mile-long desert cipher. 502 00:29:51,967 --> 00:29:55,467 NARDI: What we see are cryptic messages, which are 503 00:29:55,467 --> 00:29:58,166 just beyond what we can comprehend at this time. 504 00:29:59,266 --> 00:30:02,100 NARRATOR: And the lagoons of doom. 505 00:30:02,166 --> 00:30:07,867 Their luminous color points to a dark, global story. 506 00:30:16,367 --> 00:30:20,266 NARRATOR: May 21st, 2021. 507 00:30:20,266 --> 00:30:24,767 A satellite flying ove the 77,000-square-mile Thar Desert 508 00:30:24,867 --> 00:30:28,967 in India captures weird patterns in the sands below. 509 00:30:28,967 --> 00:30:32,800 {\an8}What we see from this image 510 00:30:32,867 --> 00:30:37,066 is these lines that appear to be carved into the ground. 511 00:30:38,500 --> 00:30:43,767 {\an8}It's almost like a gigantic toddler with 512 00:30:43,767 --> 00:30:48,667 {\an8}a crayon has carved random patterns into the desert. 513 00:30:53,166 --> 00:30:55,367 NARRATOR: The mystery desert carvings cover 514 00:30:55,367 --> 00:30:58,567 an area equivalent to 38 football fields. 515 00:31:00,066 --> 00:31:02,600 HUNT: It's so remote and isolated, 516 00:31:02,667 --> 00:31:05,000 {\an8}so you have to wonder, 517 00:31:05,100 --> 00:31:06,867 {\an8}what are these things doing here? 518 00:31:09,200 --> 00:31:12,467 NARRATOR: Devin Dennie has a possible answer. 519 00:31:12,467 --> 00:31:16,266 {\an8}One potential theory here is that someone has come to 520 00:31:16,266 --> 00:31:20,100 {\an8}this area to do a seismic survey, looking for uranium. 521 00:31:22,367 --> 00:31:24,467 NARRATOR: India's rapid industrialization 522 00:31:24,567 --> 00:31:25,667 means its energy use 523 00:31:25,667 --> 00:31:27,867 has doubled in the past two decades. 524 00:31:30,400 --> 00:31:33,166 80 percent of the country's power comes from 525 00:31:33,266 --> 00:31:34,867 oil, coal, or wood, 526 00:31:36,100 --> 00:31:38,600 meaning the country is home to 21 527 00:31:38,667 --> 00:31:42,166 of the 30 most polluted cities on Earth. 528 00:31:42,166 --> 00:31:45,000 One of the areas in which India 529 00:31:45,066 --> 00:31:49,000 is expanding its energy sourcing is nuclear. 530 00:31:49,100 --> 00:31:53,166 So you need to prospect for 531 00:31:53,166 --> 00:31:56,667 uranium for this burgeoning nuclear industry. 532 00:31:57,867 --> 00:32:00,100 DENNIE: In order to conduct a seismic survey, 533 00:32:00,166 --> 00:32:04,700 we need to put equipment on the ground, and we need roads 534 00:32:04,767 --> 00:32:07,467 or paths laid out in specific 535 00:32:07,567 --> 00:32:10,567 patterns in order to be able to do this properly. 536 00:32:12,567 --> 00:32:15,166 NARRATOR: Yet when a drone scans the giant patterns in 537 00:32:15,266 --> 00:32:16,367 more detail, 538 00:32:16,467 --> 00:32:19,467 a very different theory emerges. 539 00:32:19,567 --> 00:32:22,567 These patterns really have an organic quality to them. 540 00:32:22,667 --> 00:32:25,300 So that tells me that these are geoglyphs, 541 00:32:25,367 --> 00:32:28,867 patterns intentionally carved into the ground on 542 00:32:28,867 --> 00:32:30,667 tremendous scales, 543 00:32:30,667 --> 00:32:33,000 usually by ancient people. 544 00:32:36,367 --> 00:32:38,767 NARRATOR: Geoglyphs are monumental carvings 545 00:32:38,767 --> 00:32:40,800 designed to be viewed from above. 546 00:32:42,767 --> 00:32:46,166 Their purpose remains unclear, but they appear to be 547 00:32:46,266 --> 00:32:47,800 coded messages, 548 00:32:47,867 --> 00:32:50,767 possibly to gods in the skies. 549 00:32:50,867 --> 00:32:56,100 HUNT: In many cases, geoglyphs are thousands of years old, 550 00:32:56,166 --> 00:33:00,700 and many of these lines scratched in the surface here 551 00:33:00,767 --> 00:33:03,166 imitate a living creature. 552 00:33:04,667 --> 00:33:06,600 NARRATOR: A clue to who created the giant 553 00:33:06,667 --> 00:33:09,767 carvings in India lies across the state border. 554 00:33:12,700 --> 00:33:14,867 KOUROUNIS: Interestingly, not far from where 555 00:33:14,967 --> 00:33:17,100 this satellite image was taken in the nearby state 556 00:33:17,166 --> 00:33:19,500 of Maharashtra, there are some geoglyphs there 557 00:33:19,567 --> 00:33:22,200 that date back to the Stone Age. 558 00:33:23,600 --> 00:33:26,700 NARRATOR: Thousands of geoglyphs and petroglyphs are found 559 00:33:26,767 --> 00:33:28,300 across Maharashtra, 560 00:33:28,367 --> 00:33:31,667 legacies of a civilization that ruled these lands 561 00:33:31,667 --> 00:33:33,367 12,000 years ago. 562 00:33:35,367 --> 00:33:38,700 Many depict predators, such as tigers and sharks. 563 00:33:40,567 --> 00:33:43,000 The society or societies that created 564 00:33:43,100 --> 00:33:45,767 them would have been hunter-gatherers. 565 00:33:47,467 --> 00:33:51,200 HUNT: It's fascinating to see how many of these are of animals 566 00:33:51,266 --> 00:33:52,266 that were feared, 567 00:33:52,266 --> 00:33:54,500 animals that might hunt humans, 568 00:33:54,567 --> 00:33:56,700 animals that posed great risk. 569 00:33:58,567 --> 00:33:59,600 NARRATOR: Some of the carvings in 570 00:33:59,667 --> 00:34:02,000 the desert appear to represent serpents. 571 00:34:04,667 --> 00:34:06,767 Analysts speculate this could shed light on 572 00:34:06,867 --> 00:34:09,266 the belief systems of people who once lived here. 573 00:34:11,000 --> 00:34:12,300 HUNT: In many languages, 574 00:34:12,367 --> 00:34:17,000 the same word for fear is the word for worship. 575 00:34:17,066 --> 00:34:20,266 So there's a very thin line 576 00:34:20,266 --> 00:34:23,200 sometimes between fear and religion. 577 00:34:25,300 --> 00:34:28,867 According to Hindu mythology, the underworld is home to 578 00:34:28,867 --> 00:34:30,367 a race of half-serpent, 579 00:34:30,467 --> 00:34:32,767 half-human beings called nagas. 580 00:34:35,367 --> 00:34:37,367 Snakes in India are also worshiped 581 00:34:37,467 --> 00:34:39,967 as symbols of both death and

mystery. 598 00:35:34,867 --> 00:35:38,000 There are so many unanswered questions. 599 00:35:38,100 --> 00:35:42,200 Were these lines part of some ritual or ceremony? 600 00:35:42,266 --> 00:35:47,467
