You don't know. 42 00:03:24,410 --> 00:03:30,530 In less than 24 hours, Corky will test fly the prototype of what could 43 00:03:30,940 --> 00:03:36,380 A viable cargo -carrying airship called the Aeroscraft. 44 00:03:38,420 --> 00:03:43,140 This next -generation vehicle is christened Dragon Dream. 45 00:03:44,980 --> 00:03:50,080 She's absolutely beautiful. I'm really looking forward to taking her out and 46 00:03:50,080 --> 00:03:51,080 what she'll do. 47 00:03:51,140 --> 00:03:53,380 Corky's flown nothing like her before. 48 00:03:55,320 --> 00:03:57,680 Built from 10 ,000 components. 49 00:04:00,330 --> 00:04:06,630 Her revolutionary buoyancy system is filled with $250 ,000 of helium. 50 00:04:07,170 --> 00:04:12,570 Three 300 -horsepower engines thrust her through the sky. 51 00:04:13,390 --> 00:04:19,750 And four ingenious feet work like hovercrafts 52 00:04:19,750 --> 00:04:22,130 to glide across rough terrain. 53 00:04:23,410 --> 00:04:28,850 She's a brand -new concept to ship any type of cargo cheaply. 54 00:04:29,420 --> 00:04:30,600 across the globe. 55 00:04:34,020 --> 00:04:38,420 To me, it's like back to the future. It's really modern space shipping 56 00:04:38,540 --> 00:04:42,800 and yet you can go back over 100 years, and a lot of that technology is right 57 00:04:42,800 --> 00:04:49,180 here. The prototype Dragon Dream weighs 18 tons and is 270 58 00:04:49,180 --> 00:04:50,540 feet long. 59 00:04:50,980 --> 00:04:55,800 But if she passes tomorrow's test flight, a production line could start 60 00:04:55,800 --> 00:04:58,500 airships over three times her size. 61 00:04:59,310 --> 00:05:04,270 920 feet long with lifting capabilities of 500 tons. 62 00:05:04,790 --> 00:05:07,750 They would be the largest aircraft ever made. 63 00:05:09,170 --> 00:05:10,810 This valve is disconnected. 64 00:05:11,290 --> 00:05:16,070 The responsibility for getting this unique airship ready for takeoff falls 65 00:05:16,070 --> 00:05:17,070 one man. 66 00:05:17,550 --> 00:05:20,930 32 -year -old lead engineer Tim Kenny. 67 00:05:28,460 --> 00:05:29,980 Nothing is ever perfect, right? 68 00:05:31,440 --> 00:05:34,780 He has never built anything like Dragon Dream before. 69 00:05:36,700 --> 00:05:41,140 Before I came to Arrow, I was building large robotic machines that shrink wrap 70 00:05:41,140 --> 00:05:46,920 cases of soda. Now, today, we're building a 270 -foot -long airship. You 71 00:05:46,940 --> 00:05:51,020 that pressure can become, you know, extremely overwhelming, especially 72 00:05:51,180 --> 00:05:52,640 you know, kind of your first role. 73 00:05:57,320 --> 00:06:01,920 The man who is applying the maximum pressure is Dragon Dream's inventor. 74 00:06:08,120 --> 00:06:11,740 Company CEO Igor Pasternak. 75 00:06:13,560 --> 00:06:20,200 Born in the Soviet Union, he founded airship company Eros 20 years ago. 76 00:06:20,920 --> 00:06:26,560 He secured $35 million from NASA and the Department of Defense. 77 00:06:27,310 --> 00:06:29,670 to turn his vision into reality. 78 00:06:30,050 --> 00:06:33,550 His reputation is riding on tomorrow's test flight. 79 00:06:34,730 --> 00:06:38,670 It's hard to say what is your personal investment. It's everything. 80 00:06:38,910 --> 00:06:39,769 It's my life. 81 00:06:39,770 --> 00:06:42,190 It's literally my life. 82 00:06:42,450 --> 00:06:44,210 How are we going to do tomorrow? 83 00:06:44,490 --> 00:06:45,950 Oh, we'll be fine for tomorrow. 84 00:06:49,850 --> 00:06:53,590 Airships were once seen as the transport solution of the future. 85 00:06:54,490 --> 00:06:56,810 Until things went terribly wrong. 86 00:07:01,690 --> 00:07:06,250 When the hydrogen -filled Hindenburg exploded in 1937. 87 00:07:08,870 --> 00:07:15,030 Rather than using hydrogen, Dragon Dream is filled with helium, a gas that 88 00:07:15,030 --> 00:07:16,030 doesn't burn. 89 00:07:16,170 --> 00:07:21,470 And Igor's big idea is to reinvent airships to carry cargo. 90 00:07:23,760 --> 00:07:25,300 Some of the people are going to be crazy. 91 00:07:26,320 --> 00:07:29,400 And a lot of them still think they'll be crazy. 92 00:07:30,360 --> 00:07:35,960 And tomorrow probably will be the day when the amount of the people who think 93 00:07:35,960 --> 00:07:38,300 are crazy will be significantly reduced. 94 00:07:38,800 --> 00:07:43,580 Igor hopes his design could use the same amount of fuel to travel from Los 95 00:07:43,580 --> 00:07:48,840 Angeles to Chicago as a regular jetliner would use just to get airborne. 96 00:07:49,200 --> 00:07:50,960 And it needs no runways. 97 00:07:52,170 --> 00:07:54,450 It could take off and land anywhere. 98 00:07:56,550 --> 00:08:03,170 If Dragon Dream works, its low operating costs could mean larger versions win 99 00:08:03,170 --> 00:08:07,150 him a slice of the $5 trillion air cargo industry. 100 00:08:08,850 --> 00:08:14,510 If the test flight fails, his $35 million dream will be over. 101 00:08:15,910 --> 00:08:17,830 All right, let's rock. 102 00:08:22,090 --> 00:08:23,990 It's the day of the big test. 103 00:08:28,690 --> 00:08:32,470 I'm nervous, you know. I'm very nervous. We're trying to control it because I 104 00:08:32,470 --> 00:08:35,210 don't want to be nervous and then everybody else gets nervous. So I'm 105 00:08:35,210 --> 00:08:38,590 be the guy that's not the nervous one, but my nerves are rattled. 106 00:08:38,850 --> 00:08:43,750 Dragon Dream's biggest challenge is withstanding the stresses of her first 107 00:08:43,750 --> 00:08:44,750 test flight. 108 00:08:45,710 --> 00:08:49,010 Building her was a tradeoff between weight and strength. 109 00:08:51,240 --> 00:08:52,680 Weight is your number one enemy. 110 00:08:52,920 --> 00:08:56,700 You can build anything as strong as you want it to be, but it won't float or it 111 00:08:56,700 --> 00:09:00,000 won't take off. On this aircraft, you could build everything as light as 112 00:09:00,000 --> 00:09:03,000 possible, but then it won't take your loads when you look at it from a cargo 113 00:09:03,000 --> 00:09:04,380 standpoint. It would collapse. 114 00:09:05,660 --> 00:09:10,880 Structural failure during the test flight could lead to a disastrous crash 115 00:09:10,880 --> 00:09:12,880 endanger the lives of the pilots. 116 00:09:14,400 --> 00:09:19,380 But Dragon Dream has a secret weapon her designers hope... will stop her 117 00:09:19,380 --> 00:09:20,680 breaking up mid -flight. 118 00:09:21,900 --> 00:09:26,420 The skeleton structure of this aircraft is a combination of unique materials 119 00:09:26,420 --> 00:09:30,980 that we've developed mostly in -house and then combined them in this aircraft 120 00:09:30,980 --> 00:09:33,040 a very unique way to make it fly. 121 00:09:35,760 --> 00:09:41,820 Beneath the airship's skin, 10 ,000 honeycomb aluminum struts make up her 122 00:09:42,240 --> 00:09:46,200 30 ,000 precision -drilled holes make them extra light. 123 00:09:48,360 --> 00:09:51,760 Underneath her metal skeleton is Dragon Dream's backbone. 124 00:09:55,220 --> 00:09:58,460 520 lightweight carbon fiber poles. 125 00:09:59,640 --> 00:10:03,980 Arranged in a structure inspired by a world famous monument. 126 00:10:07,440 --> 00:10:09,160 The Eiffel Tower. 127 00:10:12,840 --> 00:10:16,580 It's an enormous building that's very light for its size. 128 00:10:20,110 --> 00:10:25,070 In fact, it weighs less than the air trapped in a cylinder of the same width 129 00:10:25,070 --> 00:10:26,070 height. 130 00:10:27,230 --> 00:10:32,790 That's because the designers bolted the tower's thin iron struts together in 131 00:10:32,790 --> 00:10:34,610 trusses made from triangles. 132 00:10:36,170 --> 00:10:38,610 The strongest structure in engineering. 133 00:10:41,230 --> 00:10:45,390 Dragon Dream's 200 trusses are even stronger. 134 00:10:48,170 --> 00:10:51,270 96 special nodes join them together. 135 00:10:54,930 --> 00:10:59,210 They move just a few fractions of an inch under stress. 136 00:11:01,310 --> 00:11:05,730 Her rigid carbon fiber backbone can flex without breaking. 137 00:11:06,250 --> 00:11:10,130 And the ship shouldn't snap in half in midair. 138 00:11:16,300 --> 00:11:20,560 These nodes of the structure is kind of like the spine of your back. It's the 139 00:11:20,560 --> 00:11:25,080 cartilage in between each vertebrae that allows those vertebrae to flex together 140 00:11:25,080 --> 00:11:26,620 without fracturing each other. 141 00:11:27,260 --> 00:11:29,360 She's strong and she's flexible. 142 00:11:31,840 --> 00:11:37,300 Dragon Dreams designers have done all they can to prevent a catastrophic mid 143 00:11:37,300 --> 00:11:38,620 -air structural failure. 144 00:11:39,220 --> 00:11:40,220 Am I nervous? 145 00:11:40,540 --> 00:11:42,260 No, I slept good last night. 146 00:11:42,720 --> 00:11:47,380 Now they're just one hour away from finding out if their design holds 147 00:11:47,380 --> 00:11:49,560 to make history. 148 00:11:54,920 --> 00:11:55,640 At 149 00:11:55,640 --> 00:12:03,680 Tustin 150 00:12:03,680 --> 00:12:04,780 Air Base, California. 151 00:12:05,640 --> 00:12:10,820 The revolutionary Dragon Dream airship is just 30 minutes away from her first 152 00:12:10,820 --> 00:12:11,940 ever test flight. 153 00:12:17,120 --> 00:12:21,220 Pilots Corky and Igor perform final flight checks. 154 00:12:26,820 --> 00:12:33,460 Lead engineer Tim 155 00:12:33,460 --> 00:12:34,640 briefs his team. 156 00:12:36,330 --> 00:12:40,910 Today's the big day of all of our hard work. We're going to go out there and 157 00:12:40,910 --> 00:12:43,490 this aircraft really go forward and do some flights. 158 00:12:44,170 --> 00:12:45,810 Watch your feet. Watch for holes. 159 00:12:46,110 --> 00:12:49,170 It's dirty. It's dusty out there. Anybody have any questions? 160 00:12:51,010 --> 00:12:52,250 This is the plan. 161 00:12:53,130 --> 00:12:55,490 Taxi Dragon Dream out the hangar. 162 00:12:56,630 --> 00:12:59,130 Attempt takeoff for the very first time. 163 00:12:59,870 --> 00:13:02,010 Then fly across the airfield. 164 00:13:03,100 --> 00:13:06,640 testing the airship's systems under real flight conditions. 165 00:13:09,300 --> 00:13:13,200 We don't want to hit anything, so we need to be very careful of what's going 166 00:13:13,240 --> 00:13:16,100 on the ropes, keeping up with your crew chief and stuff like that. 167 00:13:17,160 --> 00:13:22,420 The flight's main objective is to trial her experimental buoyancy system. 168 00:13:22,840 --> 00:13:28,080 It's called COSH, Standing for Control of Static Heaviness. 169 00:13:30,090 --> 00:13:32,070 The cost system of this aircraft is revolutionary. 170 00:13:32,450 --> 00:13:36,230 There's not an aircraft in the world that has this system on board. 171 00:13:36,550 --> 00:13:41,050 Traditional airships need ballast to stay on the ground when unloading heavy 172 00:13:41,050 --> 00:13:42,050 cargo. 173 00:13:43,590 --> 00:13:45,270 Dragon Dream is different. 174 00:13:45,590 --> 00:13:51,470 She controls her own heaviness by adjusting the amount of air and helium 175 00:13:51,470 --> 00:13:52,470 the airship. 176 00:13:53,170 --> 00:13:57,010 What we're doing here is we're making a simulation for this aircraft, proving 177 00:13:57,010 --> 00:13:58,410 that that cost system works. 178 00:13:58,810 --> 00:14:02,410 on an open -air flight. What we're doing is we're using a large box here. We're 179 00:14:02,410 --> 00:14:05,770 going to stick that in the cockpit of this aircraft with a simulated payload, 180 00:14:05,870 --> 00:14:07,490 and we're using leaded bags here. 181 00:14:07,850 --> 00:14:11,370 And then we'll take it for a flight, then we'll remove it, and the vehicle 182 00:14:11,370 --> 00:14:13,730 stay stationary on the ground after the flight. 183 00:14:15,530 --> 00:14:19,730 Don't put them all on that end, guys. To prove Dragon Dream works as a cargo 184 00:14:19,730 --> 00:14:25,830 airship, the Kosh system must make her lighter for takeoff and then heavier 185 00:14:25,830 --> 00:14:27,370 unloading the box on the ground. 186 00:14:30,730 --> 00:14:34,990 Don't make me do all the work, guys. Come on. If the airship rises during the 187 00:14:34,990 --> 00:14:38,130 unload, Dragon Dream failed the test. 188 00:14:38,710 --> 00:14:43,090 And $35 million of investment goes down the drain. 189 00:14:43,770 --> 00:14:48,230 I don't want it to fly away, but we've done all the tests inside the hangar and 190 00:14:48,230 --> 00:14:52,270 simulated that, so we should go outside and everything should be okay. 191 00:14:53,270 --> 00:14:55,650 Okay, guys, I'd like to do a flight control check. 192 00:14:56,030 --> 00:14:57,650 Ten minutes to takeoff. 193 00:15:00,720 --> 00:15:01,760 Now it's adjusting up. 194 00:15:02,680 --> 00:15:05,740 Corky and Igor perform final pre -flight check. 195 00:15:09,460 --> 00:15:13,420 Okay, they got 12 gallons, 12 gallons, 12 gallons. We got fuel on all the 196 00:15:14,560 --> 00:15:15,560 Okay, 197 00:15:16,880 --> 00:15:17,880 we're good to go. 198 00:15:25,040 --> 00:15:26,920 There's no turning back down. 199 00:15:36,010 --> 00:15:41,290 The future of aviation history could be transformed if Dragon Dream and her 200 00:15:41,290 --> 00:15:43,370 pilots perform flawlessly. 201 00:15:44,510 --> 00:15:48,830 Just one hitch and the test flight could end in catastrophe. 202 00:15:49,530 --> 00:15:54,850 Five minutes to take. 203 00:15:55,790 --> 00:16:00,250 It's time to test if the Kosh system gets the airship airborne. 204 00:16:10,480 --> 00:16:14,580 Inside are nine massive bags made from a top -secret fabric. 205 00:16:16,340 --> 00:16:20,200 They hold thousands of cubic feet of pressurized helium, 206 00:16:20,460 --> 00:16:26,400 which they can shift in and out of her shell. 207 00:16:28,620 --> 00:16:35,420 At the rear sit vital air ballast bags that can change the 208 00:16:35,420 --> 00:16:36,520 airship's buoyancy. 209 00:16:38,220 --> 00:16:41,040 Their design evolved from marine life. 210 00:16:43,040 --> 00:16:48,780 Fish control their buoyancy through a unique organ, the swim bladder. 211 00:16:49,740 --> 00:16:55,940 As they move up and down in the water, they shift gas from the bloodstream in 212 00:16:55,940 --> 00:17:01,560 and out of the bladder to keep their buoyancy perfectly balanced. 213 00:17:04,240 --> 00:17:07,280 Dragon Dream supersizes this idea. 214 00:17:08,750 --> 00:17:14,829 Each of her four ballast bags holds 900 pounds of air to weigh the ship down and 215 00:17:14,829 --> 00:17:16,050 keep her on the ground. 216 00:17:18,609 --> 00:17:25,069 When Corky jettisons air from the bags and feeds more helium into the shell, 217 00:17:25,250 --> 00:17:31,510 the airship should become lighter than air and take off. 218 00:17:45,040 --> 00:17:49,600 Getting the Kosh system to this make -or -break stage was a big challenge. 219 00:17:54,660 --> 00:17:58,740 Two months ago, the team installed it inside the hangar. 220 00:18:00,720 --> 00:18:04,980 So now you can see that we're pumping in the helium here, and it's starting to 221 00:18:04,980 --> 00:18:07,960 inflate. It probably takes about 30 minutes total. 222 00:18:08,380 --> 00:18:12,140 They threaded each of the nine pressurized helium tanks. 223 00:18:12,780 --> 00:18:17,700 made from a top -secret fabric, through a small gap in the airship's frame. 224 00:18:18,800 --> 00:18:22,760 We've removed one of the structural components, and we'll be installing it 225 00:18:22,760 --> 00:18:23,760 this location. 226 00:18:25,320 --> 00:18:27,420 All right, we're going to lift. You guys are going to push. Ready? 227 00:18:28,980 --> 00:18:30,060 And watch the harness. 228 00:18:34,460 --> 00:18:38,060 We don't want this thing rubbing on any of our sharp edges on the structure. 229 00:18:38,750 --> 00:18:45,070 A rip in one tank could cause the airship to fail midair, possibly 230 00:18:45,070 --> 00:18:46,070 a deadly crash. 231 00:18:46,470 --> 00:18:50,410 There's so many cables in this structure that makes it so difficult for us to 232 00:18:50,410 --> 00:18:53,390 get in there and attach these harnesses to those nodes. 233 00:18:59,730 --> 00:19:03,550 It might not be my life depending on it, but somebody else is going to be in 234 00:19:03,550 --> 00:19:07,370 this aircraft flying, and it's very important everything gets covered. 235 00:19:11,330 --> 00:19:12,330 Today, 236 00:19:14,610 --> 00:19:17,470 the Kosh system is ready to switch on. 237 00:19:17,730 --> 00:19:18,730 There we go. 238 00:19:19,090 --> 00:19:24,750 Yeah. But Tustin Air Base is a challenging location to trial this 239 00:19:24,750 --> 00:19:25,750 technology. 240 00:19:25,950 --> 00:19:29,870 There's only so much he can do under this short little area. Like, if we were 241 00:19:29,870 --> 00:19:32,250 out in the desert and built this aircraft, he'd have lots of room. 242 00:19:32,490 --> 00:19:35,910 The final approach of California's John Wayne Airport. 243 00:19:36,520 --> 00:19:38,600 passes close to the test flight area. 244 00:19:39,760 --> 00:19:46,040 Release helium too fast, and the airship could shoot up into busy airspace. 245 00:19:51,920 --> 00:19:56,060 An uncontrolled takeoff could be disastrous. 246 00:20:01,610 --> 00:20:07,070 Everything now depends on nine pairs of critical valves attached to the helium 247 00:20:07,070 --> 00:20:09,250 tanks inside the airship. 248 00:20:10,530 --> 00:20:17,410 Small pneumatic switches open and close the valve's 249 00:20:17,410 --> 00:20:23,030 flaps to control the flow of gas into her shell. 250 00:20:24,270 --> 00:20:29,370 But release too much helium, and Dragon Dream could ascend too quickly. 251 00:20:30,190 --> 00:20:32,770 and fly into the path of a landing airplane. 252 00:20:36,570 --> 00:20:42,470 One miscalculation now could lead to a catastrophic collision with local air 253 00:20:42,470 --> 00:20:48,410 traffic. Okay, here we go, guys. The lives of the pilots and Dragon Dream's 254 00:20:48,410 --> 00:20:50,870 future now hang in the balance. 255 00:21:05,640 --> 00:21:10,400 Korky and Igor are taking off in the pioneering Dragon Dream airship. 256 00:21:11,060 --> 00:21:15,920 If she successfully completes her first -ever test flight, she could 257 00:21:15,920 --> 00:21:19,520 revolutionize the $5 trillion air cargo industry. 258 00:21:20,460 --> 00:21:25,200 Okay, we're going to regulate just to stabilize here. To leave the ground, her 259 00:21:25,200 --> 00:21:29,440 unique helium tanks must release the right amount of gas. 260 00:21:30,400 --> 00:21:35,740 or the $35 million machine could fly into the path of landing airplanes. 261 00:22:12,090 --> 00:22:14,210 It's a perfect takeoff. 262 00:22:18,530 --> 00:22:25,510 Now Corky and Igor must prove Dragon Dream can fly the full quarter mile 263 00:22:25,510 --> 00:22:27,390 length of the test area. 264 00:22:30,090 --> 00:22:35,430 The airship measures 270 feet long and weighs 18 tons. 265 00:22:36,250 --> 00:22:39,870 She needs powerful engines to thrust her forward. 266 00:22:40,110 --> 00:22:45,270 But conventional engines can create vibrations that could wreck the 267 00:22:45,270 --> 00:22:46,270 frame. 268 00:22:46,670 --> 00:22:53,610 So the team fitted this 269 00:22:53,610 --> 00:22:58,090 airship with three ingenious engines that should smooth out the ride. 270 00:23:03,210 --> 00:23:07,310 Their six cylinders are laid out to eliminate destructive vibrations. 271 00:23:10,870 --> 00:23:13,890 An idea that began in car racing. 272 00:23:17,150 --> 00:23:20,050 Early race cars had a big problem. 273 00:23:22,630 --> 00:23:26,650 In long races, their engines shook themselves apart. 274 00:23:29,970 --> 00:23:31,830 Engineers discovered... 275 00:23:32,110 --> 00:23:37,470 Horizontal pistons moving in opposite directions evened out the forces inside 276 00:23:37,470 --> 00:23:38,470 the engine. 277 00:23:40,890 --> 00:23:46,390 This reduced the engine's vibration and powered the race car to victory. 278 00:23:48,330 --> 00:23:52,190 Dragon Dream takes this technology to the next level. 279 00:23:52,710 --> 00:23:59,390 Her six cylinders, arranged in opposing pairs, produce 300 horsepower. 280 00:24:00,880 --> 00:24:05,900 Their smooth running should reduce the stress on the airship's structure and 281 00:24:05,900 --> 00:24:10,700 keep Dragon Dream powering forward through the air. 282 00:24:18,840 --> 00:24:25,560 But any 283 00:24:25,560 --> 00:24:27,460 engine could go wrong. 284 00:24:29,710 --> 00:24:33,270 As the team discovered four weeks before the test flight. 285 00:24:34,190 --> 00:24:35,190 Adam, easy. 286 00:24:35,530 --> 00:24:36,530 You got the flow speed? 287 00:24:38,310 --> 00:24:39,450 Everybody is ready. 288 00:24:40,030 --> 00:24:43,470 When they performed a routine trial in the hangar. 289 00:24:45,390 --> 00:24:46,470 Servo, right engine. 290 00:24:46,810 --> 00:24:48,810 Right. We're very ready. 291 00:24:49,430 --> 00:24:50,430 Disaster struck. 292 00:25:09,640 --> 00:25:14,480 You guys want to just shut down for a minute, the left engine and hover, and 293 00:25:14,480 --> 00:25:16,480 let's get up there and really check it out. 294 00:25:17,120 --> 00:25:20,420 Fuel flooded the engine and a backfire ignited. 295 00:25:22,040 --> 00:25:25,640 If you're airborne and you get an engine fire, that's a critical, critical, 296 00:25:25,760 --> 00:25:30,080 critical thing. I don't want anything to catch on fire other than my barbecue 297 00:25:30,080 --> 00:25:34,660 ever. When somebody says fire, it's usually something happening that you 298 00:25:34,660 --> 00:25:35,660 want to happen. 299 00:25:37,130 --> 00:25:41,450 A repeat of the hangar fire during today's test flight will be 300 00:25:43,490 --> 00:25:46,490 Dragon Dream's been airborne for 20 minutes. 301 00:25:48,490 --> 00:25:54,510 As Corky ramps up the RPM, there's no sign of trouble. 302 00:25:55,430 --> 00:25:59,370 He can now concentrate on the flight's next critical test. 303 00:26:03,570 --> 00:26:08,070 Steering Dragon Dream using the airship's rudder -like flaps called 304 00:26:08,070 --> 00:26:09,070 surfaces. 305 00:26:11,610 --> 00:26:16,410 Right now he's just playing with the functionality of the control surfaces, 306 00:26:16,410 --> 00:26:19,810 it's changing the bits of the vehicle. That's why it's kind of like all over 307 00:26:19,810 --> 00:26:23,250 place right now because he's just moving the control surface to see what they do 308 00:26:23,250 --> 00:26:24,250 at low speeds. 309 00:26:28,520 --> 00:26:32,760 Corky's command must reach the control surfaces as fast as possible. 310 00:26:33,920 --> 00:26:37,520 They race from his joystick through the ship's nervous system. 311 00:26:38,520 --> 00:26:41,280 820 feet of fiber optic cables. 312 00:26:42,620 --> 00:26:48,260 Traveling at over 120 ,000 miles per second, they reach 10 pneumatic pistons 313 00:26:48,260 --> 00:26:50,460 that move the control surfaces. 314 00:26:51,820 --> 00:26:55,660 It's a system that should give Corky super fast handling. 315 00:27:00,680 --> 00:27:01,900 is responding to his input. 316 00:27:02,260 --> 00:27:04,520 Staying on position, I mean, it looks great. 317 00:27:05,140 --> 00:27:08,220 I'm really happy with what's going on so far. 318 00:27:09,400 --> 00:27:12,800 Dragon Dream's control surfaces keep her straight and level. 319 00:27:13,540 --> 00:27:16,240 But up ahead lies the next big test. 320 00:27:17,660 --> 00:27:20,460 Maneuvering over a 100 -foot gap in a tall fence. 321 00:27:23,120 --> 00:27:25,000 This wind is all over the place right now. 322 00:27:25,260 --> 00:27:27,140 The wind shift to us now, Igor. 323 00:27:28,880 --> 00:27:30,280 It's really squirreling. 324 00:27:33,230 --> 00:27:36,370 Mother Nature is pushing the airship off course. 325 00:27:37,730 --> 00:27:42,050 We're still with wind vectors coming around that hangar, all of these 326 00:27:42,170 --> 00:27:46,430 so the wind changes quite a bit on us. The danger level is rising. 327 00:27:47,450 --> 00:27:51,390 There's a real risk Dragon Dream could collide with the fence. 328 00:27:51,870 --> 00:27:53,690 What's going on in that direction now, buddy? 329 00:27:54,650 --> 00:27:58,010 And her test flight ends in disaster. 330 00:28:05,260 --> 00:28:12,220 At Tustin Air Base, California, $35 million airship Dragon Dream is half an 331 00:28:12,220 --> 00:28:14,120 into her first ever test flight. 332 00:28:14,840 --> 00:28:20,820 If successful, this prototype could spawn a new generation of airships that 333 00:28:20,820 --> 00:28:25,080 promises to reshape the $5 trillion air cargo industry. 334 00:28:27,920 --> 00:28:30,180 We're going to go, yep, something like that. 335 00:28:31,240 --> 00:28:37,780 Pilots Corky and Igor must now prove Dragon Dream's untested steering system 336 00:28:37,780 --> 00:28:41,580 maneuver her over a 100 -foot gap in a fence up ahead. 337 00:28:46,240 --> 00:28:52,420 Dragon Dream's designers have equipped the rear of the airship with a propeller 338 00:28:52,420 --> 00:28:56,980 framed by two retractable shrouds. 339 00:28:58,320 --> 00:29:01,880 The design... should steer the airship from the back. 340 00:29:02,720 --> 00:29:07,120 It's an ingenious idea that evolved from rockets. 341 00:29:09,280 --> 00:29:12,360 Pioneering rocket engineers faced a major problem. 342 00:29:13,320 --> 00:29:17,620 Too many of their designs lost control during the slow takeoff. 343 00:29:20,320 --> 00:29:24,400 In the late 1940s, they tried something new. 344 00:29:25,300 --> 00:29:28,280 Installing a movable nozzle to direct thrust. 345 00:29:28,990 --> 00:29:31,410 and a gyroscope in the rocket's nose. 346 00:29:32,890 --> 00:29:38,310 If the gyro sensed the rocket leaning one way, it positioned the nozzle the 347 00:29:38,310 --> 00:29:44,230 other way to shift the engine's thrust and push the rocket back on course. 348 00:29:45,990 --> 00:29:50,550 Dragon Dream uses this rocket steering concept in a new way. 349 00:29:51,770 --> 00:29:56,850 Corky can move the airship's shrouds to redirect the thrust from side to side. 350 00:29:59,310 --> 00:30:03,370 and rotate them to nudge the tail up or down. 351 00:30:04,570 --> 00:30:07,710 He should be able to turn the airship on a dime. 352 00:30:12,230 --> 00:30:19,210 Lead engineer Tim Kenny is worried about 353 00:30:19,210 --> 00:30:22,270 how the steering system will work under flight conditions. 354 00:30:24,630 --> 00:30:27,930 This is all new.
