Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:01,580 --> 00:00:04,260
A new breed of super machines is
evolving.
2
00:00:05,820 --> 00:00:08,140
Bigger. Faster.
3
00:00:09,280 --> 00:00:10,280
Smarter.
4
00:00:11,000 --> 00:00:17,460
Built to tackle near impossible feats.
Among them, a next generation airship.
5
00:00:17,820 --> 00:00:19,900
Okay, we're ready to start engines in
the cockpit.
6
00:00:20,700 --> 00:00:27,700
Will this experimental floating giant
forever change air transportation?
7
00:00:29,260 --> 00:00:34,600
The first time we've built a ship like
this ever. Or will it crash and burn?
8
00:00:35,000 --> 00:00:36,000
Fire, fire.
9
00:00:37,640 --> 00:00:44,200
We'll blow
10
00:00:44,200 --> 00:00:50,400
this $35 million beast apart to discover
technological secrets
11
00:00:50,400 --> 00:00:52,540
that overcome the impossible.
12
00:00:56,110 --> 00:01:02,250
A revolutionary helium buoyancy system
that can lift nine SUVs.
13
00:01:03,050 --> 00:01:08,030
Engine with the combined power of a race
car.
14
00:01:08,430 --> 00:01:12,910
Landing beam to touch down anywhere in
the world.
15
00:01:14,590 --> 00:01:20,750
We'll reveal how this extraordinary
airship evolved to rise above
16
00:01:20,750 --> 00:01:22,970
all other machines.
17
00:01:34,860 --> 00:01:40,620
Tustin Air Base, 40 miles southeast of
downtown Los Angeles.
18
00:01:42,980 --> 00:01:44,580
Go, it's okay, let it go.
19
00:01:45,560 --> 00:01:51,600
Inside this former military hangar,
engineers make adjustments to a
20
00:01:51,600 --> 00:01:52,740
flying machine.
21
00:01:53,620 --> 00:01:58,220
Okay, I'm ready. Sounds good, guys. A
revolutionary airship.
22
00:01:59,280 --> 00:02:03,740
Her design could usher in a new
generation of cargo vehicles.
23
00:02:04,830 --> 00:02:10,130
Carrying everything from food and
military hardware to humanitarian aid
24
00:02:10,130 --> 00:02:11,130
cars.
25
00:02:11,750 --> 00:02:15,670
For less money than any airplane in
existence.
26
00:02:16,990 --> 00:02:19,330
John, we're going to go for another
test.
27
00:02:19,790 --> 00:02:20,790
Looks good.
28
00:02:20,990 --> 00:02:25,850
In 24 hours time, she will make her
first ever test flight.
29
00:02:26,290 --> 00:02:28,230
Three, two, one.
30
00:02:29,770 --> 00:02:32,970
This is the daredevil pilot who will fly
her.
31
00:02:35,280 --> 00:02:37,880
I'm kind of a helium head, so to speak.
32
00:02:41,060 --> 00:02:46,440
Corky Bellinger, one of around only 50
blimp pilots worldwide.
33
00:02:47,160 --> 00:02:52,500
He's clocked up more than 15 ,000 hours
flight time in airships.
34
00:02:53,320 --> 00:02:58,440
After flying for 40 -plus years just in
airships alone, this is the pinnacle of
35
00:02:58,440 --> 00:02:59,339
my career.
36
00:02:59,340 --> 00:03:02,020
I'm really looking forward to this and
making it work.
37
00:03:02,410 --> 00:03:07,630
The future of lighter than air is
resting on what we're doing here.
38
00:03:08,330 --> 00:03:12,430
In the next 20 years, I think that
you're going to be able to look up and
39
00:03:12,430 --> 00:03:15,990
airship just as readily as you look up
now and you see an airplane.
40
00:03:17,390 --> 00:03:21,350
I guess in a sense, when you get into
something like this, you're laying your
41
00:03:21,350 --> 00:03:23,350
butt on the line. 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. I mean, every time we
do something with it, it's new.
355
00:30:28,480 --> 00:30:32,620
And we're learning things as it goes.
You know, the first time we've built a
356
00:30:32,620 --> 00:30:33,640
ship like this ever.
357
00:30:33,960 --> 00:30:39,300
The only chance the teams had to trial
the experimental steering system was
358
00:30:39,300 --> 00:30:40,600
inside the hangar.
359
00:30:41,920 --> 00:30:44,160
Just a month before the test flight.
360
00:31:15,020 --> 00:31:18,860
The system took six months and $30 ,000
to build.
361
00:32:08,240 --> 00:32:14,340
Hangar tests were a success, but no one
knows how the system will work during
362
00:32:14,340 --> 00:32:15,540
today's test flight.
363
00:32:17,460 --> 00:32:20,020
As Dragon 3 approaches the fence.
364
00:32:22,420 --> 00:32:25,160
If I go from here, I don't have to drag
the ropes over the fence.
365
00:32:31,080 --> 00:32:36,740
We got some safety guys on the line just
in case it does something we don't want
366
00:32:36,740 --> 00:32:37,339
it to.
367
00:32:37,340 --> 00:32:40,960
So what we're going to do is kind of let
the line completely slack.
368
00:32:41,160 --> 00:32:44,700
We'll still have guys close by, need it
if we want to, you know.
369
00:32:45,200 --> 00:32:48,820
This is the most dangerous stage of the
test flight so far.
370
00:32:50,340 --> 00:32:54,420
Innovative steering systems can fail
with disastrous results.
371
00:32:56,900 --> 00:32:58,520
Virginia 1922.
372
00:33:00,840 --> 00:33:05,740
U .S. Army airship Roma suffered a
malfunction with its steering mechanism.
373
00:33:08,200 --> 00:33:10,480
The airship drifted towards the ground.
374
00:33:12,040 --> 00:33:17,880
It hit high -voltage power lines and
exploded.
375
00:33:19,320 --> 00:33:22,740
34 passengers and crew died instantly.
376
00:33:26,660 --> 00:33:33,140
On their approach to the fence, Corky
and Eagle attempt a gentle turn.
377
00:33:42,570 --> 00:33:45,990
Tim watches nervously as the airship
changes position.
378
00:33:48,070 --> 00:33:50,570
The wind just shifted 90 degrees on us.
379
00:33:51,010 --> 00:33:53,750
We're not going to be able to go over
that fancy eagle with this wind.
380
00:33:54,790 --> 00:33:57,710
Strong gusts suddenly push the airship
offline.
381
00:33:59,470 --> 00:34:01,110
Careful, guys. We're drifting hard.
382
00:34:02,750 --> 00:34:04,990
Overpowering the experimental steering
system.
383
00:34:17,520 --> 00:34:20,940
And putting Dragon Dream on a collision
course with the fence.
384
00:34:23,080 --> 00:34:23,840
At
385
00:34:23,840 --> 00:34:30,780
Tustin Air Base,
386
00:34:30,960 --> 00:34:36,040
California, the revolutionary Dragon
Dream airship is in trouble.
387
00:34:37,100 --> 00:34:42,920
Strong winds are pushing her straight
towards a tall fence.
388
00:35:11,150 --> 00:35:14,530
pilots Corky and Igor face a make or
break decision.
389
00:35:17,090 --> 00:35:23,850
Crash land the $35 million airship or
power over the seven foot tall fence
390
00:35:23,850 --> 00:35:26,070
and set down on the other side.
391
00:35:26,410 --> 00:35:27,590
I don't have a choice, guys.
392
00:35:27,850 --> 00:35:29,250
I got no choice.
393
00:35:46,440 --> 00:35:49,680
The airship scrapes over the fence with
just feet to spare.
394
00:36:00,180 --> 00:36:01,180
Touchdown.
395
00:36:06,340 --> 00:36:09,520
It's a relief for lead engineer Tim
Kenney.
396
00:36:09,780 --> 00:36:11,900
Oh, that ship goes six feet off the
fence.
397
00:36:12,120 --> 00:36:13,980
A couple times right there was pretty...
398
00:36:16,880 --> 00:36:19,100
It's time for the next critical test.
399
00:36:19,760 --> 00:36:26,760
The airship must taxi back to the hangar
to prove it can operate in areas with
400
00:36:26,760 --> 00:36:27,940
rough landing zones.
401
00:36:28,400 --> 00:36:29,560
I'm on a taxi, ma 'am.
402
00:36:30,380 --> 00:36:35,540
Corky and Eagle are relying on the
airship's unique feet for a smooth ride.
403
00:36:38,920 --> 00:36:44,840
Each one is 26 feet long, almost the
length of two SUVs.
404
00:36:47,470 --> 00:36:52,410
They're designed to reduce friction
between the airship and the ground by
405
00:36:52,410 --> 00:36:54,450
floating on a cushion of air.
406
00:36:57,730 --> 00:37:03,410
They owe their origin to a
groundbreaking invention from the 1950s.
407
00:37:06,330 --> 00:37:11,870
A propeller, an engine, and a boat with
rubber wrapped around it.
408
00:37:14,120 --> 00:37:17,300
The propeller pushed air down into the
rubber skirting.
409
00:37:18,300 --> 00:37:25,120
It was the world's first commercial
hovercraft and inspired the Dragon
410
00:37:25,120 --> 00:37:26,120
feet.
411
00:37:26,860 --> 00:37:30,960
The fans in each foot spin at 3 ,400
RPM.
412
00:37:32,920 --> 00:37:39,000
They push air into a soft plastic skirt,
forming a thin cushion of air directly
413
00:37:39,000 --> 00:37:40,160
under the airship.
414
00:37:41,340 --> 00:37:47,350
These mini hovercrafts should allow
Dragon Dream to glide across the
415
00:37:47,350 --> 00:37:48,350
terrain.
416
00:37:53,870 --> 00:37:54,550
The
417
00:37:54,550 --> 00:38:09,370
airship
418
00:38:09,370 --> 00:38:11,150
skims across the uneven terrain.
419
00:38:12,170 --> 00:38:14,670
and comes to a halt outside the hangar.
420
00:38:16,170 --> 00:38:22,650
Only the final and most important
challenge remains,
421
00:38:23,270 --> 00:38:26,250
unloading the 500 -pound cargo crate.
422
00:38:30,390 --> 00:38:37,290
To prove she's a viable cargo
transporter, her buoyancy system must
423
00:38:37,290 --> 00:38:39,250
keep her grounded during the unload.
424
00:38:41,930 --> 00:38:45,530
If she floats up into the air, she'll
fail the test.
425
00:38:48,090 --> 00:38:50,350
And put the ground crew in danger.
426
00:38:54,410 --> 00:38:59,110
Like U .S. Navy airship USS Akron did in
1932.
427
00:39:01,330 --> 00:39:03,810
Sailors secured her as she came in to
land.
428
00:39:05,610 --> 00:39:09,890
Warmed by the sun, the airship's helium
became more buoyant.
429
00:39:10,320 --> 00:39:13,020
Akron began to ascend out of control.
430
00:39:14,180 --> 00:39:19,520
Three sailors failed to let go of the
landing rope and were pulled into the
431
00:39:19,520 --> 00:39:20,800
as the airship rose.
432
00:39:23,680 --> 00:39:25,900
Two plunged to their deaths.
433
00:39:26,660 --> 00:39:29,840
The other was saved in a daring mid -air
rescue.
434
00:39:33,040 --> 00:39:37,240
If Dragon Dream's revolutionary buoyancy
system fails today,
435
00:39:38,160 --> 00:39:42,000
some of the ground crew could be in
danger of a similar fate.
436
00:39:47,180 --> 00:39:49,200
This is how it should work.
437
00:39:53,140 --> 00:39:59,840
Compressors inside the airship should
suck helium from its shell into nine
438
00:39:59,840 --> 00:40:00,840
-pressure tanks.
439
00:40:03,480 --> 00:40:05,080
At the same time,
440
00:40:07,280 --> 00:40:11,460
Fans help channel hundreds of pounds of
air into ballast bags.
441
00:40:14,360 --> 00:40:20,960
This should make the airship heavy
enough to stay grounded when the crew
442
00:40:20,960 --> 00:40:22,560
unload the cargo crate.
443
00:40:24,360 --> 00:40:26,420
Make sure all of these keys are enabled.
444
00:40:27,660 --> 00:40:33,040
Pass this test and Dragon Dream has a
future as a heavy cargo transporter.
445
00:40:38,140 --> 00:40:43,540
Any malfunctions and the airship will
lift off the ground, possibly hauling
446
00:40:43,540 --> 00:40:45,140
ground crew into the air.
447
00:41:09,640 --> 00:41:11,120
The box is out.
448
00:41:11,880 --> 00:41:15,080
Kosh keeps the airship rock solid on the
ground.
449
00:41:19,160 --> 00:41:20,520
Absolutely perfect.
450
00:41:22,480 --> 00:41:23,760
Yeah, give me a fight.
451
00:41:24,220 --> 00:41:25,960
The mission is a success.
452
00:41:27,640 --> 00:41:29,680
Okay, let's put it in the bar.
453
00:41:54,080 --> 00:41:55,280
Absolutely fantastic.
454
00:41:57,920 --> 00:42:00,080
That was great. It was absolutely great.
455
00:42:00,340 --> 00:42:04,940
And the cockpit had no glitches at all.
No red lights. Everything was green. It
456
00:42:04,940 --> 00:42:05,940
was perfect.
457
00:42:06,120 --> 00:42:09,980
The test flight over.
458
00:42:10,820 --> 00:42:15,300
Lead engineer Tim Kenny sets his sights
on the next challenge.
459
00:42:16,120 --> 00:42:17,280
Should we go higher?
460
00:42:17,720 --> 00:42:19,160
Absolutely. Can we go farther?
461
00:42:19,380 --> 00:42:23,780
Absolutely. I want to keep flying and
keep going and keep going. You know, I
462
00:42:23,780 --> 00:42:27,840
want to see it fly over people's homes
and actually, you know, people see it
463
00:42:27,840 --> 00:42:31,780
real. The test flight is a milestone in
aviation history.
464
00:42:33,160 --> 00:42:38,640
Production could now start on larger
versions of Dragon Dream that will carry
465
00:42:38,640 --> 00:42:44,560
everything from humanitarian aid to
military equipment all over the world.
466
00:42:47,269 --> 00:42:51,390
Everything today was a success. It
really, really was. I can't begin to
467
00:42:51,390 --> 00:42:52,730
how happy I am. I'm thrilled.
468
00:42:57,530 --> 00:43:01,090
I'm going to go home for a couple of
weeks, play a little golf, get on the
469
00:43:01,230 --> 00:43:06,050
and just kind of think about relaxing a
little bit. And then after a couple of
470
00:43:06,050 --> 00:43:07,970
weeks, come back and get into it again.
471
00:43:08,460 --> 00:43:10,220
You can't put a fork in me just yet.
472
00:43:10,540 --> 00:43:16,500
Dragon Dream could be the revolutionary
cargo airship of the 21st century.
473
00:43:20,980 --> 00:43:25,340
It's thanks to steering inspired by
rockets.
474
00:43:30,340 --> 00:43:32,880
The work like hovercraft.
475
00:43:36,010 --> 00:43:39,050
Super reliable 300 horsepower engines.
476
00:43:41,890 --> 00:43:44,850
A revolutionary buoyancy system.
477
00:43:47,430 --> 00:43:50,730
And a light, tough carbon fiber
skeleton.
478
00:43:51,330 --> 00:43:56,550
But this airship has evolved to rise
above all other machines.
