How fast do they fly again?
:41:30
- Thirty-one miles an hour.
- Oh, God, there's no way!
:41:34
Yeah, it's slow.
:41:35
- Makes for a really slow aeroplane.
- They're aerodynamically perfect.
:41:39
What's that principle?
The guy that...
:41:43
- Bernoulli.
- Bernoulli.
:41:46
If the wing is curved, airflow moves
faster over the top. It goes farther.
:41:51
Less pressure on top,
ergo lift...
:41:54
...ergo flight.
:41:57
Ergo...
:41:59
Ergo what?
:42:10
Have you turned the gas on, Tom?
:42:13
Yeah, now it's on.
:42:15
Turn it off.
:42:17
Make up your mind.
:42:20
Turn it off until the engine starts.
:42:23
Then turn it back on.
:42:31
This is the kill switch. Clamp it
in your teeth. If you crash...
:42:34
...your jaw relaxes.
You won't get cut up too bad.
:42:39
- Fly on, boys!
- Everybody clear?
