:38:00
	You must've been the pride and joy
of your professors.
:38:02
	You have no idea how they adored me.
:38:06
	Keep that if you like it.
:38:14
	Dr. Lee and all of you gentlemen,
a flight surgeon has been described...
:38:19
	...as a combination of Dutch uncle
and father confessor.
:38:22
	Because he's more
than the pilot's physician...
:38:24
	...he's a judge of their fitness to go on
with the work they've chosen.
:38:27
	For this task,
he must be conscientious...
:38:30
	...and above all, humble,
or he has no business being here.
:38:34
	Tomorrow, we'll take up the effect of
anoxia on the electrocardiogram.
:38:38
	Class dismissed.
:38:40
	Boy, you sure got guts talking back
to him like that.
:38:42
	Surly character, isn't he?
:38:44
	I bet a blood sample would show gall,
bile, with a good dash of sulfuric acid.
:38:53
	Here's the one I'm working on now.
:38:55
	- See that strong bulkhead?
- Yeah.
:38:58
	What are the forces that pull
on a diving pilot when he blacks out?
:39:02
	Between 5 and 10 G.
:39:03
	Between five and 10 times
as strong as the pull of gravity.
:39:06
	- Will it be more with faster ships?
- Not much.
:39:09
	If we lick blackout in our present planes,
the answer will be good a long time.
:39:15
	I've gone over these chamber
equipment lists. They seem okay to me.
:39:19
	Good evening, commander.
:39:27
	Who threw that knife?
:39:29
	I did. Came back pretty fast,
though, didn't it?
:39:31
	If he spent less energy being bitter
and more on flying, we might get action.
:39:35
	Maybe he has a right to be bitter.
:39:37
	He wrecked his heart using himself
as a guinea pig on high-altitude flights.
:39:41
	Now he can't fly anymore and he's stuck
at a laboratory desk day and night.
:39:45
	- Rogers? Used himself as a guinea pig?
- That's right.
:39:49
	He's also the man who doped out
vitamin A for night blindness...
:39:52
	...optically correct goggles...
:39:54
	...and shoulder safety belts
to stop crash injuries.
:39:57
	As a flight surgeon, he's tops.
:39:59
	Wow. I had no idea.
