:06:01
Under whatever circumstances
we can create.
:06:03
So, if things go south
in the simulator...
:06:07
The crew has to take whatever steps
necessary to save the mission.
:06:10
Or, theoretically, their lives.
:06:13
Yes.
:06:15
The landing begins at 50,000 feet
above the lunar surface...
:06:19
when Armstrong and Aldrin
are given the go for power descent.
:06:23
At 46,000 feet Armstrong
will roll the LEM onto its back.
:06:28
At 7,500 feet the computer's
final landing program...
:06:32
P-64... will commence...
:06:34
pitching the LEM forward from face up
to about 30 degrees from vertical...
:06:39
allowing Armstrong and Aldrin
to see the lunar surface.
:06:43
As they approach the landing site
the most crucial information will be...
:06:47
altitude, rate of descent,
horizontal velocity...
:06:50
and propellant remaining.
:06:51
If they get below
about 80 seconds of fuel remaining...
:06:54
the "quantity" light
will illuminate.
:06:56
At that point they've got 60 seconds
to decide whether or not to land...
:07:00
leaving them
20 seconds of fuel...
:07:02
to either get down
or level off their descent and abort.
:07:05
At six feet,
if all goes well...
:07:08
probes extending from the landing gear
will touch the surface...
:07:11
and they will get
the "contact" light.
:07:13
Armstrong will then shut off
the descent engine and they will drop...
:07:16
gently to the surface...
:07:18
and mankind will never be
the same again, blah, blah, blah.
:07:22
The landing is, by far,
the most difficult part of this mission.
:07:27
Getting to the moon isn't easy.
Neither is walking on it.
:07:30
Or blasting off, docking
and going home.
:07:32
But the landing, that's the thing:
One shot, no second approaches...
:07:36
a quarter of a million miles
from home.
:07:39
For the next three months...
:07:42
we will do everything in our power
to see that these men land safely...
:07:46
which means, for the next three months
we must do everything in our power...
:07:49
to kill them.
:07:52
So, how many times have you
"killed" the crew of Apollo 11?
:07:58
- Well, many times.
- Hundreds of times? Thousands?
