- The beginning of the moon landing...
- Man's first step...
:05:06
...being watched by all the world,
united in a way never before possible...
:05:09
It's a groovy trip, but there are
more important things to do first.
:05:12
It will be a revelation
to all mankind...
:05:15
that the universe
and the creation...
:05:18
is so much greater
than anybody ever realized.
:05:23
Just how do you
land on the moon?
:05:26
That is the task at hand today
for the crew of Apollo 11...
:05:30
and it has been the subject and
preoccupation of a great many people...
:05:34
for a great many months...
:05:36
including Jay Honeycutt,
NASA flight simulation supervisor.
:05:39
Tell me, Jay.
:05:41
The simulation facilities
are all computer driven...
:05:45
but how lifelike
are they really?
:05:47
All the problems
we create in a simulator...
:05:50
can happen in the flight...
:05:52
and the crew sees the moon
as it would be outside the window.
:05:57
The simulator performs
just as the LEM would.
:05:59
- The lunar module.
- Right.
: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...
