okay let's go there capcom on the hot

2
00:00:07,030 --> 00:00:04,240
fire okay all flight controllers going

3
00:00:10,709 --> 00:00:07,040

4
00:00:13,589 --> 00:00:10,719
okay retro go final go go control go

5
00:00:16,470 --> 00:00:13,599

go capcom go for unknocking

7
00:00:22,390 --> 00:00:19,039
armstrong aldrin and collins arrived at

8
00:00:24,790 --> 00:00:22,400
the moon on saturday july 19th when we

9
00:00:27,429 --> 00:00:24,800
did get close and we rolled down and saw

10
00:00:29,910 --> 00:00:27,439
it for the first time it was uh it was a

11
00:00:32,050 --> 00:00:29,920
revelation it was gigantic

12
00:00:34,870 --> 00:00:32,060
it filled our entire window

13
00:00:37,430 --> 00:00:34,880

14
00:00:40,389 --> 00:00:37,440
the next day sunday july 20th was

15
00:00:43,270 --> 00:00:40,399
landing day in a lot of anticipation we

16
00:00:45,910 --> 00:00:43,280
finally come to the day the moment

17
00:00:47,910 --> 00:00:45,920
that this is about to commence

18
00:00:50,229 --> 00:00:47,920
landing on the moon was absolutely the

19
00:00:53,110 --> 00:00:50,239
most difficult piece of any apollo

20
00:00:54,790 --> 00:00:53,120
mission okay think about it as a

21
00:00:58,069 --> 00:00:54,800
controlled fall

22
00:01:00,709 --> 00:00:58,079
out of lunar orbit the problem is in

23
00:01:03,430 --> 00:01:00,719
this controlled fall out of orbit

24
00:01:06,310 --> 00:01:03,440
you only have enough fuel for one try

25
00:01:07,990 --> 00:01:06,320
capcom or go for landing altitude 4200

26
00:01:10,550 --> 00:01:08,000
for landing over

27
00:01:12,270 --> 00:01:10,560
the trajectory had been wrong we had

28
00:01:15,270 --> 00:01:12,280
they were targeted into this

29
00:01:18,230 --> 00:01:15,280
inhospitable place then it had to fly

30
00:01:21,830 --> 00:01:18,240
over this area at a high forward

31
00:01:24,310 --> 00:01:21,840
velocity then pitch up to slow down so

32
00:01:26,630 --> 00:01:24,320
that kill that forward velocity and then

33
00:01:29,590 --> 00:01:26,640
start down like a helicopter

34
00:01:32,230 --> 00:01:29,600
so now we're critical fuel state

35
00:01:35,350 --> 00:01:32,240
and that's why the 60-second call was

36
00:01:37,990 --> 00:01:35,360
given and then the 30-second call then i

37
00:01:41,590 --> 00:01:38,000
really got nervous was calling out 25

38
00:01:42,550 --> 00:01:41,600
seconds of fuel left and then 20 seconds

39
00:01:45,190 --> 00:01:42,560
of view

40
00:01:48,469 --> 00:01:45,200
oh geez

41
00:01:50,230 --> 00:01:48,479
okay engine stop apa at a deep end boat

42
00:01:51,749 --> 00:01:50,240
control both auto definition command

43
00:01:52,570 --> 00:01:51,759
override off

44
00:02:01,270 --> 00:01:52,580
engine arm off

45
00:02:03,510 --> 00:02:01,280

roger twain tranquility we copy on the

49

00:02:12,470 --> 00:02:10,800
turn blue we're breathing again thanks a

51
00:02:14,390 --> 00:02:12,480
lot

52
00:02:16,550 --> 00:02:14,400
the landing to me was a great

53
00:02:17,830 --> 00:02:16,560
celebration the nation was almost

54
00:02:19,910 --> 00:02:17,840
euphoric

55
00:02:21,510 --> 00:02:19,920
well it proved that

56
00:02:22,710 --> 00:02:21,520
the united states

57
00:02:25,350 --> 00:02:22,720
could

58
00:02:30,970 --> 00:02:25,360
accomplish tremendous goals if they work
