The rise of Starliner and a new era of human
spaceflight.

3
00:00:17,700 --> 00:00:25,630
Launch Commentator: Now ten seconds into flight.

4
00:00:25,630 --> 00:00:30,949
Vehicle’s begun the pitch-over program.

5
00:00:30,949 --> 00:00:36,070
Body rate responses look good.

6
00:00:36,070 --> 00:00:40,170
Now 15 seconds in.

7
00:00:40,170 --> 00:00:41,199
(Inaudible).

8
00:00:41,199 --> 00:00:46,329
Now 26 seconds into flight.

9
00:00:46,329 --> 00:00:49,440
RD-180 now throttling down to partial thrust,
as expected.

10
00:00:49,440 --> 00:00:50,440
Engine response looks good.

11
00:00:50,440 --> 00:00:51,440
Now 38 seconds in.

12
00:00:51,440 --> 00:00:58,180
RD-180 engine operating parameters continue
to look good.

13
00:00:58,180 --> 00:01:04,769
Vehicle is now passing through Max Q – maximum
dynamic pressure.

14
00:01:04,769 --> 00:01:07,140
Chamber pressures on both SRBs continue to
look good.

15
00:01:07,140 --> 00:01:12,060
RD-180 engine operating parameters also continue
to look good.

16
00:01:12,060 --> 00:01:18,420
Now passing one minute into flight.

17
00:01:18,420 --> 00:01:24,329
And Mach 1, Atlas V is now supersonic.

18
00:01:24,329 --> 00:01:29,010
And vehicle now throttling up, engine response
looks good; continue to see good chambers

19
00:01:29,010 --> 00:01:33,170
on both SRBs.

20
00:01:33,170 --> 00:01:36,750
One minutes, 20 seconds into flight.

21
00:01:36,750 --> 00:01:42,450
Body rate responses on the vehicle look good.

22
00:01:42,450 --> 00:01:44,850
One minute, 30 seconds in.

23
00:01:44,850 --> 00:01:47,860
Standing by for SRB burnout.

24
00:01:47,860 --> 00:01:50,360
And we have burnout on both solid rocket boosters.

25
00:01:50,360 --> 00:01:53,620
Atlas will hold on to the SRBs for an additional
48 seconds prior to jettison.

26
00:01:53,620 --> 00:01:57,890
RD-180 has gone back up to full thrust, as
expected.

27
00:01:57,890 --> 00:02:02,360
Engine response looks good.

28
00:02:02,360 --> 00:02:05,130
One minute, 50 seconds in.

29
00:02:05,130 --> 00:02:10,970
Atlas is now 17 miles in altitude, 11-and-a-half
miles downrange distance, traveling at 2,300

30
00:02:10,970 --> 00:02:11,970
miles per hour.

31
00:02:11,970 --> 00:02:14,850
Now passing two minutes into flight.
