Countdown Commentator: Ten, nine, eight, seven,
six, five, four, three, two, one, and liftoff. The rise of Starliner and a new era of human
spaceflight. Launch Commentator: Now ten seconds into flight. Vehicle’s begun the pitch-over program. Body rate responses look good. Now 15 seconds in. (Inaudible). Now 26 seconds into flight. RD-180 now throttling down to partial thrust,
as expected. Engine response looks good. Now 38 seconds in. RD-180 engine operating parameters continue
to look good. Vehicle is now passing through Max Q – maximum
dynamic pressure. Chamber pressures on both SRBs continue to
look good. RD-180 engine operating parameters also continue
to look good. Now passing one minute into flight. And Mach 1, Atlas V is now supersonic. And vehicle now throttling up, engine response
looks good; continue to see good chambers on both SRBs. One minutes, 20 seconds into flight. Body rate responses on the vehicle look good. One minute, 30 seconds in. Standing by for SRB burnout. And we have burnout on both solid rocket boosters. Atlas will hold on to the SRBs for an additional
48 seconds prior to jettison. RD-180 has gone back up to full thrust, as
expected. Engine response looks good. One minute, 50 seconds in. Atlas is now 17 miles in altitude, 11-and-a-half
miles downrange distance, traveling at 2,300 miles per hour. Now passing two minutes into flight. RD-180 engine operating parameters continue
to look good at full thrust
