NASA 1:	Got a good light, standby for ..... On profile, on heading, coming up very nicely. On profile. On heading. OK, standby for your pushover. Read us, Milt?
Thompson:	Affirm, Jack.
NASA 1:	Roger. Looking good, watch your angle of attack and g. Standby for throttle back. Very nice profile. Is your throttle back?
Thompson:	Affirm.
NASA 1:	OK, standby, angle of attack and speed brakes. Profile and good heading, Milt.
Thompson:	OK.
NASA 1:	Watch your angle of attack. Shutdown, 53 on shutdown. Push to zero a. Check your brakes.
