NASA 1:	OK, ease off on your Hdot, Bill, it's level here.
Dana:	OK.
NASA 1:	You're 1.5 on velocity and about 43,000.
Dana:	OK, how far out?
NASA 1:	5 miles out, Bill. Now you can push her over again. You're in good shape.
Chase:	Chase 4, Tally Ho.
Dana:	I am in jettison, John.
NASA 1:	You're about 1.1, standby to watch your a. You'll be going subsonic shortly.
Dana:	OK, got flaps, squat, kicker, 3rd skid.
NASA 1:	OK, 2 miles out, 40,000 feet, you should be going subsonic. That's just beautiful. OK, Bill, you got her, and I understand you finished all your circuit breaker checks?
Dana:	Yep, and I got some buffet here at 9/10 and 9 a, its not serious but it's something the next guy should be aware of, I am sure.
NASA 1:	OK, Bill.
Chase:	..........
Dana:	Say again, Pete.
