Thompson:	OK. Going to jettison.
NASA 1:	Chase 4, you ready for jettison?
Chase 4:	Rog, jettison and I got you, Milt.
Thompson:	OK.
NASA 1:	Coming subsonic right now, Milt, through 40,000. About 30,000 now, check your squat and flap circuit breakers.

NASA 1:	We got you here on radar, about 22.
Chase:	20,000 now. 16 now, Milt.
Thompson:	Rog.
Chase:	OK starting - Still got a little speed brakes out, there they go.
Thompson:	Yes. Flap.
Chase:	Flaps out.
Thompson:	Gear.
Chase:	Main gear is down. Nose gear is down. 5 feet, coming down, 2, 1, there it is!
NASA 1:	Very nice, Milt.
