NASA 1:	Everything looks good here, Jack.
McKay:	Slight oscillation. Ready to launch light. 400 on the manifolds. 5, 4, 3, 2, 1. launch!
NASA 1:	Good light, Jack. Watch your a. Check full throttle. Heading looks good. a looks good. Standby for theta.
McKay:	How's my heading, Bill?
NASA 1:	Very good, Jack. Track and profile very good. On heading, on track. Coming up on 80,000 feet. Now.
McKay:	Good shape.
NASA 1:	Good track, good profile. Coming up on 110,000 feet. Now.
McKay:	Pushing over.
NASA 1:	Understand, you're pushing over Shutdown. Track looks very good, Jack. Track and profile look very good. Have you coming up on 200,000 feet now, experiment on, Jack. Check b zero. Heading vernier to delta psi. Track and profile look very good, Jack.
McKay:	Did any computer lights come on? And reset? Its' reset now.
NASA 1:	Roger.
Chase:	Once he gets started in the zoom maneuver why he hasn't any control over until he gets back to air except for peroxide jets in the nose and on the wing tips.
NASA 1:	Track and profile look very good, Jack.
McKay:	What's the altitude, Bill?
NASA 1:	Coming over the top at 248, Jack. Your track and profile look very good. Let's start working your a up a little bit. Very nice. We have you coming through 180,000 now, experiment off. Delta psi to standby. Let's keep the a up, Jack. 150,000, check experiment off, Jack.
McKay:	Off.
NASA 1:	Keep the a up. And we have you slightly left of course, after reentry we will want a tight turn, Jack. Profile looks very good, 100,000 feet now. Coming through 80,000, standby for your H dot, Jack. Speed brakes to 35°. OK, you're H dot is looking good, start your right turn to a heading of, well, keep it coming to the right, Jack. Watch your H dot, don't let it go positive.
McKay:	Altitude?
NASA 1:	We have you at 70,000. Correction, Jack, that's 55,000. Keep her coming to the right. We have you 10 miles out and do you have Edwards in site?
McKay:	Rog.
NASA 1:	OK, keep her coming down, Jack. We have you little over Mach 2 and about 57,000. When you have time, Jack, check engine master off. Keep her coming right. Both speed brakes in, Jack. Have you coming subsonic, let's watch the a. Want to try a right-hand pattern?
McKay:	Rog.
NASA 1:	Chase 4, he's about over Main Base now, turning north for a right hand pattern to 18.
Chase 4:	Roger.

Chase:	I just missed him but I will catch him.
McKay:	Going to jettison.
NASA 1:	Rog, Jack.
Chase:	Tally ho!
NASA 1:	Have you coming through 40,000, Jack, how do your barometrics look?
McKay:	35.
NASA 1:	Very good. Jack, will you check your flap and squat circuit breaker and arm your stick kicker.
McKay:	Got them.
NASA 1:	We have you through 30,000 on our radar. How are your barometrics working?
McKay:	28.
NASA 1:	Very good. We have some speed brakes out, Jack.
McKay:	Will leave them out.
Chase:	About 22,000, Jack.
McKay:	Rog.
NASA 1:	Coming through 20,000 on the radar, Jack.
McKay:	Rog. 15.
NASA 1:	Rog, Jack. Just to remind you, you still have brakes.
McKay:	Rog. That's a good reminder, Bill, keep it up.
NASA 1:	Rog. Mr. Vensel is putting on his rose-colored glasses, Jack. And we have the brakes in.
McKay:	Out again!
Chase:	5,000, Jack. 310 knots.
McKay:	Flaps.
Chase:	And down. Mains and nose are down. 5, 4, 3, 2, 1. down, push, pull.
NASA 1:	And Jack, we'd like you to ease off on your back stick at 100 knots please.
McKay:	Rog. That's quite a rollout!
NASA 1:	That was a dandy flight, Jack.
McKay:	When I stated "pushover," had a computer malfunction and I reset.
NASA 1:	OK Jack, your profile was a dandy.
McKay:	Thank you. 167 on heading. Inertial height is 930,000. H dot is 100 fps. Oxygen pressure is 1300. Hydraulics are 3500 on both. Velocity is little over 200 fps. Bearing temps, #1 is 100, #2 is +80. No peroxide low light. Mixing chambers, -30 on #1 and -45 on #2. Helium sources are zero and fox is zero. APU source is 2000 on #1 and #2. Cabin source is 1500.
