Chase:	OK, coming down.
Knight:	Coming Up.
Chase:	Coming Up.
Knight:	And the flap circuit breakers are in, Bill.
NASA 1:	Roger, Pete, and would you tell the B-52 to shallow his turn a little.
Knight:	Rog. Inertial gages look good, Bill. Attitudes look good and say again.
NASA 1:	Rog on the inertials. Chase 2, tell the B-52 to shallow his turn a little.
Chase:	Shallow your turn a little.
B-52:	Shallow or tighten it?

NASA 1:	Then we want them reset and verify hi low hi.
Knight:	Hi low hi?
NASA 1:	Roger, Pete.
Knight:	What's the problem?
NASA 1:	It's OK, Pete. We thought we might have some SAS trouble but it's good. We want door to experiment pressure, Pete.
B-52:	4 minutes, Pete.
Knight:	Rog, the experiment door is 1300 and 2100.
NASA 1:	Rog, got the pressures and we're past four minutes.

NASA 1:	OK, Pete. a over to zero. RAS on.
Knight:	Read me, Bill?
NASA 1:	Rog, Pete, loud and clear. a to zero. RAS on.
Knight:	Rog.
NASA 1:	We got your shutdown at 5.0, Pete, so you'll be going a little bit low.
Knight:	Rog.
NASA 1:	Engine master off, Pete.
Knight:	..........
NASA 1:	Say again, Pete. I am not reading you too clear.
Knight:	Do you want the experiment up?
NASA 1:	Negative. And can you advise us of your difficulty, Pete?
Knight:	I got 220.
NASA 1:	Roger. Why did you pushover early? We have you over the top at 220. Check you attitudes. 20 a will be good if that's what you want, Pete. Just as an advisory, you're about 10 miles left of track. So there will be a right turn after re-entry.
Knight:	Rog.
NASA 1:	We have you back through 200, Pete. Check your a. And that call was a little late. Have you coming through 180 now. We'll be entering about 25 miles up range from where you planned on, Pete, and you'll have to make a right turn, but you're going to have energy for ever.
Knight:	Rog.
NASA 1:	Back through 130, Pete. Check your G. And RAS off. Pete, have you back through 80,000. Standby for Hdot. And turn right, heading 215. OK, Hdot looks good, Pete. We have you 700 feet per second, 15 north of Cuddeback. Come further right, heading 220.
Knight:	Rog, 220.
NASA 1:	And your altitude is 70,000. You're level at 70 and that's good place to be. We have you 10 north of Cuddeback, Pete. Your Mach number is 3.2. Your energy looks very good, Pete. Further right, heading 225.
Knight:	Roger, 225. Coming on with the brakes.
NASA 1:	OK, Pete, we have you about 3 north of Cuddeback. And our radar shows you at 68,000.
Knight:	Right over Cuddeback.
NASA 1:	Have you at 2.8, Pete, at 67, 000, abeam of Cuddeback. You're at Mach 2.5, Pete.
Knight:	Rog, I got it.
NASA 1:	OK, Pete, we have you 15 miles north. Show you coming through 60,000 and let's bring your brakes in, Pete. You're at Mach 2.
Knight:	Coming in.
NASA 1:	You're 14 miles out. You have Edwards in sight?
Knight:	OK. Yeah.
NASA 1:	OK, Pete, we have you now aiming about 10 west of Edwards, you might want to come left, oh, 5, 10°. Have you at 10 miles out, Pete. You're at 54,000, your Mach number is 1.8. Get your window shade, engine master. And Chase 4, call the jettison when you want it.
Chase:	OK, go to jettison.
Knight:	Rog, jettison.
NASA 1:	OK, Pete, you're 50,000, your Mach number is 1.4. You're about 5 north of the highway. You're going to end up about 5 west of the North Base.
Knight:	I got it.
NASA 1:	Mach number is 1.3. Your altitude is 48,000 on the radar, Pete. When you have time get your PMR master off. Coming subsonic, Pete. Check your a. When you have time catch flaps, squat, kicker and 3rd skid.
Knight:	Rog, flaps are in.
NASA 1:	Rog, Pete.
Knight:	Rog, I am at 38,000.
NASA 1:	We're showing 40 here, Pete. 38 probably even better.
Knight:	OK, are you close to me?
Chase:	..........
Knight:	OK, lets get in and look the airplane over.
Chase:	Roger.
NASA 1:	Pete, do you have time to tell us what your difficulty's were?
Knight:	Yeah, in a minute, Bill.
NASA 1:	OK, pattern looks good, Pete. We show you through about 28 or 27,000.
Chase:	Stick kicker and 3rd skid. ..........
Knight:	I got all that. You close enough to look at the airplane?
Chase:	I'm just right behind you.
Knight:	OK, let's look it over pretty good.
Chase:	It's OK, Pete.
Knight:	OK, flaps.
Chase:	Down and locked. 10 feet, 5 feet, 3, 2, 1. You're down.
NASA 1:	Very nice, Pete.
