McKay:	OK, flap circuit breakers. Data off.
NASA 1:	Give us another set of APU tank readings, Jack, and we're looking around for 550, is it 600 and not 500?
McKay:	You're right, they're 550.
NASA 1:	OK, Jack.

NASA 1:	Roger, understand, Jack. 4 minutes now.
McKay:	4 minutes.
NASA 1:	Your hydraulic pressures steady?
McKay:	Roger, about 3300. Going to pressurize.
NASA 1:	Were you in buffet then, Ken?
B-52:	Little left roll in that last turn.
McKay:	Pressure coming up. Ammonia reading 45, LOX is 48. Jettison switches jettison. You say you were in buffet, Ken?

NASA 1:	Roger. 15 seconds to l minute. Standby for l minute, now.
B-52:	1 minute.
McKay:	1 minute. Prime. Igniter ready light. Precool. Igniter idle. OK, going pump idle now. Pressures coming up. .......... 3, 2, 1, launch.
Chase:	Good light, Jack.
NASA 1:	OK, Jack, your track was real good when you launched.
McKay:	Rog. There goes the platform.
NASA 1:	Understand platform is gone.
McKay:	Roger, I'll be pushing over at 40 seconds.
NASA 1:	Rog. Track is real good, pull it on up. Should be on theta.
McKay:	The whole inertial is gone.
NASA 1:	OK, Jack, go to your "G" reading. Pull it up just a little bit.
McKay:	..,......... inertial. ..........
NASA 1:	Rog, that was 49 seconds.
McKay:	........ what's my altitude?
NASA 1:	You're 60,000 now, looking good. Keep coming up a little bit.
McKay:	Velocity?
NASA 1:	Rog you're 3° a, Jack.
McKay:	Give me velocity?
NASA 1:	Standby.
McKay:	And altitude?
NASA 1:	You're 80,000 now, Jack, and should be coming up about 4500.
McKay:	RAS shutdown.
NASA 1:	Roger. OK, let it climb on up. Speed brakes in now. That's 90,000.
McKay:	How's my heading?
NASA 1:	Your track is real good, Jack. Fly at 200 q, 200 q. Have you 46 now. Hold it up. Hold 200 q, Jack, if you can.
McKay:	250.
NASA 1:	Roger, 200 q and you're down about 3700 fps, 100,000. Hold the nose up if you can, Jack.
McKay:	250.
NASA 1:	Lets get it down to 200. 36 on velocity and approximately 90,000 feet.
McKay:	How's my energy?
NASA 1:	Your energy is good, you're inside Edwards, its close, so hold the nose up. 200# q, Jack, try to hold that 85,000. Mach 3 now.
McKay:	Position?
NASA 1:	What q are you reading now?
McKay:	What's my position, Bob?
NASA 1:	Your heading is good and you're about opposite Ballarat, 65 north. 27 on velocity, right on the track, Jack. How are you doing on q, Jack?
McKay:	About 250, I can't get her down.
NASA 1:	OK.
McKay:	Run out of time -
NASA 1:	We have you 80,000 feet, right on track, heading for Edwards. Have you 24 and approaching Pilot Knob.
McKay:	Rog. Altitude?
NASA 1:	You're just under 80,000. Have you 22 and hold your altitude. Your q meter may be going bad now.
McKay:	250 on q.
NASA 1:	Roger, have you about Mach 2.
McKay:	Rog.
NASA 1:	250 would be a good q number right now and you're about 6 miles from Cuddeback.
McKay:	Am I to the right or left of Cuddeback?
NASA 1:	You're going right over the center of Cuddeback. You're coming down close to 70,000. 17 on velocity and you can go to jettison and start down a little bit.
McKay:	Jettison.
NASA 1:	Roger. You're over Cuddeback and start the nose down a little bit. Your pressure indicator instrument should begin to read now.
McKay:	Rog.
NASA 1:	We have you about 13 and 25 north, coming through 65,000.
McKay:	Rog. I don't have the field yet. Mach number?
NASA 1:	Have you about 1.2 right now, Jack, 60,000 feet, and you can turn left a little bit and look at the base.
McKay:	Got it.
NASA 1:	Watch your angle of attack and you're only about 10 miles north.
McKay:	Speed brakes.
NASA 1:	Rog. You're on your own.
McKay:	Pull speed brakes in, Bob.
NASA 1:	OK, Jack. Have you about 50,000 here.
McKay:	Rog, 45. Mach number?
NASA 1:	You're Just under 1.
McKay:	OK, turning in. Give you a readout here, all my inertial instruments; attitude, altitude, velocity and H dot went out at drop.
NASA 1:	Rog.
Chase:	Can you go to jettison? I have you already.
McKay:	Going to jettison, Joe. OK, speed brakes. Mach 2 again, Joe. Got a little buffet at 280. Pretty bad.
NASA 1:	Roger.
Chase 4:	Tally ho!
McKay:	Coming down through 32, what do you have, Bob?
Chase:	Have 31.
NASA 1:	We were showing 35, but its a little off, Jack.
McKay:	Rog. Speed brakes coming out. How does jettison look, Joe?
Chase:	Coming through 25 now, Jack.
McKay:	We'll juggle around here a little bit.
NASA 1:	You can go to pressurize, Jack.
McKay:	Speed brakes.
Chase:	21,000.
NASA 1:	Engine master off.
McKay:	Say again?
NASA 1:	Master off, check circuit breakers, squat switch.
McKay:	Did you hear that, Joe?
Chase:	Check your squat breakers.
NASA 1:	Squat switch and circuit breakers.
McKay:	Got them.
Chase:	Coming through 12,500.
McKay:	Rog. Brakes in.
Chase:	7,000.
McKay:	Say again.
Chase:	6500 now.
McKay:	Brakes coming in.
Chase:	Flaps coming down. No gear yet, there they come, 3 good ones. 5, down, good.
NASA 1:	Engine master off, Jack?
McKay:	It's off. Sure got left roll on landing there. Ball is spinning. X-15 oxygen pressure 1500 Hydraulic pressures 3450 on #l and #2. H202 tank 550 on #l and #2. APU bearing temps +80 on #l and +50 on #2. No low lights. Mixing chambers -40 on #1 and -50 on #2.
McKay:	Engine helium source #1 and #2 is 1800. Fox zero. APU source 2200 on #1 and #2. Cabin source.
