NOTE:	(Page #3 of transcript is missing)
NASA 1:	Roger. 48 now, Bob.
Rushworth:	Roger, 475 now.
NASA 1:	Roger. Your track looks real good. 46 and about 500 q.
Rushworth:	Roger. Little below profile, Pete?
NASA 1:	Little below, roger. 44 on velocity.
Rushworth:	Roger. Get that little zing in pitch again!
NASA 1:	Roger.
Rushworth:	Right through here.
NASA 1:	42 now. About 700 on q and to the left of track. Mach 4.
Rushworth:	Roger at 48,000. ..........
NASA 1:	Roger. And the track looks good, Bob. About 600 q.
Rushworth:	It's the strangest little feeling!
NASA 1:	Roger. 35 now.
Rushworth:	50, 50 miles, that right?
NASA 1:	No, we'll call 50 miles, Bob.
Rushworth:	475 on q.
NASA 1:	Roger.
Rushworth:	76,000 and 3.1.
NASA 1:	Roger. And you're 50 miles at 2.8.
Rushworth:	Roger. Doing a sideslip. On computer data now.
NASA 1:	Roger. And you seem to be drifting a little more to the right of track now.
Rushworth:	.......... coming down, speed brakes out.
NASA 1:	Correction, to the left of track. 25.
Rushworth:	Roger. I'm a little behind in my profile.
NASA 1:	Roger.
Chase:	..........
Rushworth:	I'm a little behind on my profile.
Chase:	Roger.
NASA 1:	And you want to hold the altitude a little bit and we'll call you at Cuddeback.
Rushworth:	Roger. I got 60,000.
NASA 1:	Roger.
Rushworth:	Speed brakes in.
NASA 1:	Rog, they're in and you're Cuddeback now.
Rushworth:	Roger.
Chase:	I'm coming, just high key now.
Rushworth:	Roger.
NASA 1:	And you better turn just a little bit to the right, Bob, about 5°, you're to the left of track.
Rushworth:	500# q, 57,000, Mach 2 when I did that pulse. Dampers back on.
NASA 1:	Roger. 1.8, Bob and a little bit more to the right.
Rushworth:	OK, got it, Pete.
NASA 1:	And ASAS back on.

NASA 1:	Roger. And your squat switches and circuit breakers, Bob.
Chase:	..........
Rushworth:	Roger, my flap circuit breakers are in.
NASA 1:	Roger.
Rushworth:	Squat circuit breakers are engaged. Got 7-1/2° angle of attack, and 1-1/2 g's, and I'm getting that buffet again.
NASA 1:	Rog.
Rushworth:	OK, I'm down to, little slower in speed. 300 knots, I got a 320 on 4. I got 10° angle of attack, almost 2 g's .......
NASA 1:	Roger. Got you at 30,000.
Chase:	24,500.
Rushworth:	Say again?
Chase:	We're about 22,000 right now.
Rushworth:	I'm showing 21 right now.
Chase:	Roger .......
Rushworth:	Roger, 300 knots.
Chase:	I'm showing about 310.
NASA 1:	14,000 and 300.
Rushworth:	Roger. Have to use a little speed brakes I guess.
Chase:	OK. Showing 310. Coming through 10,000 now.
Rushworth:	Roger. Better get some speed brakes, finally got them!
Chase:	Roger. 7,000 now. Showing 330. 310 now, Bob.
Rushworth:	Roger. Flaps.
Chase:	Flaps are coming.
Rushworth:	Gear.
Chase:	Roger, 270. Two good ones, nose is down. 3 good ones. 10 feet, 5, 3, 2, beauty!
Rushworth:	Clock is reading 82 seconds. I overshot to 5200 fps. Inertial height is just above zero. H dot is -10. Inertial velocity came to zero when we did. Fox source is zero, tanks are zero. Pump inlet zero. #2 is zero. Peroxide is 560. APU sources, #1 is 25, #2 is 26. Hydraulics are 30. Cabin source is 1450. #1 and #2 APU bearings, -45 and -50. Mixing chambers, #1 APU is floating around, looks a +50, #2 is +60. X-15 oxygen is 2000.
