McKay:	Roger. 45,000 inertial altitude and ..........
NASA 1:	What's your a and b?
McKay:	a is +3 and b is zero. Tank temp is a -20 #1 and #2. Ready to go, Jack?
B-52:	Yes, 2 minutes.
McKay:	2 minutes, data on.
Peterson:	Doppler velocity is 430 knots.
McKay:	Head bumper down. Prime switch to prime.
B-52:	What's your direction?
McKay:	I'm heading 222°, Jack.
B-52:	Roger, ours is 228°. 1 minute to launch System arm, arm light on.
McKay:	Roger. Ignition ready light. 20 seconds, Jack?
B-52:	Check. Precool?
McKay:	Roger, got a light. LOX pump bearing is a +12. Manifold. 10 seconds, pump idle, both coming up. Launch light. And I'11 see you later, Jack.
	Launched
McKay:	Got a light.
NASA 1:	OK. Track is looking good, we don't have much altitude yet, 20 seconds.
B-52:	Everything looks good, Jack, your heading is perfect.
NASA 1:	Little low on altitude. 40 seconds. Altitude is coming up parallel, looks like you're gaining on that now. On profile at 60 seconds, you're over-shooting on altitude a little. 1000 q here, up to 68,000. Steady on a 1000 q at 70,000. Coming flat at about 71, 72, 1100 q. Holding at 72,000 and you're drifting left on course. 1200 q, 1400 q.
McKay:	Shutdown.
NASA 1:	Speed brakes closed. Still holding level at 72.
McKay:	On the SAS.
NASA 1:	Going to pull-up any, Jack?
McKay:	Roger, I'll try and get my SAS reading.
NASA 1:	You're now at 800 q, showing you climbing. You're coming up through 76,000 and abeam of Cuddeback. Out with the speed brakes. You can pushover, too. Speed brakes out, Jack?
McKay:	They're going out, they appear to be stuck.
NASA 1:	OK, turn to your right, you have the lake in site?
McKay:	Rog.
NASA 1:	Just past Boron. Better come on around to the right. Jack, you can retract your speed brakes and continue on around in a right turn and pick up the pattern.
McKay:	OK, Joe, I read you now. I had trouble with my speed brakes up there, they stuck.
NASA 1:	Leave your brakes closed, Jack, and continue around in your turn.
McKay:	Roger.
NASA 1:	We have you at 1.6 Mach number.
McKay:	How does the turn look?
NASA 1:	40,000, 38,000. Looks like if you continue on around you'll get in pretty good shape. Mach 1 at 35,000.
Chase:	Altitude, Jack?
NASA 1:	We have him at 33.
McKay:	I'm indicating 30, going to pressurize. Going to jettison. Am I jettisoning?
Chase:	.......... I don't have you yet.
NASA 1:	He's coming up just west of the north lakebed, Danny, and coming through 25,000.
Chase:	Understand.
McKay:	Jettisoning now, Danny. Going to pressurize.
NASA 1:	Wait till you're below 20, Jack.
McKay:	OK, Joe. And pressurize.
NASA 1:	OK. What speed are you carrying, Jack?
McKay:	300 on the button, Joe, coming up on 310. Got me, Danny?
Chase:	Roger. Have you got ..........
McKay:	Affirm. OK, you call the ventral. Rough, Danny, isn't it? Let's have the ventral?
Chase:	Not yet. Let her drop. Ventral is ...... Flaps. Gear. Good gear. l0, 5, 2, good!
	Landed
McKay:	OK, everything appears to be normal.
NASA 1:	Jack, will you disconnect your physiological leads if you can out there, before you shut the data off.
McKay:	Sure will. Cycle my controls. Flaps coming up. Speed brakes going up. On auto. #1 hyd 3200, #2 is 3400. Peroxide tank pressure is 80. APU bearing temps +70 #1 and +75 on #2. Peroxide low light is off. Mixing chambers are -60 on #1 and -30 on #2. #1 source 1800 and #2 is 1550. APU sources #1 is 2600 and #2 is 2800. Cabin sources reading 2000. I 'm reading 164 on the ball. Inertial height at a -1800 (?) .......... 500 feet a minute. X-15 oxygen pressure is 1200. Speed brakes coming closed. Platform off. Pressurized. Circuit breakers coming off. APU's shutting down.
