Butchart:	Az switch to inertial.
B-52:	7 minutes.
White:	Engine oscillograph and vibration recorders on.
B-52:	6 minutes.
White:	Aux cabin pressure is on. Fire extinguisher on auto. Engaging the MH-96.
NASA 1:	Tighten your turn a little bit, Fitz.
B-52:	Roger, tighten up a little bit.
NASA 1:	Bob, confirm oscillograph and vibration recorders on.
White:	They are on.
B-52:	5 minutes.
White:	I'm on X-15 oxygen and the pressure is 2600. Cabin altitude 35,000. Ventral is armed. Standby for the topoff call.
Butchart:	Topoff is complete.
White:	Roger, going to pressurize. Data and calibrate.
NASA 1:	Both BCS on, Bob?
White:	Both BCS are on. Pressures are up. LOX is up to 50 psi, locked out. Ammonia is at 47.
NASA 1:	OK, you're on X-15 oxygen?
White:	Roger, X-15 oxygen on, LOX and ammonia jettison switches to select. Jettison check now.
B-52:	4 minutes.
White:	Data off. Intercom switch off. We are on our radio.
NASA 1:	Read you loud and clear.
Butchart:	Platform in specs, looks real good.
White:	Inertial velocity is running around, little over 800 fps. Attitude looks good.
B-52:	I've got 430 knots up here. 2 minutes 45 seconds.
White:	APU bearing temps are +80 and +100.
NASA 1:	Bob, give us an oxygen quantity check.
White:	I put it on at about 2600 psi.
Chase:	NASA 1, Chase 4 got a fire warning light.
NASA 1:	Affirmative. Can you take Chase 4, Danny?
Chase:	I think 3 is going back to Chase 4, but I don't think I'm quite going to make it, Bob.
NASA 1:	OK..
B-52:	2 minutes.
White:	Both data on. Push to test. OK, after push to test the a settled down on +2.
NASA 1:	Roger, +2, what's the beta?
White:	Zero. Cine camera pulse. Head bumper coming down.
B-52:	1 minute.
White:	Prime switch to prime. Got an igniter ready light.
B-52:	40 seconds. Master arming on.
White:	Precool is on. Igniter idle switch is on. LOX pump bearing is +5.
	(Unable to hear launch countdown and launch)
White:	Reading 207° on heading. Everything looks good.
NASA 1:	Understand 207°. Track and profile looking good now, Bob. You're a little bit low on a.
White:	Roger. Little oscillation,.......... little bit, not much.
NASA 1:	Profile looks good, track is good. 40 seconds now. Profile is looking good right now, track is good. 75, 76, shutdown. A little low on profile.
White:	FCS on auto.
NASA 1:	Still a little low on profile. Track is good. Chase 3, you still have about 5 minutes to get here.
Chase:	Rog, I'm just passing Hidden Hills.
White:	37,000 in the cockpit.
NASA 1:	Understand 37,000 in the cockpit. We have you at 170 right now. Your track is looking real good. Profile still a little low.
White:	.......... at 183 ..........
NASA 1:	Roger 183. Profile is looking good, Bob, little bit low. Watch the stabilizer.
White:	.......... your 3 g's right now.
NASA 1:	3 g's, understand. We have you at 80,000 now.
White:	..........
NASA 1:	Don't go to speed brakes yet.
White:	Showing 4000 fps. Fixed gain.
NASA 1:	Danny, he's coming up on Cuddeback now.
White:	I got adapters, speed brakes coming out.
NASA 1:	You're about 15 miles out now. You can go to full brakes now.
White:	I got them.
NASA 1:	Chase 3, I don't think he will make it, he is about 5 miles from High Key.
Chase:	Neg. I'm still short of Three Sisters. Chase 3 will definitely not make it.
NASA 1:	Roger.
White:	.......... speed brakes coming in, they're in. Jettison. OK, coming up on downwind leg, North Lake, 180 shortly at 22,50O.
NASA 1:	Looks good here, Bob. Your jettison is just about complete now.
White:	Shows that way here too. Going back to pressurize. I checked the ventral is armed. Turning to base now. Turning on final now.
Chase:	Got you in sight, but I'm too far back to do you any good.
White:	OK. Ventral is coming off now.
NASA 1:	OK, Bob.
White:	I felt it go. Flaps are coming down.
NASA 1:	Looks good, Bob. 15 feet, 10, 5, Beautiful!
White:	System is disengaged. Data is off. Heading and temps are looking OK. Hyd temps are +50 and +45. Hyd pressures are 3350 on #l and 3250 on #2. H2O2 tank press ....... APU bearing temps are +60 and +85. No peroxide low lights. Mixing chambers are -45 and -55. (?) Engine helium source ........ Helium source ....... APU source #1 is 2150 and #2 is 2650. Cabin source 1850. 3 axis ball heading 197°. Inertial height 87,000. Inertial climb 400 fps. X-15 oxygen pressure 2000.
