Chase:	Rog.
Neil:	Down.
Chase:	Rog.
Neil:	Right.
Chase:	Rog.
Neil:	Left.
Chase:	Rog.
Neil:	OK, I didn't see anything of the left. #2 BCS is now going on and #2 BCS source now reads about 3425 and #1 is 3450.
NASA 1:	Roger. 003, add 2° starboard and delete 1 minute please.
B-52:	Roger, delete 1 minute, 2° starboard. This is the 12 minute point now, I'm on altitude and airspeed.
NASA 1:	Roger.
Neil:	APU cooling switch is normal. Blowers and LN2 going on. Pressure cooling on. Cabin source reads 3450. Helium shutoff valve is open. #l hydraulic is -65 and #2 is -40. 12 minutes now, data coming on.

B-52:	10 minutes to launch.
Neil:	Rog, precool off. FCS data on. Analyzer check, Butch.
Butchart:	It's been on for about 1/2 minutes. We're starting to go, let's go.
Chase:	Want to check your flaps, Neil?
Neil:	Going down.
Butchart:	I've already started my check, I won't bother with it. I got a malfunction on the roll then, Neil.
Neil:	OK.
Chase:	Flaps are OK.
Neil:	OK, that's good.
NASA 1:	Butch, check X-15 power off.
Butchart:	Yes.
Chase:	Flaps are up.
Neil:	OK, thank you. NASA 1, the trim synchronizer is running, cycling back and forth.
NASA 1:	Roger.
Butchart:	Your .......... display .......... your head is on item 3, you got that in spec. We've got an intermittent one on 8, corrected itself, going on.
Neil:	OK.
NASA 1:	Neil, give us #2 source reading.
Neil:	#2 engine source is 3100.
Butchart:	I have a failure on 15 that's not correcting itself.
NASA 1:	Roger.
Neil:	Going to shoot me down on that?
NASA 1:	Butch, we will proceed.
Butchart:	Roger.
B-52:	30 seconds from turn point.
NASA 1:	Rog, looking good, Jack.
Butchart:	We've got a temp failure on 30, going on.
Neil:	Was that intermittent, Butch?
Butchart:	No, it stayed at 31 again.
Neil:	0K.
B-52:	7 minutes, verify and turning.
NASA 1:	Roger, you can have 1 minute 40 seconds lead time on the drop point, Jack.
Butchart:	.......... I'm 32 here, also going on.
B-52:	Jack, you lost me on that 1 minute 40 sec. I didn't hear what you said.
NASA 1:	You can have an overlead of 1 minute 40 sec. on your drop point.
B-52:	Rog.
NASA 1:	003, can you tighten up your turn, just a tad?
B-52:	Rog, and we passed the 6 minute point 15 seconds ago. Neil, will you verify please?
Neil:	OK, Aux cabin pressure switch is on. Platform is internal. Fire ext on auto. Engine oscillograph and vibration recorders on.
Butchart:	OK, we're at end of test and the test light is on. #l3 is the only one in question then?
Neil:	Rog.
B-52:	5 minutes, verify please.

Butchart:	OK Neil, confirm check OK.
Neil:	OK, I'm indicating about 2° + stabilizer test. Got a reset ..........
NASA 1:	OK, Neil, everything says go down here, let's proceed.
Neil:	OK. And I want to confirm whether I should try the outer lids or not?
B-52:	4 minutes, confirm please.
Neil:	4 minutes, verify topoff.
Butchart:	Complete.
NASA 1:	Neil, on your last request, that's affirmative, go ahead.

NASA 1:	Roger.
Chase:	Jettison check OK.
B-52:	3 minutes, verify.
Neil:	Rog, 3 minutes, I'm now on X-15 radio ...........
NASA 1:	We read you clear but weak, Neil.
Neil:	.......... when you want to give me this radio check?
B-52:	NASA 1, give him a radio check.
NASA 1:	How do you read?
B-52:	Neil, how do you read?
Neil:	Don't read him at all.
B-52:	He's not reading you at all.
NASA 1:	We will proceed, 003, relay messages.
B-52:	Rog. I will relay the messages, Neil. We will proceed.
Neil:	OK. I' m on lower antenna. X-15 radio ............ Inertial velocity is ............. Push to test ball nose.
B-52:	2 minutes, verify.

Butchart:	Doppler velocity 690.
NASA 1:	003, are you relaying messages to 672? 672, NASA 1.
B-52:	Go ahead, Jack.
NASA 1:	Roger, are you reading 672?
B-52:	672, give me a quick count. OK. I read you with a squeal, this is the 1 minute point, everybody verify.
NASA 1:	Roger, we will proceed.
Neil:	..........
B-52:	35 seconds now, confirm, flight control system is OK.
NASA 1:	Roger, let's go.
B-52:	They say let's go. I have arm light on.
Neil:	20 seconds, pump idle. 350 pounds, 10 seconds. Igniter idle OK. I got oil pressure .......... fuel .......... 3-2-1, release.
B-52:	He's away, NASA 1.
NASA 1:	Roger, thank you, Jack.
Neil:	Cabin pressure 350 ..........

NASA 1:	Looks good down here, Neil. How do you read NASA l?
B-52:	Neil, you're looking good from NASA 1.
Neil:	OK .............
NASA 1:	35 seconds, Neil.
Neil:	Roger, and a rudder pulse.
B-52:	35 seconds.
Neil:	And advise flight control system strain gage just went out.
B-52:	Flight control system strain gage went out.
NASA 1:	Roger. 55 seconds, pushover.
B-52:	55 seconds, pushover.
Neil:	Pushover.
B-52:	Pushing over into the sun, NASA 1, everything looks good from here.
NASA 1:	Thank you, Jack.
Neil:	..........
B-52:	He's getting cycling in yaw and I think he went to fixed gain to pick it up.
NASA 1:	Roger. Going through 75,000.
Neil:	.......... on the altitude, coming level now.
B-52:	Altitude 75, coming level, NASA 1.
NASA 1:	Roger. Edwards area .......... 92, 93, shutdown.

NASA 1:	Going slightly down hill, Neil, pullup.
Neil:	.......... roll.
NASA 1:	3300 feet per sec.
Neil:	10° right roll.
NASA 1:	We have you about 78,000 at 3000.
Neil:	.......... I'm not reading anybody very well ...........
NASA 1:	Neil, turn 5° left.
Neil:	..........
NASA 1:	We have you at 2400 feet per sec. Turn 5° left.

Neil:	OK. I've got the lake in site now.
NASA 1:	Roger, understand you've got the lake in sight. 2000 feet per sec.
Neil:	Yaw fixed gain. Pitch pulse. Re-cycle to the 10 ....... Pitch pulse. Another pitch pulse. Can't see any damping, pretty dry up here.
NASA 1:	Roger, we have you 20 miles northwest.
Neil:	Re-engaging the damping. The pitch didn't re-engage the first time, pulse did not the second time. I've got fixed gain in pitch.
B-52:	We're completely unreadable as far as the X-15 goes.
NASA 1:	Roger.
Neil:	I'm getting you now, Jack.
NASA 1:	Roger, understand you're reading Neil, turn left, keep bringing it around to the left.
Neil:	..........

Neil:	Slowing down through .......... now.
B-52:	Over Mojave at 60,000, Neil.
Neil:	And re-affirm, I'm unable to get anything .......... Butch.
NASA 1:	Neil, you were unreadable, say again.
Neil:	I'm fixed gain at pitch. I'm down to 220 knots.
NASA 1:	Roger. Just have you going subsonic.
Neil:	Limit cycle again, .......... yaw and fixed gain .......... pitch damp at 220 knots.
NASA 1:	55,000.
.......... :	..........
Neil:	Pitch damp and a roll here at 240, correction, that's a yaw pulse and it doesn't look too bad. Looks like it would be OK to go .......... in this configuration.
NASA 1:	Roger, keep bringing it around to the left, you're heading for the south lakebed.
Neil:	Roger, Jack. I've got the runway in sight.
Chase:	Go ahead and jettison, Neil, if you read me.
Neil:	OK, going to jettison now at 45,000.
Chase:	Say your altitude again and ......
Neil:	I'm 43,000 now, about 7 miles west of base.
Chase:	OK, I have you in sight.
Neil:	OK, peroxide has stopped jettisoning. .... igniter ...... Tank pressures beginning to drop down ...... Going through 37 .......
Chase:	OK, Neil, I have you, you're little high.
Neil:	I'm going to put out a little brakes here.
Chase:	I have him in sight. I'm on your right wing, Neil.
NASA 1:	We have you at 30,000.
Neil:	Say again?
NASA 1:	30,000.
Neil:	Roger, I've got 27, ventral is armed.
Chase:	Neil, going through 25, coming up on 24 now.
Neil:	OK.
Chase:	Use speed brakes if you want to.
Neil:	OK, I'll use a little more, point it down a little more .......... and start bringing the brakes in. 16, going to pressurize.
Chase:	Doing about 300, 310 right now.
Neil:	OK, I've got about 295 on mine. Brakes are in.
Chase:	11,300 feet.
Neil:	OK, little more brakes. And, you're going to call my ventral, right?
Chase:	Rog, I'll call when you're clear.
Neil:	I'm not reading you too well, so make it nice and loud. Brakes coming in.
Chase:	Get ready to drop any time.
Neil:	It's off, flaps going down.
Chase:	OK, looks good. Gear down, looks good. Good show, Neil. About 10 feet, 5. Beauty, Neil.
Neil:	Thank you, Dad. FCS is disengaged. Flaps coming up.
NASA 1:	Engine master off, Neil.
Neil:	Engine master is off and stopped. Clear the controls on ...... Push to test ball nose. Test, data coming off. Hydraulic press is 33 on #2 and 34 on #1. Temp +40 on #1 and +40 on #2. Peroxide tank control is 580. APU bearing +6O and +75. No peroxide low light. Seat chambers are -50 and -45. Helium source Fox is last, #1 is 1800, #2 is 1800. APU source is 2300 on #1 and 2500 on #2. Cabin source is 2050. 3 axis ball heading 203. Inertial height is like, maybe -30,000. Inertial climb is 1300 feet per sec.
