12 Minutes to launch
 

Walker:	Data. #2 APU.
Chase:	#2 jettisoning.
Walker:	#1.
Chase:	#1 is jettisoning.
Walker:	#1 crapped out!
Chase:	Jettison quit too.
Walker:	I misread my pressure gage, it was moving high above 4000, running OK.
NASA 1:	Wait until you get 40 seconds before you recycle it, Joe.
B-52:	11 minutes.
NASA 1:	OK, Joe, you can start the other one any time now.
Walker:	There was no problem with the APU, I misread the gage and cut it off myself. Controls and flaps.
Chase:	OK, Joe, all going up and down.
NASA 1:	Precool off, Joe, and do you have both alternators on the line?
Walker:	Precool is off.
Chase:	Flaps are still down.
Walker:	Engine reset. Hydraulic and electrical power check OK. Flap check OK, going back up. Breakers are in. Data off. MH data on. Platform internal.
NASA 1:	OK, and check your reset generators. We're not showing both of them on the line here.
Walker:	Both are on.
B-52:	10 minutes.
Walker:	Go ahead, Butch.
Butchart:	I'm already restarted, Joe.
Walker:	I'm at 348 heading, 800 fps, 44, 500 vertical velocity. Good attitude. a 2°, and b about 1/2° left.
NASA 1:	Roger, Joe.
B-52:	I have 347 on your heading, Joe.
Walker:	Face plate heat is now on low.
B-52:	Just past 9 minutes, 8 minutes still look good for turn?
NASA 1:	Roger, 8 minutes. Your course is looking very good.
B-52:	Looks like we might possibly be just placed a little west of the track but not too much.
NASA 1:	Fitz, what is your altitude?
B-52:	35,000, 8 minutes, starting turn now.
Butchart:	We're through all the pitch and all the roll OK, Joe.
Walker:	OK.
B-52:	7 minutes.
Walker:	Rog. Got it, Butch?
Butchart:	Roger, it's all green.
Walker:	MH data off. Reset the stabilizers.
NASA 1:	Chase 1, we're not reading you, can you verify squawking?
Chase 1:	Roger, I'm squawking.
B-52:	6 minutes, about 7 seconds ago.
Walker:	Aux cabin switch is on. Blood pressure is on. Fire extinguisher auto. Engage MH-96. MH BCS in auto. We're working standard on controls and flaps, zero on control and zero on indicator. Both BCS's on.
B-52:	5 minutes.
Walker:	At 3000, going to X-15 oxygen. Cabin altitude at 35,000.
B-52:	Your track is going to work out good, NASA 1.
NASA 1:	Roger, we will call your 4 minute point in just a few seconds. Let's call that 4 minutes now.
B-52:	OK, going to heading 170.
NASA 1:	That's a good heading.
Walker:	Topoff complete, Butch?
Butchart:	All set.
Walker:	Data, calibrate. Pressurize. Lox tank 50, fuel at 45. Data off. Peroxide tank about 610.
NASA 1:	Roger, Joe, everything looking good down here.
Walker:	I'm on X-15 radio, when you made that transmission, I read you good.
B-52:	3 minutes.
Walker:	Surfaces are zero. 44,000, vertical velocity about 500 fps. Bearing temps are +60 and +100. Roll hold on. Delta psi standby.
B-52:	2 minutes now.
NASA 1:	Looks good.
Walker:	Data on. MH data on. Tape to 15. Test ball nose. Checks OK. Cine camera to pulse. Head bumper down.
NASA 1:	Have our a, b crosspointers, Joe?
Walker:	OK, I'm 1° on a and 1° left on b.
NASA 1:	Roger. Delta psi on, Joe?
Walker:	Haven't got the 1 minute warning yet.
B-52:	1 minute.
Walker:	Delta psi. Push to CSS.
Chase:	Peroxide showing.
Walker:	Prime. Igniter ready light. Precool. Igniter idle.
NASA 1:	Position is looking good.
Walker:	Pump idle. Good pump, good igniter, ready to launch - now!
Chase:	Good light.
Walker:	OK.
NASA 1:	Have you on course and you're slowly coming up on profile. Have you coming little low on profile, on heading.
Walker:	OK, I was slow even at 2 g's.
NASA 1:	Roger. Coming up on 40 seconds. Heading looks good, coming up 80,000. Just a little low on theta. Profile looking very good, Joe, on heading. OK, 70 seconds, 83, 84 seconds.
Walker:	Right on target.
NASA 1:	Roger, and delta psi. Your heading and profile looking good.
Walker:	Start turning some ..........
NASA 1:	Roger. We're receiving you very good.
Walker:	By gosh, it's dark up here today.
NASA 1:	Roger, we might be going just a little high, on heading. OK, going just slightly over profile, Joe. Little high on profile. We have you going just a little right of course. Little high on profile.
Walker:	OK.
NASA 1:	We're not getting good angle of attack readouts down here.
Walker:	Quite a different view, what a beautiful day this is!
NASA 1:	Roger, buddy. Going very high on profile.
Walker:	OK, I've got Rogers dead ahead.
NASA 1:	OK, you have it in sight. We're leveling at 350. Coming abreast of Mud Lake now. Speed brakes 20°.
Walker:	Right, got them.
NASA 1:	You're going to be real good on energy. We're only showing 15° of brakes here.
Walker:	I've got 20° here.
NASA 1:	We're recommending the high side of 20°. We're recommending 25° a.
Walker:	OK, what kind of altitude are you reading?
NASA 1:	Coming up on 285. 280 now.
Walker:	OK, ball nose started to work again.
NASA 1:	Come up on a now, you're approaching 240.
Walker:	.......... -10° theta. ..........
NASA 1:	Roll hold off and delta psi standby. We have you about 8 miles right of course.
Walker:	That's nothing at this point.
NASA 1:	Just past Panamint, coming up on Owens Dry Lake.
Walker:	OK, getting q and g.
NASA 1:	Roger. Be about 400. Pull it up. 1000 q, Joe, 4 1/2 g's. And, we have you rounding out nicely. Recommend speed brakes in now, 4 g's.
Walker:	Right.
NASA 1:	We got the q peaked. You're fat on energy at China Lake. And, watch your bounce, don't bounce it too high. You can start easing over a little.
Walker:	OK, I now have a peroxide low light, BCS is off.
NASA 1:	Roger. We have you at Mach 3.
Walker:	And, going to transfer. Speed brakes out.
NASA 1:	Speed brakes out, I understand, you might have the field in sight, 150 is a good heading.
Walker:	Roger. I have 2.6, how do you read?
NASA 1:	2.5, Joe.
Walker:	I'm coming in.
NASA 1:	We're real fat on energy.
Walker:	How's pressure altitude?
NASA 1:	60,000.
Walker:	Closing the brakes for a little while.
NASA 1:	Roger. You're passing Saltdale now.
Walker:	I've got the field in sight all right.
NASA 1:	Coming up on 50,000.
Walker:	40 in the cockpit here. 100,000 by inertial.
Chase 4:	Tally ho!
Walker:	OK.
NASA 1:	Your present heading is looking good.
Walker:	Yes sir.
NASA 1:	Have you coming up on 40,000.
Walker:	33 here.
NASA 1:	OK, go to jettison any time.
Walker:	Going to jettison now and I have checked the flap breakers and landing disengage breaker.
NASA 1:	Roger. We have you about 12 miles northwest.
Walker:	Subsonic.
NASA 1:	On landing, we suggest you favor the middle or the east end of the new runway down there, little rough with holes on the west side.
Chase:	Going down through 26 now, Joe.
Walker:	That's what I have.
Chase:	330 knots.
Walker:	Roger, about 330.
NASA 1:	Give us a 20,000 foot count, Joe.
Walker:	Coming up on 20,000 - now!
NASA 1:	Roger. OK, we know you've done it, but recheck your squat and flap circuit breaker.
Walker:	Roger, done it.
NASA 1:	And, go to pressurize.
Walker:	Pressurize.
NASA 1:	You're in fine shape.
Walker:	Flaps.
Chase:	Flaps are coming down.
Walker:	Gear.
Chase:	3 good ones. 2 feet high.
Walker:	Can't get her on the ground.
Chase:	Real nice.
Butchart:	How you doing, Joe?
Walker:	Well, so we're done with the second cross country.
NASA 1:	Roger, we burned this plot up here, we didn't want you to see it.
Walker:	I see! Hydraulic pressures, #1 is 3400, #2 is 3300. Tank pressures, 560 on peroxide. Mixing chamber temps are (End of Tape)
