13 minutes to launch
 

B-52:	13 minutes to launch.
NASA 1:	Roger. Looks like you're going up the old track for good, Fitz.
B-52:	The old climb reads not so good though, we're 43,700 now, might be 500-600 feet below at launch time, going to be pretty close.
NASA 1:	Roger.
Rushworth:	Little warm up here today.
B-52:	She likes to climb better with the out-rigger down.
NASA 1:	Bob, your latest report on your Mud Lake winds now are southeast at 15-20.
Rushworth:	Southeast at 15-20, Roger.
Russel:	Normal topoff cycle is complete, going to manual feed here to see if I can get a level flow.
NASA 1:	Roger, sounds good, Jack. Do not topoff the external tank.
Russel:	Roger. Looks like a long flume coming out of it every 10-15 seconds.
NASA 1:	Roger.
Russel:	Don't know if there's any liquid in it, but its a good round vapor.
NASA 1:	Sounds like its topping its own self up there.
Russel:	Sounds like it.
B-52:	11 minutes to launch about 10 seconds ago.
Rushworth:	Precools are off.
NASA 1:	Fitz, come 2° right.
B-52:	2° right to 002. 10 minutes to launch, heading 002, Bob.
Rushworth:	Roger. APU cooling switch going normal.
Russel:	LN2 switch off.
Rushworth:	Both blowers BLN2. Pressure cooling is on. My inertial gages are 41,000 and 900 ft/sec, zero rate of climb. Attitudes look good.
Russel:	Reading 836 in the B-52.
Rushworth:	OK.
B-52:	You're right about the rate of climb, Bob.
Rushworth:	Cabin source is 32.
B-52:	9 minutes, how does the time look, NASA?
Rushworth:	#2 APU is on.
Russel:	Rog, got exhaust.
Rushworth:	Ready for #l, Jack.
NASA 1:	OK, Bob.
B-52:	NASA 1, time still look good?
NASA 1:	Roger, we'll call 8 minutes. When you get a chance, Bob, give us auxiliary source pressure.
Rushworth:	Auxiliary source pressure 2250. Generators are reset and the engine is reset. 3500 on #1, 3400 on #2. Flaps going down. ......
Chase:	Flaps are going down.
Rushworth:	Flaps going up.
NASA 1:	Let's call 8 minutes now.

NASA 1:	Russell, set in 220 North.
Russel:	220?
NASA 1:	Affirmative.
Russel:	Is that what you got, Fitz?
B-52:	Affirmative.
NASA 1:	Mark it, Jack.
B-52:	Mark it, he says.
Russel:	Roger.
B-52:	Did you get the mark, Jack?
Russel:	Negative, they're tracking a long ways off.
Rushworth:	Aux cabin pressure switch is on.
NASA 1:	Jack, set in 30 West.
Russel:	30 West, Roger.
NASA 1:	Mark it, Jack.
Russel:	Mark.
B-52:	Just passed 6 minutes there, Bob.
Rushworth:	Understand 6 minutes. I've completed my SAS check, its all right. I'm not going to internal on the platform. Jack Russell, are you satisfied with that?
Russel:	Roger.
Rushworth:	OK, I'm internal in the platform. Fire extinguisher auto. The SAS check is complete, all gains are ........ is on and ASAS is on.
B-52:	NASA, you'll call 5 minutes, is that correct?
NASA 1:	Affirmative.
Russel:	NASA 1, good solid overflow on internal at 180 gallons remaining cruise.
NASA 1:	Thank you.
Russel:	Good trim on drop tanks.
NASA 1:	5 minutes now.
B-52:	5 minutes.
Rushworth:	O2 is 26. I'm on X-15. Cabin altitude is 36,500. Topoff is complete.
Russel:	Roger.
B-52:	Want us to roll out on launch heading, NASA l?

B-52:	Roger, roll out 183.
NASA 1:	4-l/2 minutes now.
Russel:	Topoff is all complete.
Rushworth:	Roger. Topoff is complete.
B-52:	Roll out 183.
NASA 1:	4 minutes now.
B-52:	Roger.
Rushworth:	Data on and calibrate. Tank handle to pressure.
Russel:	Roger, your vents look good out here.
Rushworth:	3 jettison switches to jettison. I saw .......... on fuel and 47. Ready for jettison check?
Chase:	Roger.
Rushworth:	Jettison off.
Chase:	It's stopped.
Rushworth:	Data is off.
NASA 1:	OK here, Bob. Come 2° right, Fitz.
B-52:	2° right. Looks good, Bob.
Rushworth:	And I'm on X-15 radio.
NASA 1:	5 square here.
Rushworth:	Roger.
B-52:	Just passed 3 minutes, Bob.
Rushworth:	Roger. I have 44,800 fps, heading looks good.
Russel:	B-52 has 676 fps.
Rushworth:	APU bearing temps, #1 is 110, #2 is 95. External tank ejection on. External tank data is on.
NASA 1:	Roger.

Rushworth:	Roger. Where's the 104?
Chase:	Right behind you at 38.
Rushworth:	Roger. ..........
Chase:	Speed, Bob?
Rushworth:	Pretty good.
NASA 1:	Keep turning, Bob, you're losing a little altitude.
Rushworth:	Am I over the lakebed?
Chase:	Roger, at 35.
Rushworth:	I think I better land to the east.
Chase:	OK.
NASA 1:	Jettison peroxide, Bob.
Rushworth:	I can't hear McKay.
NASA 1:	Jettison everything.
Chase:	Jettison everything, Bob.
Rushworth:	Jettisoning everything.
Chase:	Rog, looks like your jettison is real good, Bob.
Rushworth:	Let me know when its beginning to thin out.
Chase:	Rog.
Chase 2:	I'm on the right side and I got the aircraft in site.
NASA 1:	Bob, check your flap and squat circuit breakers.
Rushworth:	OK, ASAS is disengaged.
NASA 1:	Got your ventral armed and engine master off.
Rushworth:	Master's off.
Chase:	Engine master off, ventral arm off.
Rushworth:	Looks like Lox is about done.
NASA 1:	Bob, stop jettisoning peroxide.
Rushworth:	OK.
Chase:	.......... Pete, you got me?
Rushworth:	I'm going to have to swing around here hard.
Chase:	Rog, bring it around. 25,000, Bob.
Rushworth:	OK, I'm going to use speed brakes, you might go outside of me.
NASA 1:	Remember your ventral, Bob.
Chase:	22,000.
NASA 1:	Bob, check #l APU.
Rushworth:	It's going.
Chase:	Rog, and get your ventral.
Rushworth:	Rog, the ventral.
Chase:	It's off.
Rushworth:	Speed brakes.
Chase:	8,000 (no transmissions coming through)
Chase 2:	NASA 1.
NASA 1:	Roger, Chase 2.
Chase 2:	Airplane has landed, everything OK, real good shape.
NASA 1:	Roger, and ask all concerned to check their mics.
