12 minutes to launch
 

Adams:	Both BCS on, data off.
B-52:	11 minutes to launch.
Adams:	Precool switch is off. NASA 1, I don't read you again.
NASA 1:	OK, Mike, we didn't answer. How do you read now? Mike, do you read NASA l?
B-52:	They have answered you twice now, Mike.
Adams:	OK, we got a crummy radio.
NASA 1:	OK, Mike, do you read NASA 1 now?
Adams:	Roger.
NASA 1:	003, come 2° right.
B-52:	2° right at 10 minutes to launch.
Adams:	APU cooling switch normal. Both blowers are still blowers and LN2. Pressure cooling is on. Cabin source is 3500.
NASA 1:	Roger.
Chase:	Have you seen Delamar yet?
B-52:	We saw it on the way up, Don, it looks like the clouds are to the east, we'll have to check it when we roll out on the launch heading.
Chase:	Roger.
NASA 1:	003, we will call the 8 minute point.
B-52:	Roger.
NASA 1:	Come 2° right.
B-52:	035. 9 minutes, Mike.
Adams:	Lox helium shutoff valve is open. Coming on #2 APU.
NASA 1:	Roger.
Chase:	Good.
Adams:	I'll wait for hydraulics, there they come. #l.
NASA 1:	OK, ready for #1.
Adams:	Roger. Generators are reset. Engine reset. #1 hydraulics 3850, #2 is 3400. Electrics look OK. There go the flaps.
NASA 1:	8 minutes, you can start your turn, 003.
Chase:	Flaps coming down.
Adams:	Flaps coming up.
B-52:	Roger.
Chase:	Flaps up.
Adams:	OK, my inertials are looking good. Attitudes looking good. IFDS to internal, got a good light.
NASA 1:	Roger.
Adams:	Computer light, it punched out. Computer still looks good.
NASA 1:	How do you read?
Adams:	Just barely.
B-52:	Reading him pretty well here, Mike.
Adams:	OK.
B-52:	Chase 2, we can't see Delamar now, we will have to take a reading on final approach here.
NASA 1:	Roger. Mike, how are you reading NASA 1 on 286.8?
Adams:	Standing by for 7 minutes.
B-52:	7 minutes now, and, Jack, you were pretty scratchy then. He didn't acknowledge you.
NASA 1:	003, how are you reading this transmitter?
Adams:	#1 mixing chamber is -35, #2 is -45. Aux cabin pressure switch is on. Fire extinguisher auto. I'm going on into my SAS check.
NASA 1:	Roger, Mike, are you reading NASA 1 now?
B-52:	Reading NASA 1, Mike?
Adams:	Negative.
B-52:	Negative, he's not.
NASA 1:	Don, how are you reading NASA l?
Chase:	Fair.
Adams:	Standing by for 6 minutes.
B-52:	There you go, 6 minutes now, Mike.
Adams:	OK, my SAS check is complete. I got hi-lo-hi set in. Roll BCS check.
Chase:	Roger.
Adams:	Rog, and stab position.
Chase:	And you're in trim.
Adams:	Very good.
NASA 1:	Mike, are you reading NASA 1 now?
Adams:	You've picked up a little bit.
NASA 1:	Mike, we're transmitting 279.9 from Beatty/Ely, how do read?
B-52:	5 minutes. And that transmission was terrible, Jack.
Russel:	Lox topoff is complete, Mike.
Adams:	On X-15 oxygen. The pressure is 2600. Cabin altitude is 35.
NASA 1:	Mike, is this transmission any better?
Adams:	I could hear it a little bit.
NASA 1:	Chase 2, keep on with that lakebed weather. 003, are you reading NASA l?
B-52:	Loud and clear.
NASA 1:	Roll out on 213°.
B-52:	213. 4 minutes now.
Adams:	Rog.
NASA 1:	We'll call 4 minutes.
B-52:	Roger.
Adams:	Pressures are coming up. Lox and ammonia 45, going jettison.
NASA 1:	4 minutes now.
Adams:	Back to pressurize. Got 2 switches to jettison. I'm on radio. The MIT is .......... scanning erratically. Back on precision attitudes.
NASA 1:	003, come 2° right.
B-52:	2° right.
Chase 4:	Chase 1, I'm not reading NASA 1 at all.
B-52:	I am, Don. 3 minutes now, Mike.
Adams:	My data is on, so is my tape. No malfunction light. IFDS altitude 44, H dot zero, and velocity is 640.
NASA 1:	Roger, Mike, how do you read NASA 1 now?
Adams:	Reading you pretty weak. #1 APU bearing is 70, #2 is 50. Back to 2 minutes and I think we'll see Delamar in a little bit here.
B-52:	2 minutes here, Mike.
Adams:	Altitude switch is on.
NASA 1:	Mike, you reading NASA 1 any better?
Adams:	a is 2° nose up and b is centered.
NASA 1:	003, come 2° right.
B-52:	2° right. Did you read him then, Mike?
Adams:	Yep!
B-52:	Don?
Chase:	Yes.
Adams:	Standing by for 1 minute hack.
NASA 1:	Roger. Stand by for 1 minute. 1 minute now. Launch heading.
B-52:	Turning good.
Adams:	My tape is on.
Chase:	Delamar is OK, weather is OK.
Adams:	45 seconds, prime switch to prime. Precool, igniter. NASA, I'd like to hear I got a good pump down there.
NASA 1:	Roger.
Adams:	Pump. Pressures coming up. Got igniter. How does it look?
NASA 1:	Looks good. Go ahead.
Adams:	2, 1 LAUNCH. And away we go!
NASA 1:	Good light, Mike. Your heading is looking good, Mike. Standby for theta. Have you on theta. Going just a little to the left, if you can correct 1° to the right. We have you on profile. Going just a little to the left of course, Mike. Profile is looking good. There is 72,000 now. And you are slightly diverging to the left. On course, on profile. There's 93,000. Check your theta, Mike, we have you going just a little low. Standby for shutdown. Have you shutdown. a to zero degrees, Mike.
Adams:	Roger, Jack.
NASA 1:	Have you going just a little low.
Adams:	OK, my theta just slipped off the pad, I don't think it's right in here, Jack.
NASA 1:	Roger. We have you on course. And you're coming up on 160,000 now. OK, do not turn your experiment on.
Adams:	Getting 162 over the top.
NASA 1:	Roger. We had you about 166 on peak there. We have you coming back down. You're diverging just slightly to the right of course now. You're looking very good on energy. Have you at 20° a. Downhill very nicely, Mike. We have you coming up on the profile. OK, have you on the profile. Approaching 100,000. Standby for your H dot. Check your H dot, Mike.
Adams:	Rog, I let my a get a little low there.
NASA 1:	Roger. Have you 4500 and there's 50 miles now. Mach 4. Check your speed brakes.
Adams:	They are out.
NASA 1:	3-1/2 on Mach. You're passing Cuddeback on the right.
Adams:	..........
NASA 1:	Roger. We suggest about 190 on heading. There's Mach 3.
Adams:	I seem a little bit low, I got about 62.
NASA 1:	We have 70 on the altitude. Go with your pressure altimeter, Mike.
Adams:	50 thousand on pressure.
NASA 1:	Roger, we have you at 2.4 and 60,000. Pull your speed brakes in.
Adams:	Coming in. The brakes are in.
NASA 1:	Roger.
Adams:	Standing by for jettison here.
NASA 1:	You're about 1-1/2. Suggest you go to jettison, you're about 10 miles out.
Adams:	OK. Going to jettison now. Got my circuit breakers in. Flaps are checked.
NASA 1:	Roger.
Chase 4:	I have him.
NASA 1:	Chase 4, understand you have him. Up with your window shade, Mike.
Adams:	It's up now. Calling high key at 40 and 1.
NASA 1:	Roger.
Adams:	400 trim (how's my trim) (?)
Chase:	.........
NASA 1:	Mike, can you turn your PMR master switch off?
Adams:	Turn what off, Jack?
NASA 1:	PMR master.
Adams:	Yes.
Chase:	Tally ho!
Adams:	Got about 37,000 feet I guess.
NASA 1:	Roger. Looking in good shape.
Adams:	Yes, it looks OK from here. Little speed brakes.
Chase:	Flap .......... squat, stick kicker?
Adams:	Little speed brakes out. .......... (transmissions garbled from all aircraft)
Chase:	Don't forget your stick kicker.
Adams:	.......... Keep my eyes open. My radio sure sounded bad.
Chase:	.......... OK now. .......... Gear. Both .......... look good.
NASA 1:	Nice flight, Mike.
Adams:	Sliding out to the left.
Chase 2:	Anybody hearing a lot of static on this channel?
Chase 1:	Negative.
NASA 1:	How do you read NASA 1?
Chase 2:	I'm reading you OK, but I'm getting a heck of a lot of noise in the radio here, but I guess it's my receiver.
NASA 1:	Roger.
Adams:	Altitude's 3000. H dot zero. Velocity is zero. Heading is 144. X-15 oxygen pressure is 1800. Hydraulics both 3550. #1 and #2 APU tanks about 550. Fox source is zero. Cabin source 1900. APU source, #1 is 2150, #2 is 2350. #1 APU bearing is 80, #2 is 70. Mixing chamber, #1 is -40 and #2 is -50.
