12 minutes to launch
 

Walker:	.......... reset. Engine reset. We're down at 3600 and 3400 on hydraulics. Control check.
NASA 1:	OK, Joe.
Chase:	Deflection nicely, differential of deflection.
Walker:	Flaps.
Chase:	Flaps starting down.
Walker:	Coming back up and 200 volts on each ....... Platform internal.
B-52:	11 minutes.
Walker:	Data off and MH data on.
NASA 1:	You have the 96 circuit breakers in?
Walker:	Yep. Precool off.
B-52:	10 minutes.
Walker:	.......... showing a 1000 fpm and 45,000. 20 vertical velocity. We're at 2° level. Riding with about 1/2-1° left sideslip and 1-1/2° a.
Butchart:	......... Got a momentary of 41 and cleared itself.
NASA 1:	008, start your turn at 7 unless we call.
B-52:	Roger. Starting turn, 7 minutes.
Butchart:	End of test and end of test light is on ........ any question on 2 and 41 and they were both temporary and cleared themselves.
NASA 1:	OK, got a good check.
Walker:	MH data is off. Have engine oscillograph on.
Butchart:	You are starting to show zero on your stabilizer, Joe.
Walker:	I'm going to replace .......... they never seem to.
Butchart:	Didn't make any difference out here.
NASA 1:	Tighten your turn a little bit, 008.
B-52:	Roger.
Walker:	Aux cabin pressure switch is on. Fire extinguisher auto. Engaging MH-96 MH BCS auto. We're zero on trim Both BCS on. Shows zero and I already got a check, Bob, that we were showing zero outside.
NASA 1:	OK, Joe.
Butchart:	Lube oil showing a 100.
B-52:	5 minutes.
Walker:	On X-15 oxygen, shows about 2700 pounds, and I'm on it. Cabin altitude is 36,000. No ventral.
NASA 1:	Are you still showing left slip, Joe?
Walker:	Yes, that thing shows around 1 or 2 now.
B-52:	4 minutes.
Walker:	Topoff OK, Butch?
Butchart:	OK.
Walker:	Pressurize, wait a minute, data, calibrate, now pressurize. And the two, LOX and ammonia, are in jettison. Peroxide stopped jettisoned.
NASA 1:	Roger.
Walker:	LOX is 50 pounds, ammonia 45 and peroxide tank is 61O. Data off. I'm on X-15 radio, how do you read?
NASA 1:	Read you loud and clear, Joe.
Walker:	Surfaces on the indicator here shows the standard, left one up 1°, right one down 1°. Showing 850 fps and 45,000 feet, ....... zero vertical velocity.
Butchart:	Platform looks good.
Walker:	Bearing temps are 50 and 65.
B-52:	2 minutes.
Walker:	Forward data on, push to test. And we're still indicating l° a and 1-1/2° left sideslip. Cine camera pulse. Head bumper.
B-52:	1 minute.
Walker:	Prime. Igniter ready light.
Chase:	Real good on prime.
B-52:	40 seconds.
Walker:	Precool.
Chase:	Igniter idle flow fine.
Walker:	And we're -4° bearing.
NASA 1:	Igniter idle. Did you call igniter idle, Joe?
Walker:	Affirm. Pump idle, good pump and igniter. OK, here I go!
Chase:	Prime looks good.
NASA 1:	Everything looks good, good chamber pressure. Turn 2 right on the heading. 2° right, Joe. 29, 30, 31 - just a little steep, Joe.
Walker:	OK.
NASA 1:	Everything looks good right now. 61, 62, 100,000.
Walker:	Little fast!
NASA 1:	You say you're a little fast? OK. 75, 76, 77, shutdown, shutdown. OK, Joe.
Walker:	I finally reached the throttle!
NASA 1:	Right. Your course looks good, Joe, and a little bit steep. · psi on, Joe?
Walker:	Roger. I'm also on .......... on RC.
NASA 1:	OK. We're showing a little sideslip going up on the top. Went through 260, 265, you bottomed out surfaces.
Walker:	.......... speed brakes 20°.
NASA 1:	Roger, you are at the top.
Walker:	The moon sure looks pretty.
NASA 1:	Got a good indication on speed brakes. You still got surfaces bottomed out. OK, we have an indication that your sideslip is working now, you can go over to that any time.
Walker:	OK .......... go to standby.
NASA 1:	Everything looks good, little high on energy. 220,000.
Walker:	Left generator going out.
NASA 1:	Roger, Joe.
Walker:	No reset.
NASA 1:	Roger. 180.
Walker:	OK, BCS off, speed brakes out.
NASA 1:	Full speed brakes when you can, Joe, you're a little bit high on energy.
Walker:	Got them full out.
NASA 1:	Roger.
Walker:	Got .......... in site.
NASA 1:	Coming up on Saltdale. When you can, try to reset the alternator.
Walker:	I tried it once already but ........ I do have BCS off.
NASA 1:	Roger. Engine master off?
Walker:	Roger.
NASA 1:	OK, you got the base in site, you can start left.
Walker:	.......... I'm coming up on Santa Fe tracks and I'm 45 left bank, .......... 50,000.
NASA 1:	Roger. Brakes at your discretion now, Joe.
Walker:	I've got them full out here. ..........
NASA 1:	We have you about Mach 1-1/2 here.
Walker:	1 1/2 .......... Close the brakes and crossing 40,000 feet altitude.
NASA 1:	Roger, understand. Everything looks good here.
Walker:	Got .......... set on the generator. Slowing down .......... 300. 30,000 due west of NASA.
NASA 1:	You're subsonic now.
Walker:	I couldn't get my hands on that throttle for beans!
NASA 1:	What do you want to eat beans up there for?
Walker:	.......... Chase 4, do you decide jettison? Coming over main base buildings.
Chase:	What's your altitude, Joe?
Walker:	28,000 feet and 300 knots.
NASA 1:	Check your circuit breakers, Joe.
Walker:	Roger. Both flaps and landing are engaged.
Chase:	Got .......... on you, Joe, have you jettisoned?
NASA 1:	Go ahead to jettison, Joe.
Walker:	Roger.
NASA 1:	Would you reset the alternator again and give it a try.
Walker:	No sale! 19,000 feet and 3018. Pressurize.
NASA 1:	OK, and the squat switch?
Walker:	It is in. Chase, coming 13,000 and 310. Turning base.
NASA 1:	Looks like we're losing #l APU.
Walker:	OK.
NASA 1:	Check your hydraulic pressure #l?
Walker:	It's zero.
NASA 1:	Right.
Walker:	Maybe that accounts for the whole thing.
NASA 1:	No, it just failed, just now.
Walker:	Flaps.
Chase:	Rog, flaps OK.
Walker:	Gear.
Chase:	Got it. OK, .......... 5, 3, 1, good landing.
Walker:	OK, push to test.
NASA 1:	Would you shutoff #l APU, the APU is running.
Walker:	It's off. Data off. 1800 pounds of oxygen. APU tank pressure still holding about 560 on #1 and #2 running nicely at 3300. No low lights on either one and the same tank pressures. Mixing chambers are a -40. Still got 200 pounds showing on engine helium. Helium #1 and #2 are 1200. APU #1 is just under 2000 and #2 is 2300. Cabin source is 1900. 3 axis ball is 176° level, climbing back up to 28,000. About zero velocity and +55 fps.
