McKay:	Roger, I read you loud and clear but a little weak.
B-52:	3 minutes.
McKay:	Reading about 45,000 altitude and 800 feet per second on inertial velocity.
Butchart:	OK, I'm only reading about 6 .......... inertial.
McKay:	APU bearing #1 is a +80, and #2 is a +85. All the pressures look good.
NASA 1:	Do you want to give us a Beta reading, Jack?
NASA 1:	Side slip please.
McKay:	Side slip will be 1° left.
NASA 1:	OK.
B-52:	1 minute 45 seconds.
McKay:	Data on, ball nose, Cine Camera is Cine. Head bumper down,
NASA 1:	What do you read now on alpha, Jack?
McKay:	Alpha is 2°.
B-52:	1 minute.
McKay:	Go to prime. Igniter ready light.
B-52:	40 seconds.
McKay:	Precool. Igniter idle. Lox pump bearing is +10. How does the prime look?
Chase:	Good.
McKay:	Good. Pump idle. Manifolds are coming up. 2nd stage ignition malfunction,
NASA 1:	Try it again. Reset. Prime.
McKay:	Reset.
NASA 1:	Prime.
McKay:	Right.
NASA 1:	OK, go any time.
McKay:	Pump idle. Ready to go, 5, 4, 3, 2, 1, drop.
Chase:	He's away.
McKay:	Alt SAS.
NASA 1:	Back off throttle a little, Jack. Turn about 3 right on your heading, Jack. You're still high on throttle, and you're a little left of course. Back off your throttle a little more. 49 and 50, push over. Do you read me, Jack? You're running a little high, you're through 63,000. Leveling off about 65,000. Going a little high now at 66. OK, 75 seconds, throttle back. Having you running along at 67 now, Jack. 67,000, coming down a little bit through 66.
McKay:	I'm reading 64 inertial.
NASA 1:	OK, velocity looks good at 39. You're a little left to the course, and we have you going down a little now. Have your speed at 4000. We have you coming down a little too fast.
McKay:	Reading zero.
NASA 1:	OK, have you level now. Have burn out, check your yaw damper off.
McKay:	Yaw damper is off.
NASA 1:	Rog.
McKay:	Left pulse and a slight oscillation.
NASA 1:	OK, we're in fairly close. You're coming by 3 Sisters now so we'll reduce the amount of high angle stuff you're going to do.
McKay:	Flaps out 10°.
NASA 1:	And you can swing a little to the right if you like.
McKay:	30°. OK, I have 18, pushing over.
NASA 1:	Rog, have you a little north of Harper's Lake now. Speed's 22. Check your speed brakes to make sure they're both in now.
McKay:	ASAS is armed. A rudder pulse.
NASA 1:	Have you coming down through 55 now, do you have the base in sight?
McKay:	Rog. Pulling a little g.
NASA 1:	Did you get your RAS check, Jack?
McKay:	Affirmative. OK, push down pull up at 1400.
NASA 1:	We'll be coming through to about 46,000 now, Jack.
McKay:	Left roll, right roll. Left yaw, right yaw.
NASA 1:	You got RAS off now, Jack?
McKay:	RAS off at 40,000. Left rudder kick. Going to jettison.
NASA 1:	Rog, you're subsonic now and you can get the push to test and push down pull up at your convenience.
McKay:	Push to test.
Chase:	How does jettison look?
McKay:	Still coming in just a little bit. OK, jettison off.
NASA 1:	Jack, would you leave your handle in jettison till you get below 20.
McKay:	Rog.
Chase:	Still streaming a little.
McKay:	I'm getting a little buffet here.
Chase:	Must be in some rough air here. You're still jettisoning a little bit.
McKay:	OK, 30,000, 10°. Left rudder kick and release. Standby. Yaw damper going off and high key.
NASA 1:	Rog, Jack.
Chase:	27,000, 250 knots.
McKay:	Neil, what do you read on inertial altitude?
NASA 1:	We got 27 now, Jack.
McKay:	OK, I'm reading .......... you're about 8 or 9 above what I was reading here.
Chase:	30,000.
NASA 1:	Go to pressurize, Jack.
McKay:	Going to pressurize.
NASA 1:	Check your ventral armed.
McKay:	My ventral is armed.
Chase:	You made it.
McKay:	OK, starting final.
Chase:	Flaps, gear, 3 good ones, good touchdown.
McKay:	I felt that one! Flaps are up, speed brakes are open. Push to test ball nose. Data coming off. OK, hydraulic pressures are 3350 #1 and #2. H202 tank is #1 2600, #2 2800. APU bearing temp is a +80 #1, #2. The He source is #1 is a 1500, #2 is 1550. APU source pressure #l is 2200, #2 is 2600. Cabin source pressure is 1800. The ball heading is 195. Inertial height is a -1200 feet. Inertial climb is a -50 feet. X-15 oxygen pressure is 1800. Stable platform coming off. Pressure cooling coming off. APU switches.
