Russel:	Internal now.
McKay:	Internal now, Jack.
Russel:	Rog, starting analyzer check.
McKay:	Did you call the 11 minute point, Charlie?
B-52:	Rog, we're coming up 10 very shortly.
McKay:	Precool off.
NASA 1:	003, NASA 1 is going to slip a minute in on you, will call 11 minutes shortly.
B-52:	Roger.
Russel:	My doppler velocity is still holding same, 940 - 950 area.
NASA 1:	Roger.

NASA 1:	8 minutes now.
B-52:	Roger, is this level at 450 and then cleared to turn.
NASA 1:	Affirmative.
McKay:	Mixing chambers -35 on #1 and #2.
NASA 1:	Roger.
Chase:	Your trim looks good, Jack.
McKay:	Thank you, Bob.
NASA 1:	Chase 4, you're very weak.
McKay:	How does the launch lake look to you, Bob?
Chase:	There's a cloud at the upper end of the lake, Jack, when we came down it, however the approach from the south or north ....... I'll have to check it going the other way.
Chase 2:	I'm right beside it here and it looks like the best approach is to the west. How far are we from launch?
NASA 1:	7 minutes. We'll call this the 7 minute point. We will call this 6 minutes.
B-52:	Roger.
NASA 1:	6 minutes now.
McKay:	Aux cabin pressure switch on. Delete the blood pressure. Fire extinguisher auto.
NASA 1:	Roger.

NASA 1:	003, we'll call 2 minutes.
B-52:	Roger.
McKay:	APU bearing temp is -50 on #1 and #2, correction +50.
Chase:	Jack, you can take a look out there and see the lake, it's right under that cloud now and it looks like the best approach will be from the southwest.
McKay:	Roger. Delta psi standby.
NASA 1:	003, 2 minutes now.
McKay:	Data on. Oscillograph on. Experiment on. Push to test ball nose.
Russel:	Doppler velocity 684.

NASA 1:	1 minute now.
B-52:	Roger.
McKay:	1 minute. Prime. Igniter ready light.
Chase:	Came on and went off.
McKay:	Prime switch is on. Precool. Got an igniter ready light. Igniter idle.
Russel:	Launch light, Jack?
Chase:	Let's have a launch light, Jack.
McKay:	I'll get it off until I'm ready here. Pump. Manifolds look 275, roll hold on.
NASA 1:	Good igniter.
McKay:	Everything's looking good, NASA l?
NASA 1:	Roll hold on, Jack.
McKay:	Roll on. 3, 2, 1, launch.
NASA 1:	Good light, Jack. Keep your a up, Jack.
Chase:	Got a good light.
NASA 1:	Watch your a, Jack. a looks good.
McKay:	Roger. How's my heading?
NASA 1:	Track looks good, Jack. Keep your a up. Coming up on theta. Profile looks good. Track looks good. Profile looks good. Coming up on 80 now. Track looks good, Jack. Profile is right on. Coming up on 100,000 now. Track looks good, 120 now. Standby for shutdown. Push over to zero a. Shut off the engine. Engine master off.
McKay:	Engine is off.
NASA 1:	Check your trim, Jack. Bring your angle of attack down to zero. And you're going through 200,000, Jack, heading to vernier psi . Going a little high, Jack, we'll call your peak altitude to you. Check your trim, Jack. OK, we show you coming over the top, 285 or a little more. How do you read, Jack?
McKay:	5 square, how me?
NASA 1:	Mighty fine, Jack. Let's get the speed brakes to 20°.
Chase:	Is he on track, NASA l?
NASA 1:	Check your theta, Jack. You went a little high on this profile, we're going to have to hold 24° of a coming in, in order not to over q the airplane. 672, do you read NASA l?
McKay:	5 square, Bill, how me?
NASA 1:	5 square, Jack. We're going to want 24° of a and 5 g's on this reentry.
McKay:	Roger.
NASA 1:	And we're going to have to hold the 5.
McKay:	Little speed brakes.
NASA 1:	Jack, you will be quite a bit right of track, which is good because you're quite a bit long on energy, so on your reentry you will have to make a hard left turn back to the field. We will advise. Bring in the speed brakes just a "tad" and turn your heading vernier to standby. Check your a, Jack.
McKay:	Reading 24°.
NASA 1:	Mighty fine, Jack. We have you coming through 160,000. Angle of attack looks good. Keep your angle of attack up. 24°. Keep your angle of attack up, Jack, until you get 5 g's. OK. Keep coming down, watch your H dot. And start a hard left turn, Jack, you're OK. Your H dot looks good. A hard left turn, Jack.
McKay:	Left turn.
NASA 1:	And roll hold off. Jack, let's make a hard left turn here. Let's pull out full speed brakes. Disregard that, Jack, that was my error, let's use no speed brakes in the turn. We have you at Mach 3, Jack. OK, really bend it in to the left and do not use speed brakes. We have you coming through 25 on velocity. Keep her coming around to the left. Do you have the field in site?
McKay:	Yep!
NASA 1:	Mighty fine. We have you about Mach 2 at 60,000. About 10 west of Mojave.
McKay:	Real ........ Ready to jettison any time.
NASA 1:	Roger. Set up an H dot of about 250 fps.
McKay:	OK, I got it. .......... fuel 400.
NASA 1:	Go to jettison whenever the chase is ready to start looking for you, Jack.
McKay:	.......... direction .......... wind ..........
NASA 1:	The wind is 260 at 20 knots.
McKay:	Roger.
NASA 1:	Do you have the field in site?
McKay:	Roger.
NASA 1:	You're coming subsonic, don't let your a get too high.
McKay:	Give me an altitude check, Bill.
NASA 1:	OK, we have you coming through 50 now and you might check your barometric, see how its looking. Jack, will you turn your peroxide jettison switch on?
McKay:	Roger, peroxide jettison switch is on. .......... is 9°. Altitude 40 indicated ....... Little speed brakes.
NASA 1:	When its convenient, will you check your squat and flap circuit breakers.
McKay:	Roger.
NASA 1:	And check your trim zero. Jack, will you confirm you checked your trim zero?
McKay:	Altitude?
Chase:	Coming through 30,000 now, Jack.
McKay:	OK, starting in.
Chase:	25,000.
McKay:	.......... horizontal check?
Chase:	Roger, they're trim, do you read?
McKay:	Roger.
Chase:	And 371 velocity.
McKay:	Brake. And I'll take a smoke bomb any time.
Chase:	I got 10,000, Jack, and 370.
McKay:	Roger.
Chase:	Looking real good. 7,000 and 340.
McKay:	Another altitude?
Chase:	OK, coming through 5,000 now. 340 on velocity.
McKay:	And the smoke bomb, OK, there it is!
Chase:	320. 300. Put your flaps out. Coming down, very good. And get your gear, Jack. OK, 2 good ones, nose coming. Nose is coming down. 4 feet, 2, 1, beauty!
