NASA 1:	008 and 672, did you get that one minute addition?
B-52:	Roger.
Butchart:	Jack, did you hear my call that I had an overheat warning on the control panel?
NASA 1:	Roger, Butch, got that.
Butchart:	OK. Only showing a -5 on this gyro heat though.
White:	OK, tank pressure came up. LOX steady at 50. And the ammonia at 45.
B-52:	4 minutes.
White:	Did those fall out during the lockout pressures, Jack? OK, 2 jettison switches, the LOX and ammonia are in the jettison position. Intercom switch is off. How do you read me on my radio, Jack?
NASA 1:	5 square.
White:	OK, you got my lockout pressures, didn't you? 50 on LOX and 45 on ammonia.
NASA 1:	Roger, and we got the lockout pressures down here.

NASA 1:	Butch, as far as your control light being on, we'll still go unless something shows up.
B-52:	2 minutes to launch.
White:	OK, both data on, push to test on the ball nose. The a settles down at +1 1/2. Cine camera is going to the pulse position. Head bumper. And still looks good, right?
Butchart:	Looks good on television.
Chase:	Trim is good.
NASA 1:	Bob, everything says go down here.
White:	Good.

NASA 1:	You're on heading, coming up on profile.
White:	Chamber pressure looks good.
NASA 1:	Looking good here.
White:	This sun is awful bright!
NASA 1:	We have you a little tad low on profile, Bob, on heading. 33, 34, 35 seconds.
White:	OK, going to 2°.
NASA 1:	Coming up on profile now. Looking very good at this time.
White:	Rog. Boy, there comes the good old speed!
NASA 1:	Just a little bit steep.
White:	Can you by any chance, see my position?
NASA 1:	Roger.
White:	OK.
NASA 1:	Just a little high. 69, 70, brake. Still a little high, 79.
White:	And shutoff.
NASA 1:	You're looking good on profile. We had you shutdown at 5500 fps, Bob. Just a little left of profile.
White:	OK.
NASA 1:	l10 seconds, Bob.
White:	On reaction controls.
NASA 1:	Roger.
White:	Boy this sun is bright, I mean to tell you!
NASA 1:	You're slightly low on profile.
White:	Switch to delta psi.
NASA 1:	Coming up on 140,000. And 4400 fps. You're slightly fast and low, Bob. Want to standby on delta psi?
White:	..........
NASA 1:	Roger. 4300 fps, coming downhill at 130,000. OK, go to standby on heading vernier, Bob.
White:	OK, I'm back on standby on heading vernier.
NASA 1:	Roger. 115,000.
White:	OK, reaction controls going to auto to off.
NASA 1:	Roger. You're still a little high and fast, 90,000.
White:	OK, I can get 2 g on this profile .......... in the simulator. I'm .......... out there, main thing, to gain stabilizer position, I get 2 g, looks like down there?
NASA 1:	Roger, that looks good here. We have you coming level.
White:	Speed brakes closed. Pulling up.
NASA 1:	3700, and we have your brakes in.
White:	OK, going back open on the brakes.
NASA 1:	Roger, full open. 3200 fps, you're about 20 miles north of high key, Bob. 75,000.
White:	OK. I show 84 inertial.
NASA 1:	Roger, you can swing to the right just a little for a right down-wind.
White:	Yes, looks like I better.
NASA 1:	Roger, it will bring you in on plenty of energy.
White:	I'm showing 2600 fps, how does that compare with your velocity?
NASA 1:	We're reading 2700 here.
White:	What kind of altitude do you show?
NASA 1:	56. When you go to jettison, jettison everything, Bob.
White:	Rog.
Chase:	Are you in a left turn, Bob?
NASA 1:	We have your brakes in and you're looking good.
White:	OK, what is that little humming I'm getting right now in the airplane? Did you see that? Feeling heavy with the speed brakes closed.
NASA 1:	Are your speed brakes completely closed now?
White:	They are. OK, master switch is going off.
NASA 1:	OK, we have you abeam of the south lakebed.
White:	OK, data off?
NASA 1:	1.5 Mach number, soon be going subsonic. Watch your angle of attack.
White:	..........
NASA 1:	Have you coming around very nicely, Bob, at 45,000. Coming transonic, Bob, watch your angle of attack.
White:	..........
NASA 1:	Have you jettisoned yet?
White:	No, I'm right over the south end of the lake, say starting up to north, going to jettison now.
NASA 1:	Roger. Jettison peroxide also unless you have a low light. And engine master off.
White:	Roger, the engine master is off and I'm jettisoning ......... Now passing through 30,000, Chase?
Chase:	I've got you, Bob.
White:	OK. I've rechecked the flap circuit breakers are in. Going to reengage the flap switch to take a look at it. OK, flap switch is engaged.
NASA 1:	We have you in good shape on down-wind, Bob.
White:	I'm now at 25,000. Let me know when I stop jettisoning, .......... flaps ..........
Chase:	..........
White:	OK, I'll wait and jettison in a little bit.
NASA 1:	Peroxide jettison off?
White:	Peroxide jettison is off.
Chase:	..........
White:	OK, I'm now going to pressurize the tanks at 18.
NASA 1:	OK, Bob, we have you pressurizing the tanks, check your flap circuit breaker and MH circuit breaker.
White:	They're both checked. What do you show for altitude, Pete?
Chase:	Got 13 now.
White:	OK, air speed?
Chase:	340.
White:	340? Are you in formation with me?
Chase:	Rog.
White:	That's kind of fast.
Chase:	I'm on the outside of you here.
White:	OK.
Chase:	Want to check here again, you're pretty close?
White:	See you on final. Flaps coming back.
Chase:	They're going back. Back.
White:	Gear coming out now.
Chase:	Main gear out, nose down. 5 feet, 2, very good.
NASA 1:	Real nice flight, Bob.
White:	It looked like it dropped the MH right off the line at touchdown.
NASA 1:	Bob, both your generators still on the line?
White:	Both generators still on the line. MH disengaged. Flaps coming up. Open up the speed brakes. Give a control cycle for you. Push to test on the ball nose. Data coming off. Hydraulic pressure, #1 at 3400 and #2 just about 3300. Hydraulic temperatures, #1 is +40 and #2 is +40. Peroxide tank pressures are 550 on #1 and #2. APU bearing temperatures are +60 on #1 and #2. No low light. Mixing chamber temperatures are -40 and -40. FOX source is zero. Tank pressures are; ammonia and LOX is about 36. Helium tank pressures are #l and #2 are both at 700. Peroxide tank and engine control are setting right about 600. LOX pump bearing is -30. 3 axis ball heading is 186°. Cabin source pressure is 1750. Inertial height is, well it's going up, I don't know what it was at touchdown. Inertial climb is +200. X-15 oxygen pressure is 3000.
