NASA 2:	Roger. Course is looking real good. Got you at 100,000 now, Bob.
White:	OK.
NASA 2:	.......... off, rudder pulse. Put the brakes out anytime you want to now.

NASA 2:	Affirmative.
White:	They're coming out.
NASA 2:	Got you at 5400 feet per/sec about 95,000 feet.
White:	Hope my ventral is armed, I'm reading low.
NASA 2:	Roger. Got you at 90,000 feet, 5000 feet per/sec. About 3 or 4 miles to the right of course. Low on profile at about 81,000 feet. About 4300 feet per/sec, Bob. First 500 feet per/sec now, Bob, at about 78,000 feet, register your pushover, pullup.
White:	.... speed brakes are coming closed.
NASA 2:	Roger.
White:	Pushover, pullup.
NASA 1:	NASA 2, NASA 1 taking control.
NASA 2:	Roger, NASA 1.
White:	Speed brakes coming back open.
NASA 1:	Roger Bob, we have you 2800 feet per/sec, about 2 miles west of course. Coming up on 72,000 at 2800, holding your speed.
White:	OK, dampers are back off. Oh, Good Lord! Hope this one holds. Dampers coming on.
NASA 1:	Bob, we have you at 2000 feet per/sec, 65.
White:	OK, Pal.
NASA 1:	Bob, pull your dive brakes in.
White:	Think I ought to? I'm leaving them out.
NASA 1:	Roger. Coming up on 1300 feet per/sec. 55,000.
White:	Speed brakes are going in. Bob, I'm now going to fly 300 knots indicated air speed. My position, Bob, is north of north lake edge here, about, coming down to 45,000 feet, must be 20 miles north or 10, what is it?
NASA 1:	We have you 20 miles north of the base. You are getting ready to go sub-sonic, 1000 feet per/sec.
White:	Roger. I'm going to ..........
Chase:	OK, Bob, I've got you now.
White:	OK, real fine. I'm flying 300 knots.
Chase:	I'm going to have to scoot out of here, I'll pick you up.
White:	Going to jettison.
Chase:	Roger, you're clear. Negative jettison yet. .......... but that's about it.
White:	OK, I'm going to slow down a little bit, increase my .........
Chase:	Rog. I still haven't seen any jettison to amount to anything, Bob.
White:	Well, OK, we shouldn't have any left. Walt, you're in position, aren't you?
Chase:	Out in front of you, but I've got you in sight.
White:	OK, you stay there. The windshield on the right side, quite awhile ago, completely shattered and if it happens on the left, I'm not going to be able to see much, so stay loose.
Chase:	Roger, you're coming in on the east side of the lake.
White:	Yes, I see where I am, its OK as long as I can see out of the left side. I'll be all right. OK, I'm on pretty high key here. Going back to 300 knots. Master switch is going off.
Chase:	In good position.
White:	Wish I could kick this head bumper up. Oh, there it is. OK, I'm on downwind now. OK, tank handle going to pressurize. My ventral is armed. I hope that inertial indicator of mine was reading low, its a little lower than I'd like. Going to use a little speed brakes here, but don't let me ace you out.
Chase:	OK.
White:	Now when I clear that highway, I'll get rid of the ventral.
Chase:	OK. Did you put the brakes back in?
White:	They're in. Wish I could see out of both sides here.
Chase:	Roll out, now you've got it lined up real good, clear over the highway. Ventral off and clear.
White:	I can only see out of one side.
Chase:	OK, you're a little high yet, flaps. Flaps down, gear, little high, Bob, cut her down.
White:	Yes, I see it.
Chase:	Gear is not down yet. Gear down. About 10 feet, 5, touching down. Very good.
White:	Flaps coming up. Speed brakes are open. One cycle on the controls.
NASA 1:	Roger, Bob, how do you read NASA 1?
White:	Fine. Push to test ball nose. Data off. Hydraulic press and temps are good, 3200 and 3370. Peroxide tank press 550. APU bearing temps are +80 and +80. No low lights. Mixing chamber temps are -10 and -30. #1 and #2 helium source are 1500 or maybe just a little bit less. APU source #1 is 2800 and #2 is 2900. LN2 source 1900. 3-Axis ball heading is 181. Inertial height is 70,000. Inertial climb is 128 per/sec. Velocity is something less than 60 feet per/sec. Oxygen pressure is 1500 psi. Stable platform is off. Speed brakes open. APU's are coming off and I'll close out the rest.
NASA 1:	Roger, real fine flight, Bob, thank you.
