NASA 2:	3 g's coming up now. You 're going through 75, 70 in the curve, 60 and you '11 need a left turn after you're level to get into home plate. Have you level at 60. NASA 1, do you have control?
NASA 1:	Rog, have control. Hold your present heading, Bob. We have you high on energy. We have you climbing slightly at 60,000 and the velocity is 2200.

NASA 1:	Rog, thank you, Bob.
White:	...... OK, chase near me, I'd like to go to jettison now.
Chase:	Go ahead, Bob. Got you in site, Bob, got anything you want me to take a look at?
White:	Showing 40,000 feet, how does that look to you guys?
Chase:	About right, Bob.
NASA 1:	Rog, we have you at 40,000 feet on radar, switch your antenna to auto, Bob.
White:	OK, I'm on auto now.
Chase:	Tailing .........
White:	My speed brakes are in, aren't they, as far as you can tell, Joe? .......... just a check.
Chase:	Right, I'm not that close yet.
NASA 1:	Bob, check your peroxide jettison switch off?
White:	Roger, peroxide is off. I got an awful lot of ............
Chase:	What's your heading right now?
White:	I 'm heading 25°. Angling for downwind here, now passing through 31,000.
Chase:	Touching pretty close.
White:	Getting pretty good buffet from about 8° alpha here when I pull up ...........
NASA 1:	Rog, check your ventral armed, Bob.
White:	Ventral is armed and the playback and so far temps are complete.
Chase:	Complete, go ahead.
White:	Just a second, I'll pressurize. I'll have to ace a little speed brake here, you know. Little pieces of glass flaking away.
Chase:	We're at 9000.
White:	I'm turning in here now.
Chase:	Right. Looks good.
White:	I'm back to pressurize. I'll get the ventral on and give you a call. I'm going to be a little low here.
Chase:	OK, speed brakes in.
White:	Yes, they've been in.
Chase:	OK, its away, real clean.
White:	Gear coming down now.
Chase:	OK, BEAUTY!
White:	OK, if you're ready, I'll raise the flaps, speed brakes are full open and I'11 cycle the controls once for you. Push to test on the ball nose. OK, data going off. Hydraulic pressures #1 3200, #2 3400 & temps +50 and +40. H202 tank pressures 560 on #1 and #2. APU bearing temps are 60 and 80. Low light on H202. Helium source pressures 500 on both #1 and #2.
