McKay:	Affirm.
NASA 1:	OK, swing it on to the right, you're real high on energy.
McKay:	OK, right.
NASA 1:	We got 4000 fps. Keep the brakes out. OK, we have you at 60,000 feet, 3200. OK, start swinging left now, Jack. You can bring the brakes in a little bit. Bring it on around to the left.

NASA 1:	OK, Jack. You're approaching sub-sonic, watch your a. We have you at 45,000.
McKay:	Dive brakes.
NASA 1:	Coming sub-sonic, watch your a.
McKay:	Roger, 8°, 300 on velocity.
NASA 1:	OK. Chase 3, if you're in position, he's just coming over the southern edge of the lake and we'd like to go to jettison as soon as possible.
Chase 3:	..........
McKay:	Going to jettison.
Chase:	Go to jettison now.
NASA 1:	Have you got the, OK, Jack, brakes out or in and check your squat and flap circuit breakers.
McKay:	Rog, coming up on 20 at 25. What are you reading, Don? Chase 1, what's your altitude?
Chase 3:	I've got him.
NASA 1:	We have you just coming through 20,000, Jack.
McKay:	OK, going to pressurize.
NASA 1:	Affirm to go pressurize.
McKay:	Dive brakes.
NASA 1:	Better get the speed brakes in, Jack.
