NASA 1:	OK, go ahead.
.......... :	NASA 5 Mobile ..........
NASA 1:	Got a good light, Milt. OK, you're on heading, have you coming up on profile. Standby for theta now, Milt.
Thompson:	OK, my clock didn't start.
NASA 1:	OK, we'll give you the times. Standby for pushover now. Standby for speed brakes now. How do you read NASA l?
Thompson:	Affirm.
NASA 1:	You have your speed brakes?
Thompson:	Affirm.
NASA 1:	Coming up on 80,000 now. You're just a little left of course. On profile. Standby for 90,000 now. We have you parallel to the course, just to the left. Your profile is looking good. Shutdown. Bring your speed brakes in, Milt.
Thompson:	OK.
NASA 1:	We have you just parallel of profile, just slightly under.
Thompson:	Roger.
NASA 1:	5150 on velocity, shutdown, Milt. We have 104,000. Right on profile.
Thompson:	OK.
NASA 1:	Check your H dot and set up your rate of descent. Check your ang of attack. We have you about 3 miles left of course, you're looking very good right now. 49 on velocity. Just above profile, Milt. We have you at 100,000 feet, you can start bringing it down just a little. Check your Hdot.
Thompson:	OK, Jack.
NASA 1:	47 on velocity. Have you coming down very nicely, Milt. You're paralleling the profile very nicely. Slightly above, but very good. Check your rate of descent, pull it up just a little.
Thompson:	OK.
NASA 1:	90,000 now. 44 on velocity. When you can, pull 3° to the right, Milt.
Thompson:	Rog.
NASA 1:	We have you coming down through the profile now, check your rate of descent, just slightly. Mach 4, energy is looking very good. Have you little behind on energy, just like the simulator, Milt.
Thompson:	OK.
NASA 1:	You're on profile, very nicely, keep up your rate of descent what you have now. Field is straight ahead, you can come right another 5° if you like.
Thompson:	OK.
NASA 1:	You're doing 80,000 now, going just slightly above profile. 36 on velocity. Standby for 50 mile point, Milt.
Thompson:	OK.

Thompson:	OK.
NASA 1:	Mach 3, Milt. Coming down under the profile just a little, you can bring it up. Point 8 on the Mach number. Have you just under energy, you have plenty. 2-1/2 on velocity. What is your dynamic pressure?
Thompson:	It's about 500.
NASA 1:	That's what we're reading. OK, you're abeam Cuddeback. The field is straight ahead. Why don't you turn right just a little.
Thompson:	OK.
NASA 1:	22 on the Mach number. You can pull your dampers back on here.
Thompson:	OK, they're on.
NASA 1:	OK.
Thompson:	Want the speed brakes yet?

Thompson:	Rog.
Chase:	10,000 and about 330.
Thompson:	OK.
NASA 1:	Milt, check your flap and squat circuit breakers.
Thompson:	They're in, Jack.
Chase:	About 350 indicating now.
Thompson:	OK.
Chase:	Got your flaps?
Thompson:	Flaps.
Chase:	Flaps are coming. There's 300.
Thompson:	Gear.

Thompson:	"By God," Ron, we did it!!
NASA 1:	Ron is laying on the floor, he's in a dead faint right now!
