NASA 1:	Good light, Joe. 11 seconds. Coming up on profile, track looking very good, Joe. 29, 30 seconds, on profile.
Walker:	Slow getting to q.
NASA 1:	On track. 70,000. .
Walker:	High!
NASA 1:	Real good track. Coming up on 100 now, Joe. Looking just a little shallow. Showing about 44° on q. 150,000 now.
Walker:	OK, we predict 362.
NASA 1:	Roger. Your track is looking good. OK, track is looking very good, Joe.
Walker:	Roger.
NASA 1:	Looks like you're coming just little low. Showing you little low, Joe.
Walker:	I don't seem to be getting any left BCS roll out of MH.
NASA 1:	Roger. 330,000, 45° bank, b to zero.
NASA 1:	Roger. Manual BCS on, Joe. And we're approaching 350. We're showing about 348 here, Joe.
Walker:	Pretty good.
NASA 1:	Looks like we flew this before, Joe.
Walker:	OK, 20° of speed brake.
NASA 1:	Roger. Track is looking very good. Have you coming just little long, Joe, get set for 26°.
Walker:	OK.
NASA 1:	And we're just little west of track, looking very good.
Walker:	I've got MH BCS off and manual.
NASA 1:	Rog. Roll hold off?

Walker:	Affirm.
NASA 1:	a is looking good, about 22°. Still have you little long. 26° a. 550O fps. 3 g's, 4 g's, showing about 5 g's, Joe. g is looking very good. Mach 4. Check your speed brakes.
Walker:	They're closed.
NASA 1:	Ease it up. OK, have you going just little up hill, Joe. Watch your bounce! Ease it over. Just past China Lake at Mach 3. Have good energy. Push it over. And we have about 75,000 feet. 3000 fps. Do you have the field in site, Joe?
Walker:	Affirm.
NASA 1:	Roger. Have you about 2.8.
Walker:	Rog, I'm coming through 51,000.
NASA 1:	OK, your present heading is looking good, you can make a wide left sweep to disperse energy.
Walker:	Rog, and BCS is off.
NASA 1:	We showed you 60 on our last count. About 2.4.
Walker:	OK, speed brakes. Through 48.
NASA 1:	OK, about 1.4, Joe, are your speed brakes out?
Walker:	Roger. Coming subsonic.
NASA 1:	Coming subsonic, what is your angle of attack?
Walker:	Got about 5°.
NASA 1:	OK. We have your brakes in now.
Walker:	Yep! 300 knots, 33,000 feet.
NASA 1:	Roger. We have you just west of NASA, go to jettison any time.
Walker:	Jettison.
Chase:	Gone to jettison, I can't see you?
Walker:	I'm in jettison now. Coming in over top of tower, crossing runway now.
NASA 1:	OK, check your flap and squat C/B's.
Walker:	Check.
Chase 4:	Has tally ho!
Walker:	Roger. Little speed brake to kill off little more altitude, I'm showing about 22,000.
NASA 1:	Roger. Recheck your flap and squat switch C/B.
Walker:	Rog. Going to pressurize. Small brake and back.
Chase:	3 feet, that was real nice!
NASA 1:	Real good flight, Joe.
Walker:	And I just got #l low light. Heading 172°. 550 fps and 13,000 feet. X-15 O2 off at 1600 pounds. OK, calibrate. Both data off. Hyd pressures, #1 is 34 and #2 is 33. #1 system is 1700, #2 is 2100. Bearing temps are +80 and +115. Peroxide tank pressure still 550. Mixing chambers are -50 and -55. Flat on engine helium. #1 & #2 is 1600. Cabin source is 1900. Platform going off. APU's going off.
