Rushworth:	Roger.
NASA 1:	70,000. We have you just a little low. Standby for speed brakes. Showing you several thousand feet low.
Rushworth:	Shutdown.
NASA 1:	Shutdown and pull your brakes in. We have you still a little low, Bob, on track. Got a good 5200, Bob. Peaking at 93,000.

NASA 1:	Roger. On track, coming up on profile now. 500 "q", watch your H dot.
Rushworth:	Roger.
NASA 1:	45 on velocity. Just slightly above profile. Real nice track. Check your H dot. Coming over Racetrack now, Bob. Your velocities are good, your altitude is good, on track. Check your H dot.
Rushworth:	What's my altitude, Jack?
NASA 1:	86,000. 43 on velocity and bring it up, Bob. Bring your nose up. Have you coming down. 41 on velocity.
Rushworth:	OK, my ............
NASA 1:	Roger, pull it up, Bob, pull it up. Pull your H dot up, Bob.
Rushworth:	Can't see .......... lot of sideslip this time.
NASA 1:	Roger, you're coming in very weak. Get your altitude up. Dampers back on and brakes in, Bob.
Rushworth:	Rog.
NASA 1:	700 q. Roger, 35, and lets get the q down.
Rushworth:	I'm trying.
NASA 1:	You're in good shape, get your "q" down if you can. 31. Chase 4, hold on, we want you around in a minute.
Chase 4:	Roger, what's his position on the ground?
NASA 1:	We have him coming just west of Searles. 53 miles out now, Bob.
Rushworth:	How many?
NASA 1:	50 miles, 26 on velocity. Lets come right 10°, Bob.
Rushworth:	Roger.
NASA 1:	Check your H dot and forget the rest of the plan. 23 on velocity. OK, we have you 200 "q" and start back down now. Do you have the field in site?
Rushworth:	Not yet.
NASA 1:	OK, probably out your right window over your nose, you'll be coming up on Cuddeback here. Come right. 76,000. Mach 2. If your H dot is working, 300 feet down hill. 300 "q." Do you have the field in site?
Rushworth:	Yes, I've got it in site. Having an awful time tracking.
NASA 1:	Roger.
Chase:	Have you passed Cuddeback yet?
NASA 1:	Rog, he's just southwest of Cuddeback now, Joe. Have you 18 north at 1.8.
Rushworth:	.......... quite a little bit strange here, Joe, can you get in here as quick as possible?
Chase:	Right.
NASA 1:	1.4 on velocity. Max L/D, Bob, 240.
Rushworth:	I'm holding an awful lot of wing in.
NASA 1:	What do you think came out?
Rushworth:	I don't have any idea. It felt like the gear again.
NASA 1:	8 miles out at 1.2, watch your a, Bob.
Chase 4:	Has a tally!
NASA 1:	Chase 4 has him, thank you.
Rushworth:	What's my altitude now, Jack?
NASA 1:	45,000.
Rushworth:	Going jettison. Am I over the field yet?
NASA 1:	Coming up on the highway now, Bob.
Rushworth:	Roger. Who was talking then?
Chase 4:	Chase 4.
Rushworth:	What's out?
Chase:	I'm not close enough yet - the nose gear is not out.
Rushworth:	OK.
NASA 1:	Over edge of lake at 38,000.
Rushworth:	Something is real weird.
NASA 1:	Hi key, Bob, at 36,000, you're in good shape for 18.
Chase:	33,000, Bob, and your right main gear is out.
Rushworth:	OK, what does it look like?
Chase:	I'm coming in now to look.
NASA 1:	Stop jettison, Bob. Stop jettison on peroxide.
Rushworth:	Jack, go to another transmitter, you're breaking up.
Chase:	Stop jettison on peroxide, Bob.
Rushworth:	Rog.
Chase:	It looks to be down in a normal position.
Rushworth:	Is the skid level?
Chase:	Roger, it looks just about like in landing position.
Rushworth:	OK.
NASA 1:	Joe, can you see the drag link?
Chase:	Roger, drag link looks OK as far as I can tell now.
NASA 1:	Bob, your gear had come out at around 600 "q."
Rushworth:	Go to another transmitter, Jack. OK, I'm starting in. Little bit high, little speed brakes.
Chase:	That's all right.
NASA 1:	Suggest you put the gear out a little higher, Bob, give you plenty of time.
Rushworth:	Roger.
NASA 1:	Chase, check both drag links when he puts the gear down, if you can.
Chase:	Right drag link looks OK, Bob.
Rushworth:	OK.
NASA 1:	Still have brakes out, Bob.
Rushworth:	Speed brakes coming in.
NASA 1:	Go to pressurize. Bob, you can give a push maneuver on landing with ...... in it.
Rushworth:	Roger. Flap.
NASA 1:	Check your circuit breakers.
Chase:	Flaps are coming.
Rushworth:	Gear.
Chase:	Roger. They look good. 2 feet, 1, beautiful, you're down, it's OK, you're holding. Good show, Bob.
Rushworth:	Boy, I'll tell you, I've had enough of this.
NASA 1:	You and me both, Bob. Very good flight.
Rushworth:	Jack, try another transmitter, that one is lousy also.
NASA 1:	Roger, Bob, we've been all over the circuit here. Let us know when they stopped.
Rushworth:	They stopped at 2279, Jack.
NASA 1:	Go to cage and standby on your Tracker.
Rushworth:	OK, I never did get to turn that on, its on cage now and going to standby. 3 axis ball heading is 176. Inertial height 22,000. Inertial climb little above zero. Speed is normal. Oxygen pressure is 2000. Hydraulic pressures, #l is 35, #2 is 3350. Peroxide tank pressure, I'll just go across the board, it's easier. Sources, #1 and #2 is 600 pounds. Control is the same. Cabin source 2150. APU source, #1 is 26, #2 is 28. APU bearing temps, #1 is 80, #2 is 60. Mixing chambers, #1 is -45, #2 is -40. Voltage still good.
