Walker:	Data. Tape to 15. Push to test ball nose.
NASA 1:	Joe, we want you to cycle the helium shutoff valve switch.
Walker:	OK, I did it, we're at 2800 on that cabin source.
NASA 1:	Now turn it off.
Walker:	It's off. Cine camera pulse. I'm not using the head bumper.
B-52:	1 minute now..
Walker:	Roger. Prime, igniter ready.
B-52:	40 seconds, Joe. Launch master on, you got the prime.
Walker:	OK, precool is on. Igniter ready is on. I had better shorten up 10 seconds as I did that prime at 50 seconds instead of 40.
NASA 1:	Roger. It's OK, Joe.
Walker:	+10 on the bearing. Pump idle. Ready to launch, GO!
Chase:	You got a light.
Walker:	How's the heading?
NASA 1:	Heading looks right good, Joe. Heading is very good, Joe.
Walker:	Speed brakes.
NASA 1:	Right. Good on speed brakes.
Walker:	Pushover.
NASA 1:	Right on the money. Your profile is very good, Joe. Showing just a little steep now, Joe. Coming up on 46 now and it looks steep. Roger, she's throttling back. 100,000 pushover.
Walker:	OK, I'm pretty burned out.
NASA 1:	Roger, show you about 110 or 111.
Walker:	Roger. Speed brakes closed.
NASA 1:	Roger.
Walker:	Looking good on q, should be about 600.
NASA 1:	Roger. If you get an opportunity along the way, you might make a correction to the left.

NASA 1:	Roger. We want to cross check on hydraulic pressures, Joe.
Walker:	Both 3400.
NASA 1:	Very good.
Walker:	Roger.
NASA 1:	Have you at Cuddeback now. You can go to landing mode.
Walker:	In landing mode.
NASA 1:	Master off.
Walker:	Master off. OK, we will delete the rest of this, I'm too close in.

Walker:	OK, I'm headed for Mojave now.
NASA 1:	Roger, you can bring speed brakes in and start a left turn.
Walker:	OK, ASAS off, and I'll try the yaw and roll off once.
NASA 1:	Roger.
.......... :	There.,
Walker:	.......... back on.
NASA 1:	Roger.
Walker:	Does just like the simulator, it keeps on drifting over.
NASA 1:	Roger. Chase 4, it looks like he will come between Rosamond and Rogers.
Walker:	.......... right over the housing area, and the build-up section.
NASA 1:	Roger.
Walker:	Subsonic at 41,000 and cross check 2000 and Mach 1 by inertial.
NASA 1:	Roger. Ready to go to jettison any time and Chase 4, you are right with him.
Walker:	OK, jettison.
Chase:	Go to jettison, Joe.
Walker:	Landing disengage, energized.
NASA 1:	Roger, we show you about 37,000 right now.
Walker:	I'm reading 33. Little speed brake here.
NASA 1:	You did check flaps and squat circuit breakers?
Walker:	Yep!
NASA 1:	He's about over the east edge of the lake, Russ.
Walker:	Speed brakes closed.
NASA 1:	He's on downwind, Russ.
Walker:	Showing about 310 knots.
NASA 1:	OK, ready to go to pressurize?
Walker:	Pressurize at 17,000. Speed brakes. More speed brakes. They are closed now. More brakes. Flaps and gear. Get that car out of there! I got a little braking action today.
NASA 1:	Very good.
Walker:	Oxygen went off at 1800 pounds. Data is off. Hydraulic pressures both reading 3400. Tank pressures are 550. Hydraulic temperatures +80 and +65. Bearing temperatures are +85 and +50. Mixing chambers -30 on both of them. No low lights. Helium source is flat. #1 and #2 is 1650. #1 APU is 2300 and #2 is 2650. Cabin source is down to 1200. We're heading 178°. Zero thousand feet and zero vertical velocity and zero forward velocity.
