Rushworth:	Are you still reading me?
NASA 1:	Loud and clear.
Rushworth:	Pump idle. Manifolds ...... Launch light is on. 3-2-1, launch.
Chase:	Good light.
NASA 1:	Looks good from here Bob.
Rushworth:	Heading of 10°. Went up to 15°.
NASA 1:	Heading is fine. Coming around at 20 seconds now. Profile and track look good. Right on profile. 46, 47, 48 seconds. Have your power reduction at 50%. Speed brakes are open.
Rushworth:	Open now.
NASA 1:	Track and profile are excellent. 65 seconds now, pushover. Good on your pushover. You're a "skosh" bit high on profile. Going just bit high on profile.
Rushworth:	.......
NASA 1:	Tracking above 3,000 feet high on profile.
Rushworth:	.......... shutdown.
NASA 1:	We got your burnout, good. 105,000 feet. Speed brakes should be going in now.
Rushworth:	They're in. Bank angle.
NASA 1:	Track good, your profile, you're going to go slightly below.
Rushworth:	20 and .......
NASA 1:	OK, fine. Your angle of attack, if it comes up, will keep you on profile.
Rushworth:	Yaw off and roll ......
NASA 1:	OK, if it's too bad at high angle of attack, suggest dampers on, and increase a.
Rushworth:	...... 10° roll dampers off. About 9 .......
NASA 1:	Keep angle of attack coming up and you're coming up closer to profile.
Rushworth:	.......... 10° with roll on, 6° now. I'm oscillating with roll off at 10°, going to 15°. .......... angle of attack here.
NASA 1:	Energy is good, no problem there.
Rushworth:	Going to get a pulse here, 10°. .......
NASA 1:	Now crossing profile, start going above it just a bit.
Rushworth:	I'll come down a little bit on angle of attack. ........ pulse, just rolled over again this time.
NASA 1:	We have you at 105,000 coming abeam of Searles Lake. As you can, we will have you start on down.
Rushworth:	My angle of attack is about 12° right now.
NASA 1:	40 miles out at 99,000.
Rushworth:	Getting excursions in sideslip here.
NASA 1:	OK, fine. Have you passing 90,000, use your brakes.
Rushworth:	All dampers back on.
NASA 1:	We have your brakes out.
Rushworth:	Data on, generators.
NASA 1:	Passing 80,000, good, and at Cuddeback. 2600 fps.
Rushworth:	.......... generators.
NASA 1:	OK, call the reset.
Rushworth:	Generators reset.
NASA 1:	Have you at 69,000. Coming through 65,000, velocity 2200.

NASA 1:	Check your #l APU for restart.
Rushworth:	Off and back on again, it didn't start ........
NASA 1:	Your hold modes off?
Rushworth:	Modes are off.
NASA 1:	Energy is good, we'll take a look at systems with you.
Rushworth:	I'm over high key.
NASA 1:	Verify #l APU off, Bob.
Rushworth:	Switch is off and back on again. Want me to leave it on?
NASA 1:	Try to get it back on now.
Chase:	Go to jettison?
Rushworth:	Going to jettison now.
Chase:	What altitude?
Rushworth:	36,000 now and over Silver Lake. #1 APU didn't start.
NASA 1:	OK, you still got one APU. Just come on around the pattern.
Rushworth:	300 knots now at 32,000. 310 knots at 26,000.
NASA 1:	Coming around on downwind. Verify hydraulics on one system and APU looking good there?
Rushworth:	Affirmative. 29,000 turning on high base. 300 knots, full speed brakes out.
Chase:	Got you all right.
NASA 1:	Pressurize tanks, Bob.
Rushworth:	Yes. Flaps coming down. Gear.
Chase:	All down. Looks good. 5, she's on the ground.
NASA 1:	MH system off, Bob.
Rushworth:	It's off.
NASA 1:	You're getting low on LN2 source, we'd like you to expedite APU off.
Rushworth:	OK. (across the board here not using the checklist). No FOX. Tanks zero. .......... zero. #1 and #2 1600. Controls and tanks 600. Manifolds zero. Gains zero. Hyd #1 is 30 and #2 15+. APU #1 zero and #2 is 50. LOX pump bearing +23. Mixing chambers 40. Hyd press 3250 on #2. Peroxide #1 and #2 is 560.
NASA 1:	Put your APU cooling switch in single.
