Neil:	OK.
B-52:	NASA, we'll be dropping about 1500 feet low and about .8 to .81 Mach number.
Neil:	OK, that's an indicated speed or what?
B-52:	Indicated will be around 225 to 230.
Neil:	Good.
B-52:	Get that, Bob?
Rushworth:	Yes, time?
B-52:	Coming up on 2 minutes to launch, right now, Bob.
Rushworth:	OK. Data on. Pushing to test ball nose. Ball nose looks good. Cine camera on pulse. Head bumper coming down. Time, Jack.
B-52:	1 minute to launch. Arm switch, check light checks.
Rushworth:	There went the prime. Action on the gages. Igniter ready light is on.
Neil:	Launch position looks OK from NASA-1.
B-52:	40 seconds.
Rushworth:	Precool is on. Igniter idle on. LOX pump bearing is 2.
B-52:	OK. 20 seconds. 10 seconds.
Rushworth:	Pump idle. .......... back on again. Manifold pressures are up. H2 (?) is up. And launch!
Chase:	You got a light, Bob.
Rushworth:	.......... from the climb angle.
Neil:	Course looks good, Bob.
Rushworth:	OK.
Neil:	30 seconds. Trajectory looks good. 38, 39, pushover.
Rushworth:	0K, pushing over.
Neil:	Looks like you might be a little steep.
Rushworth:	Too high .......... miles.
Neil:	65,000 now. Course is good. OK, you 're coming low now. 65, 68,000, 69, 70 seconds. Coming up through 71,000 now. Check your throttle back and your speed brakes.

Neil:	OK, have the field in sight?
Rushworth:	Yes I do. Seem like kind of a short turning time. I have 46,000 feet. Platform reading 45,000. Snap, crackle, and pop.
Neil:	Say again.
Rushworth:	The engine just snaps, crackles, and pops!
Neil:	Yes, noisy airplane.

Chase:	.......... 8 o'clock.
Rushworth:	Something just went over my top.
Chase:	The one that left a contrail?
Rushworth:	I'm 30,000 feet on high key now. 1 mile out.
Tower:	Altimeter 2996.

Chase:	..........
Rushworth:	Haven't heard from you in a long while, Neil. 24,000 right now.
Chase:	I'm on your right wing.

Neil:	Rog.
Rushworth:	Little speed brakes now.
Neil:	Check your ventral.
Rushworth:	Roger. Ventral armed. Kind of warm in here. Did it clear us?
Chase:	Clear now, you can drop it. Good drop.
Rushworth:	Flaps.
Chase:	Gear .......... good nose gear. 10 feet - 5, 1 - Oh, nice.
Rushworth:	OK, I'm grinding to a halt.
Neil:	Rog.
Rushworth:	Landed a little low. Flaps going up. Speed brakes are open. Going through their cycle. Data off, went through all those checks. Hyd press is 34 on #2 and 3250 on #1. Peroxide tank pressure 560. No rudder in the kick (?) APU bearing temp is 65 on both. Peroxide low lights did come on. Mixing chamber temps 40 on both. Engine helium source about zero on the #1 and #2 is 1500. APU source pressure is #1 26, and #2 28. Cabin source is 18. 3-axis ball heading is 178°. Inertial height 10,000 feet. Rate of climb is zero, velocity is 200 ft/sec. X-15 02 pressure is 1900 pounds. Close speed brakes if they are ready. Stable platform is going off. APU switches are off. Pressure cooling off.
