Chase:	Looks good, pull her up.
NASA 1:	590 on chamber pressure. 15 seconds. Come right 2° on heading at 24 seconds. 30 seconds.
McKay:	Speed brakes.
NASA 1:	38 seconds. Retract your speed brakes a tad, we've got 30° and if you can, correct 2° right, we'd like it.
McKay:	Pushover.
NASA 1:	We still want 20° speed brakes. Altitude, profile is good. 0K. Little more speed brake and little more right turn. That's good. You're going high and we're approaching 80 seconds.
McKay:	Shutdown .........
NASA 1:	Stay in your right turn. Close your speed brakes. About 120,000. Correct your heading to the right, add 5°. Pick up your theta, you have an entry to make. Right over Hidden Hills.
McKay:	400. Little yaw.
NASA 1:	Hear you fine. Have you drifting still to the left of course, want to make a right turn of about 10°.
McKay:	Roger.
NASA 1:	And recommended inbound heading at this point is 230.
McKay:	Little yaw there (?) Went upon roll, piped out (?) How's my theta?
NASA 1:	Says zero here, and you're level at 70,000 and 3-1/2 Mach number, coming up on 3 Sisters.
McKay:	Speed brakes.
NASA 1:	Have you at 2.9 Mach number about 10 west of 3 Sisters.
McKay:	RAS mode off.
NASA 1:	RAS check? Are you able to do a RAS check?
McKay:	Roger, getting it, Joe.
NASA 1:	Mach 2 and 55,000. Test mode landing.
McKay:	Test mode to land. Just got some music in the background here.
NASA 1:	I don't know, that might be the cheering in Brisbane or someplace.
McKay:	OK, brakes in.
NASA 1:	Have you 1.3 Mach number and 10 north of North Base at 48,000.
McKay:	What's the altitude?
NASA 1:	Coming up on 45 now.
McKay:	OK, RAS coming off.
NASA 1:	You an pull around tighter in your turn.
McKay:	OK, I'm reading 52.
NASA 1:	We're showing 42. Master switch off and jettison at your desire.
McKay:	Going to jettison.
NASA 1:	0K, and RAS off. Flap and squat circuit breakers in.
Chase 4:	Tally Ho!
McKay:	Rog.
Chase:	You're jettisoning, Jack.
McKay:	Little speed brake.
Chase:	Jettison stopped.
McKay:	Understand jettison stopped. Got me, Danny?
Chase:	A-OK, 215.
McKay:	OK, I'm reading 29 on inertial right now.
NASA 1:	How about your pressure?
McKay:	Going to pressurize.
NASA 1:	I mean your pressure altimeter?
McKay:	Coming up on 10 now.
Chase:	10,000.
NASA 1:	We show a little speed brake.
McKay:	Just a tad, coming in. Flaps.
Chase:	Flaps coming down. Gear coming down. 10, 5, '2. Your nose wheel looks cocked, straighten down.
McKay:	Looks like I saw some rubber flying there!
Chase:	Your nose wheel was cocked to the right, about 20°.
McKay:	OK. Looked like a good one to me! OK, I think we lost the nose wheel there, Joe.
NASA 1:	OK, you're in good shape though?
McKay:	Roger. I kept the canopy on this time, incidentally.
NASA 1:	Shutdown #1 APU now and expedite your postflight checks.
McKay:	#1 APU is out. Pressure on #1 is 3450. Peroxide tank pressure's holding at 550. APU bearing temp is +30 on each one. Mixing chambers are -38 on #1 and -40 on #2. Helium source pressures are #1, 60, and #2, 50. APU source #l is 1850, #2 is 2500 Cabin source is 1500. 3 axis ball reading, heading 200°. Reading about 500 fps climb and 800 on velocity, 2600 on inertial. X-15 oxygen pressure is 1500.
