NASA 1: Say again your a reading Jack? 
   
McKay: +2-1/2, Bill, and I will leave the sunshade down. 
   
NASA 1: Roger. We'll countdown to 1 minute and the B-52 will go to launch heading at 1 minute. 
   
B-52: Roger. 
   
NASA 1: 003, come 2° right, now. 
   
B-52: Roger. 
   
NASA 1: Standby for countdown. 5, 4, 3, 2, 1, hack. 
   
B-52: Got it and launch master is on. 
   
McKay: Prime. Igniter ready. Precool. Igniter idle. It's looking good up here. Pump. Manifolds coming up. 
   
NASA 1: Looks good here, Jack. 
   
McKay: Slight oscillation. Launch light, 5, 4, 3, 2, 1. 
   
NASA 1: Good light, Jack. Check your b. Check throttle full on, Jack. 
   
McKay: How does my course look, Bill? 
   
NASA 1: Your course looks very good. 
   
McKay: How's my thrust? 
   
NASA 1: We don't have any TM. You're on track. Your profile looks real good. Your heading looks very good, Jack. Coming up on 80,000 feet now. Track looks very good, Jack. Coming up on 110,000 now. Standby for shutdown. OK, Jack, RAS on. Check b to zero. Heading vernier to delta psi. Experiment on, Jack. 
   
McKay: Experiment is on. 
   
NASA 1: Your track and profile are right on the money, Jack. 
   
McKay: On top. 
   
NASA 1: Rog, we show you still climbing just a little. We have you over the top at 257. 
   
McKay: 253 here. 
   
NASA 1: Track and profile are very good.
   
McKay: How's my energy, Bill? 
   
NASA 1: Your energy looks very good, maybe just slightly high. Track looks very good. We have you coming back through 170,000. Experiment to retract. Coming through 150, check your experiment switch to retract, and check your a
   
McKay: Roger. 
   
NASA 1: through 120, RAS off. Coming back through 100, check your a . We have you through 80, standby for H dot. Your H dot looks good, speed brakes to 35. And we want you to come right to a heading of 210. 
   
McKay: What's the heading, Bill? 
   
NASA 1: Come right to 210, Jack. You're just very slightly left of track. Do you have your brakes out, Jack? 
   
McKay: Rog. 
   
NASA 1: OK, keep her coming down, Jack. Have you 15 out at Mach 3. You way want to swing a little to the right and then make a hard left turn. 
   
McKay: Rog. 
   
NASA 1: Keep the nose coming down. 
   
McKay: What's the altitude, Bill? 
   
NASA 1: Have you 65,000. 2.2. 
   
McKay: Brakes coming in. 
   
NASA 1: Bring your speed brakes in, Jack, and swing it hard around to the left. We have you at 17, Jack, if you have time in all this other work you're doing, you might try an aileron and rudder pulse. 
   
McKay: Let me get turned around, Bill. 
   
NASA 1: Rog. Keep her coming around to the left. Still have you at 1.6 Mach number. Looking very nice on your turn to downwind, very nice. We have you coming through 50,000, about 1.5. 
   
Chase: Have you, you can go to jettison. 
   
NASA 1: Go to jettison any time, Jack. 
   
McKay: Rog. 
   
NASA 1: Keep her coming around to the left. You're looking very good. We have you coming through about 45,000. We have you at 1.2. As you go subsonic, let's keep your a down. 
   
Chase: Do you have him yet, Pete? 
   
Chase: Not yet. 
   
NASA 1: Pete, he's headed northbound at the south shore. 
   
Chase: I got him, Bill.
   
McKay: Give me an altitude check. 
   
Chase: 35, Jack. 
   
NASA 1: Check your barometrics, Jack. 
   
McKay: Rog. 
   
NASA 1: Check your flap and squat circuit breakers. You got your stick kicker on, Jack? 
   
McKay: Roger. Circuit breakers are checked. And an altitude check? 
   
Chase: Rog, 28, Jack. 
   
McKay: Is that you, Pete? 
   
Chase: Rog, right to your right. 
   
Chase: You're a little high and a little close, Jack. 
   
McKay: Rog. Lose a little altitude, Pete. Dive brakes. 
   
Chase: Rog, about 23,000. 
   
McKay: I show coming through 20, what do you show? 
   
Chase: Rog, show 20 now. 
   
McKay: Engine master is off, Bill. How do you read me, Bill? 
   
NASA 1: Loud and clear, Jack. 
   
McKay: Dive brake. 
   
Chase: I got them. Looking real good, Jack. 12,000. 
   
McKay: More dive brakes. 
   
Chase: Rog. 
   
McKay: Brakes coming in. 
   
Chase: Rog. Looking real good, Jack. About 4,000 now. Flaps coming down. 
   
McKay: Gear. 
   
Chase: Gear. Main gear is down, I'll call the nose gear. Down and locked, Jack, put her on the ground. About 10 feet, 5, 3, 2, there you go!
