McKay: Roger, how me? 
   
NASA 1: Loud and clear. Start down hill now, looks real good. Give me a speed reading. 
   
McKay: 4100. 
   
NASA 1: OK, you're high on energy, speed brakes. High on energy and you're 5 Cuddeback. Start a turn to the right, you're just inside the track. Got the field in site? 
   
McKay: Roger. Full speed brakes. 
   
NASA 1: Roger, have you 60,000 feet now. Show you Mach 2.4 at 55,000. Disengage your hold mode. 
   
McKay: OK .......... off.

McKay: OK, going to roll hold. 
   
NASA 1: Speed brakes in. 
   
McKay: Speed brakes. 
   
NASA 1: 40,000. Watch your angle of attack, Jack.

McKay: Ready for jettison? 
   
NASA 1: Go to jettison. Have you picked him up, Chase l? 
   
McKay: .......... 
   
NASA 1: We're showing you about 20,000, Jack. Chase 1, have you picked him up yet? 
   
McKay: OK, I got the flare. 
   
NASA 1: Go to pressurize, Jack. 
   
McKay: Going to pressurize. 
   
NASA 1: Check your brakes in. We're showing light winds at the low level, Jack.
   
McKay: Roger.
   
Chase: I've got 340 indicated, Jack. 
   
McKay: OK, I'm 335, thank you. 
   
Chase: Flaps. 
   
McKay: Flaps. 
   
Chase: Flaps are coming down and coming out good. Gear is down, nose is down good, all 3. 5 feet, 3, 1, very nice. 
   
McKay: Thank you, Don.
