(Early part of tape missing)
 
Walker: Is that the end, Butch? 
   
Butchart: Affirmative, we got the end of test and it's 0K. 
   
Walker: Data off. 
   
Chase: .......... 
   
Walker: It's about standard, 1 pointer up and 1 down, left and right. 
   
B-52: Passing 7 minutes, starting turn. 
   
NASA 1: Roger, and everything looks good down here on the check, Joe and Butch. 
   
Walker: OK. 
   
B-52: 6 minutes, in the turn. 
   
Walker: Cabin pressure switch is on. Fire extinguisher is auto and engaging MH-96. MH BCS auto. Zero stabilizer, +l on the stick. Both BCS on.
   
NASA 1: Joe, check your #2 generator reset. 
   
Walker: It's on the line, showing about 198 volts. 
   
NASA 1: Roger, thank you. Telemetry problems. 
   
Walker: OK. X-15 oxygen coming on now at about 2500 pounds. 
   
B-52: 5 minutes. 
   
Walker: Cabin altitude is 35,000+. 
   
Butchart: Topoff is complete, Joe. 
   
Walker: OK. 
   
B-52: 4 minutes. 
   
Walker: Data, calibrate. Tank handle to pressurize. Peroxide tank pressure about 605. Ammonia 46 and lox 49. Data off. Interphone off, how do you read me on X-15 radio? 
   
NASA 1: 5 square. 
   
B-52: Rolling out on heading. 
   
Walker: And we show below 45,000 and looks like about 500 on velocity. 
   
B-52: 3 minutes, 7 seconds ago. 
   
Walker: Bearing temperatures are, #1 is 60, and #2 is 80. Time please? 
   
B-52: About 2 minutes, 25 seconds. 2 minutes, Joe and NASA 1. 
   
Walker: Data is on. .......... to 15. Push to test ball nose. Still running about 1-1/2 to 2° left on sideslip and -2 3/4 on a
   
NASA 1: Roger, Joe. 
   
Walker: Cine camera pulse. No head bumper today.
   
NASA 1: You will be in just a little closer than normal, Joe. 
   
B-52: Want me to squeeze the time a little, Joe? 
   
Walker: No, go ahead with the regular count. 
   
Butchart: Platform looks good, Joe. 
   
B-52: 1 minute. 
   
Walker: Prime on. Igniter ready light. 
   
B-52: Master switch is on. 40 seconds.
   
Walker: Precool. Igniter idle. Pump idle. 
   
B-52: 10 seconds. Launch light. 
   
Walker: Here we go, 3, 2, 1. 
   
Chase: Off he goes! 
   
NASA 1: Coming up on profile and heading. 
   
Walker: OK, my needle went haywire so I'll have to fly by the ball! 
   
NASA 1: Roger. You're on course. 57,000, Joe. Looking good. Just a little slow, Joe, but on profile. 
   
Walker: Running about 580. 
   
NASA 1: On heading and looking good. 70,000. You're going a little high on profile, Joe, but on heading. Mach 5, Joe, shutdown. Coming up on 90,000. We show you about 5.3 on Mach number. Still Mach 5, Joe. We don't show any dive brakes. 
   
Walker: OK. 
   
NASA 1: Give us brakes, Joe. Have you high on energy. 
   
Walker: I have the field in site. 
   
NASA 1: You're coming up along Cuddeback now. Going to be high on energy. Watch your q, Joe. 
   
Walker: Got 1450. 
   
NASA 1: We have you at 1650. Passing Cuddeback now. Have about 18 out now, you can use your dive brakes at discretion. 
   
Walker: Rog. 
   
NASA 1: Do you have the field in site, Joe? 
   
Walker: Rog. 
   
NASA 1: Looking good. 
   
Walker: Showing about 1.5, coming in on the brakes.
   
NASA 1: Roger, that's a good call. We have you about 35,000. Go to jettison anytime. 
   
Chase 4: OK, picked you up. 
   
Walker: 29,O00. 
   
Sport: X-15 is in a left turn, coming about 3 miles north of housing area, about 26,000. 
   
Walker: I'm showing 25 and 300 knots. 
   
Sport: X-15 is about 2 miles west of NASA now. 
   
Walker: Pressurize. 
   
NASA 1: Roger. 
   
Chase: On downwind, Joe? 
   
Walker: Yep. Flap breakers checked and landing disengage in. 
   
Sport: North edge of the lake now. X-15 is at 17,000 now. 
   
Walker: I'm showing about 14, 13. 
   
NASA 1: We show you just a little low on downwind, Joe. 
   
Walker: Face plate. Flaps. 
   
Chase: Flaps and gear, 10 feet, 5. 
   
NASA 1: Looks like a goody, Joe. 
   
Walker: I can't imagine how that presentation went out, but it sure ran me high! 
   
NASA 1: You were high on energy, low on Mach number, just about throughout your flight plan. 
   
Walker: Yep. Going on another cross-country out here. 3400 on #1 and 3300 on #2 hydraulic pressure. Bearing temps are both +60. Peroxide tank pressure both 560. No peroxide low lights. Mixing chambers, #l is bounced up out of site on the top side and #2 is -40. Engine helium source is zero. #1 is 1350 and #2 is 1350. #1 APU is 2200 and #2 is 2300. Cabin source is 1500. 3 axis ball heading is 140°. Inertial height is 16,000, +20 fps. Inertial climb is zero. Oxygen pressure is about 1150.
