Rushworth:	ASAS is re-armed and lights out.
B-52:	2 minutes now instead of 1-1/2. Holding on heading 180.
Rushworth:	I'd like to push to test the ball nose again, the check didn't look very good.
NASA 1:	It checked good here, Bob.
Rushworth:	OK, I got 2° needle left. My angle of attack is reading just short of 2°.

Rushworth:	I reset roll, I didn't .......... now I've got pitch out again.
NASA 1:	OK, back on ASAS again?
Rushworth:	Roger.
Chase:	Pressure?
Rushworth:	I'm showing 39 or 43, 39 on pressure.
NASA 1:	We have you coming up 41,000 here.
Rushworth:	Chase, I'm going to jettison, over North Base. .......... pump off. Push to test ball nose.
NASA 1:	Have you going through 35,000 feet now north of the base.
Chase:	Tally ho, Bob, I have you.
Rushworth:	Up to 80, 8-1/2 seconds burning on the clock.
NASA 1:	Going through 28,000.
Rushworth:	Showing 25 on the pressure altitude right now.
NASA 1:	Coming up on 20,000. You can pressurize tanks, check your ventral re-armed.
Rushworth:	Going to pressurize. Ventral is armed.
NASA 1:	Get a push to test on the ball nose.
Rushworth:	Yes, I got that at about 30,000.
NASA 1:	How's your #l hydraulics, Bob?
Rushworth:	My #1 is 32.
Chase:	You're clear to drop ventral.
Rushworth:	OK.
Chase:	Ventral away, parachute open.
