NASA 1:	OK. We got them full in.
Dana:	Flaps.
Chase:	Flaps.
Dana:	And the gear.
Chase:	Nose gear. About 4, 2, 1, push, pull! That was a beauty, Willy!
Dana:	Yes, that was well controlled, Pedro! My inertial heading is 183. Inertial height is right at zero. Inertial rate of climb is zero. Inertial velocity is zero. X-15 oxygen pressure is 1600. #1 is reading +5 and #2 is reading -40. Hydraulics look good. Control gas is zero. No peroxide low light. Fox source is zero, #1 and #2 are zero.
