# PREFACE

This preliminary transcript was made from voice tape recordings of the GT-5 flight crew debriefing conducted August 30, 1965 thru September 2, 1965 at the Crew Quarters, Cape Kennedy, Florida.

Although all the material contained in this transcript has been edited, the urgent need for the preliminary transcript by mission analysis personnel precluded a thorough editorial review prior to its publication. Errors in this transcript will be corrected as soon as possible and an official transcript will be published at a later date.

By day we used standard procedure of finding a zero yaw, which is a little easier to do down at about retro position. The nose is a little bit in the way for determining zero yaw unless you pitch down just a little past nose low in zero-zero-zero position. When pitched down just a tiny bit, zero yaw was very readily apparent to within a fairly reasonable degree of accuracy, and then ease it right on up. We had lines for the zero-zero position to give us our pitch and roll on the horizon. This was the regular day alinement.

the needles zeroed. It would slowly gyro torque
itself and correct out the small errors for fine
alinement. Anything to add, Pete?

Conrad
Well, I didn't hear all of that, but I think the
alinement is straightforward. One thing I had not
read in either the GT-3 or GT-4 debriefings on
this subject on out the window alinement was that
we have a window gage that you can use that will
put you right on in roll and pitch and, of course,
for yaw you still have to use the same out the
window reference.

Cooper
One thing that I think that should very definitely
training wise be readily …

Conrad Yes

Cooper I think this would be a tremendous benefit and shouldn't be difficult to come up with.

Conrad If you place your eye so that it goes through the lower left corner of the right window or the lower right corner of the left window and run that eye position right through the front RCS yaw thruster, the lower yaw thruster in the front ring, I guess that's ring A, anyway, you take a line between your eye, the corner of the window and the front RCS yaw thruster, right through the middle of it, and put that line on the top of the airglow or the horizon. Then the spac…
