24 Conrad • We had some thrust remaining in every axis but yaw l eft . We had some in yaw left if you just wanted to dump raw fuel overboard . I don ' t know whether it was fuel or oxidizer. Cooper Generally, what we'd do is roll and pitch to get our yaw left . Conrad I f we were tumbling and wanted to damp we just waited until we translated into the right axis in whi ch we had some authority . Cooper The one axis that always seemed to work pretty good so far as control authority was pitch. Conrad Yes Cooper Pitch up and pitch down seemed to work reasonably well all the time. Conrad Yes . I wonder i f that had something to do with the pitch thruster lines on the manifold being close to the source. Pitch was always good . Our trouble was mainly coupling in the yaw thrusters both right and left. Cooper Source pressure was easy to monitor . SJurce temper ature we could monitor and it was too CJld .
