l ittle tiny bit . That was showing you that you
weren ' t quite on trim. Then I'd tweek it and it
would sit right there, and it would just start trim-
ming itself out on the ball.
When it trimmed out you damped the rates. You were in
single- ring di rect?
Well , at 400 KI went to single- ring direct .
Yes , we were in pulse
Yes, single- ring pulse .
Single- r i ng pulse to 400 K --
Then I went to RATE COMMAND on the attitude control
selector and took the ACME RCS switch to direct --
one to direct,! the other one was to off. Then I used ,

single- ring direct throughout the ree'.ltry , until
very late when the oscillations got so rapid that 1·

Still one ring?
Still one ring.
We di dn't go on dual- rings until below 70 000 feet .
