Conrad We didn ' t even check reentry rate command-
Cooper We used direct, UBed pulse . We uned the
rate command . We used hori zon scan .
Conrad I know what it was--why don ' t you tell
them about this--and I ' m going to see if I
can get the fuel f i gures--
Cooper OK. And they all worked very ade quately.
I thought the rate command system, I mean
the RCS system was an excellent system.
It was really crisp and just really, I
thought, it was a real good solid system.
Rate command was much more--
FCSD rep What about the retrof ire - how did i t
hold retrofire?
Cooper Beautifully , it was just no effort at all-
hold--
FCSD rep + 1 degree or less?
Cooper Oh, yeah , easily. We had a little offset
in number 3 and number 4. I could feel
them offsetting us . I just cranked in a
little bit of RCS : Boy, it just glued it
right in there, it just wasn ' t about --
I felt like we could have had four or five
times the offset we had--and never have
,.
