FCSD Rep Okay, on this platform alinement thing. You went to
SEF and caged and SEF and Platform Control Mode,
Cooper We pitched down to visual when we went to CAGE and then
went to SEF and we went to Platform mode and after fid
dling around with it awhile we decided the Platform mode
wouldn ' t work so I went to Pulse and then I , just using
my needles , Platform needles then , I just pulsed the er
rors out until we torqued around and got the ... got
it ... on a fine line.
Conrad Okay, Now , there ' s no doubt in my mind that the Primary
Scanners , there ' s no doubt in my mind now, but we lost
on Primary Scanners . We started to aline the primary
Scanners and I don ' t think we ever got to platform aline
correctly because the primary scanners were not working
correctly,
Cooper Now the primary scanners, The funny part of it is the
Primary Scanner was working in such a rr.anner - working
just enough, that it checked right because when we checked
out t he alinement of it and the tolerances on it it was
working fine , but there was something in it on one of
the tests that we did later showed thai it was actually
driving, tending to drive the spacecraft down .
Conrad Continuing to torque you down to about fifteen degrees
nose- down ,
