I got that feeling when I read Gus and John ' s
debriefing.
Did you?
I didn't.
I got the impression that it
was going to be a much quieter noise.
Well, the whole noise level of the engine girnbal­
ing
was louder than I thought it was going to
be. It surprised me .
Yes. Engine gimbaling was much louder than I
heard before.
We heard this during Wet Mock and
during precount and at midcount.
You can hear
those engines gimbal around; they really shake the
spacecraft.
But, I really wasn't prepared for
the big noise that the prevalves make, and such
a long noise as that fuel gushed down to the
bottom.
I guess that was what it was.
I didn't like t he sounds and vibrations we got
when they raised and
lowered the gantry.
It shook the whole spacecraft.
It shook the whole spacecraft--did you notice how
it never came up straight? The spacecraft was
supposed to line up kind of like this and then
wham!
I had visions of them knocking us off and
laying us flat on the ground before we were
launched,
