which gave me one little old tweak of suspicion
there that something was wrong right there on the
roll bug. At that point then, I rolled 90 to see
if I could get on that too , the down range needle.
The cross range needle moved in some from the right.
It had been out . . . not completely full scale, but
' I
quite a ways out . It moved in slightly but not
much. Down range needle, let's see , I don't believe
it ever moved up · from there on and then at that
point when I saw that the 90 wasn ' t going to hold it
in there, I said I was going back to the nominal
bank angle. I went back t o the 53 but then put in
60 . . . . 67 degrees bank right, to see if I can get the
roll bug to change . It didn ' t change at that time
so cross range was still indicating that I should
be banked left so I went back to my bank left to
see if I can kill off the cross range. I knew at
that point that something was really seriously
- 0llg and I was just trying to hold it as nominal
as possible . I shoul d have probably at that time
since I was already passed the time of reverse bank
angle, I probably shoul d have gone ahead and hel d
that , but that was a mistake, I probably should have
gone ahead and held that 67 degrees bank right, and
