the nadir, but I think it wa.s helpful and I think
f l ight proved the same thing that we concluded in
this , that it wa.s a. very simpl e task , once you ha.d
acquired something.. . . . . the track.
Once you ha.d acquired something, yes .
The one thing that I, to this day gave me the funniest
sensations though , is when you track through the nadir
and the things started to speed up and reverse I get
the weirdest sensation that we passed the nadir and
got a.bout 30° going behind us . I almost had myself
reversed in flight, like I wa.s coming up on it again .
Now, I can ' t explain the feeling but it was weird.
It's a real odd optical i llusion where you a.re like
you are in an inverted spin-type situation. You a.re
looking--going back over here and the angle out is
changing such that you al most do have the feeling
that it's - that you have suddenly s tarted changing
your whole angle... .
And if you're looking a.t the nadir, and you're track
ing through in just one axis , pitch or something like
that, invariably you're off a. l ittl e bit in yaw, you
see, and you' ll get going, all of a sudden it will
start speeding up , and if there is any roll in there
a.t a.11; all of a sudden the roll will pick up ,
