nimbus that stands out like a ruler in relation to tpe vertical
plane.
I think it might be here (in the record).
Nordberg - I have seen some of the films.
I don't know if they
were your flight or previous ones.
I am just curious whether the
eye sees something better than what shows up on the color film .
Schirra - Yes, they do .
You use every cue availabl1.
• ·o•Keefe = He doesn't have the stereoscopic effect i p the ordinary
I
sense, but you remember that he is in motion when He sees that the
peak of the clous moves at a different rate so he gets a sort of
pseudo - stereoscopic effect like you get when you are dri ving a long
in a car-- by the fact that they are moving relative to t he capsule .
Schirra - Take page nine here, and put a sheet of paper on the top
of it to cut off the curvature of the earth and you've seen this
from an airplane.
Haven't you?
_Nordberg - Yes .
Schirra - That is why I've used it in this example that I am trying
to get across .
You can see cloud structures in this yellow band
here that are just terrific.
Nordberg - Well, how about at night?
Have you been able to see
any clouds in real darkness at all?
Schirra - Yes, I did and they were lighted by lightning.
In fact
I gave Woomera a report on the first orbit saying I would not
possibly see their flare because I was seeing lightning and they
hadn ' t stepped outside their room .
I said that you are about t o have
some real brutal thunder storms and the second orbit they agreed with
me~ because they were there then .
This was during the night side.
