and Lhat ' "" vision o tside the spacecraft , and I (can make a comparison
betw en those t wo and I have alr eady ; but you can see clearer f rom
outside the spacecraft .
And I was quite surprised at this because
I had thr ee visors on :
one of them was a left-hand visor which

on • t. and Lhen a 1' ex1g ass which is very· l. igh in optical qualities .
And I felt as far as vision was concerned , I could sec better out­
side the spacecraft and I ' d love t o be able to make <•ome fur ther
visua testing out and I think we probably we 1 do this--t ake the
visors
p, this type of work, later on .
So you 're comparing three
ifferent things and I think we can definitely tell you some con-
cl sions between inside and outside as far as Gemini is concerned ,
I ' d L>e very caref\ 1 ap;a.inst sayintJ, that t he vision out of Mercury
was worse or
e1.t r w· th respect. Lo what we could sec out of Gemini
in th
day .
At ni~ht we were ab1c to see and compar e hi gh magni tudes
down to what we felt was 7th order magnitude stare .
(The only thing that )bothers me just a little bit i s you saying because
Gordo said he could - he woke up in the daylight - pointed at the sky, he
could tell whether it was day or night , and t herefore it was an airglow.
Now I could wake up and tell whether it was
ay or ni ght, too, but it
wasn 't b •<;au ae t here was any airglow.
It was because I had sun in the
spa<:c;cr ft .
And I think...... .

So that's the
