it completely off and later they told us that we
could go a.head and shut it completely off. And
we were sitting in there just shivering and shaking
and I was a lot colder than Pete. He was cold and
I was really cold. I was really thinking seriously
about--if we couldn ' t get that thing warmed up I
was going to take my suit off and I did for a
while in fact ~ake my inlet and exhaust hoses off .
Conrad Yes, that was his answer to the problem. When he
got too cold, just disconnect.
Conrad Just let it blow i nto the cabin.
Cooper But, it was so cold in there that ·ndows froze
over and we were sitting there spinnin@.
Conrad It had a rapid freeze on them. I didn't see that
except when we were doing the high tumqling and i t
got really cold in there . I
Cooper You could see the frost bui ld up on the outside all
over the spacecraft . Outside up o the nose

think to warm up that particular
section. When we damped it immediately thereafter
