" orma.n Yes ..here it is here•••it was 158 hours a.nd 27 minutes when
we got up, a.nd we had a. wall temperature of 64 degrees and
a. pilot ha.tch temperature of 66 degrees. Comparing this
with 144 hours and 5~ minutes, the hatch temperature had
been 84 degrees, so there was a. 20 degrees drop du.ring this
one evening. ~ I attributed this, plus the fact th.at we no
ticed la.:rge drift rates when we woke up, to the fact that
the water boiler must have been opera.ting during the night.
It was the only time during the flight that we noticed these
large drops in tempera.ture.•. the very cold wall tempera.tures.
We were on double loop, B pumps most of the time. Finally,
went to A pump twice in the flight when people were in the
suits in order to at~ cool. We went to double A pumps, of
course, when we were powered up.
Lovell We bad one time when we bad one A pump on.
:Borman Twice we had it on.
Lovell Twice, but just one primary pump. We did not go to two A
pumps.

Lovell Right. The second.a.ry loop A pump was not on.
Borman Never on except during periods when the platform we.a running.
Lovell Right.
Borman Now, as I mentioned before, when we were running both B
