very black star for that one.
They need their heads examined t
I guess we beat that one around pretty well,
didn 't we?
Yes~ The way that we were venting the cabin
was by going to o High Rate and venting the
2
oxygen out through the cabin vent or going to
cabin repress and using up the oxygen through
the cabin and through the cabin vent valve
that way.
I was quite satisfied with the cabin temperature .
It started out and got pretty hot at one time
early in the flight and went up to 100 as you
noted,and then it went back down into the 80's.
I think it actually dropped into the 70's a time
or two.
That ' s right. It was in the 70's most of the
time .
Right.
Let's get the data book , The dry bulb tempera
ture was 80; 80, the first time we tood it.
Then it was 79, 79, 79. Then it was 75, 75,
75, and then they stayed between 75 and 77,I
