The debriefing began aboard the recovery ship USS Wasp and ended at the Manned Spacecraft Center. In it, astronauts McDivitt and White discuss how the spacecraft systems performed, including the platform, OAMS, RCS and control modes. They also cover operational checks, visual sightings, experiments, mission planning and training, and give recommendations for future crews.

and I flew with it almost the whole flight .
I don't think it was all the way up. The one
thing though--I think the interphone operation
and quality were quite good .
Yes, I thought so too .
We were ready to communicate back and forth. It
was just the way I would liked to have done it .
I thought it was very good. The UH performance at
the countdown was satisfactory and just after we
got into orbit we felt that we had a bit of a
communication loss. We switched to UHF No. 2.
Later during the flight we used both UHF sets and
didn't have any difference in performance from
either one . During the recovery you were using
the UHF primarily. I think you had as much com
munication as you could expect.
That ' s right. I think so too. I do think, though ,
that we had a very bad UHF situation in the first
eight or nine orbits. It was really lousy. As
a matter of fact, I was getting concerned that
maybe we were going to have to land because we
were going to run out of communications .
You were actually working more on this problem
