understand that the actual value was over 7. On the nominal
profile, it i s.
Lovell Was the reentry a little higher than 3.9?
Borman I don ' t know, I doubt if it was, it was so near ful l lift.
Switches and circuit breaker panels. We had a coupl e of
cases knocking of f circuit breakers. We did have one fuel
cell control ci rcuit breaker pop on us twice .
Lovell I am not real sure i t popped. I don' t know whether I hit
it ina.dvertantly twice.
Borman No, you didn't. The second time I watched it pop.
Other than that, I thought the switches and circuit panel s
were well located. I think it i s very important that we
have those guards on there, particularly with changing suits.
Lovell The fuel cel l switches, the power and control switches,
should be LIFT to move switches. They should be over center
locks that you have to lift to move them up. There was a
guard over i t, but still it was so easy to reach up there
and hit those things . I was a l ways worried about throwi ng
the control switch of f, which would have really foul ed up
the fuel cells.
Borman You mean like the squib switches? ...
Lovell Yes , like the squib switches. I think that is the way they
ought to be ~ecause you never touch them unless deliberately.
