sure that in case something goes wrong with the thruster,
they could utilize more fuel to keep that alignment.
:Borman Right. Well , as it worked out, we came out all right, any
way. Because we just said we were not going to do anymore
if we got to 5 per cent to 6 per cent. Tb.en they came back
and said that one time, I said, "Well, we're at 6 per cent,"
and they said, "we thought you would go ahead and go to 5
per cent." And this is an awful nebulous thinking.
Lovell Besides the gauge is hard to read to that accuracy .
Borman Th.a.t is r ight. Okey-. We have already discussed, I think,
the consumables on the fuel cells and the batteries. We
turned off the squib batteries, about the 10th~. The
fuel cell consumables were never a problem.
Lovell Main battery voltage was never reall y hi gh, I thought. I
have been led to believe that 22.5 volts was sort of a
