Bor:ma.n The fuel cell, as Jim said, was an interesting thing.
We finally lost stacks 2A and 20 about the 11th or 12th
day. stack 2B re.mained on and I'm sure there is a
whole history written on the ground of the things they
did and tests they ran at McDonnell when we were in the
air to see just what they could do and how far they could
go with these fuel cells. I thought they did a.n excellent
job,and we ended up being able to run them the whole time.
As a matter of fact, we turned on our Squib batteries about
the 10th day-used the Bua Tie switches and were running
entirely on the f'uel cells the latter part of the flight.
