The onboard cues for monitoring the el ectrical system are

They came up
with solutions. They evidently were running similar type

f or l onger than they should have.
Fuel cel l operation, as far as I was concerned, Section 1
was i deal. Section 1 maintained its share of the load the
whole flight. Section 2, we lost stacks 2-A and 2-C

But, t he ground came through and read us up a technical
report from St. Louis that explained the whol e thing.
It
made me feel a lot easier when they did that. Rather than
