Throttling back earlier should also help this problem. A lower
flow
rate will lead to lower pressure drop along the line, which should
help
the cavitation problem. This might explain why the single CBC had
no
problem.

The CBC core saw the same condition and also shut down early.

But the central CBC on the heavy throttles back much later than than
the CBC on the single. So you get into the regime where you have both
a high flow rate and not much liquid in the tank. All the heavy CBCs
run this way, but the single does not (when the tank is low, it's
running at low flow rates).

The sensor data was not bad - it was reporting exactly what
conditions were.
*All* the flow sensors reported identically.

That's good to know.

After troubles like this, I'm even more amazed they launched the
shuttle manned on the first flight.
