The idea that something like this happened is just not true.  Telemetry
indicated that the ONLY stuck valve, the ONLY stuck valve was in the HELIUM
line.  And it only stuck the one time on the first bird attempt.  The valves
on the NO2 and MMH worked fine.  Or do you doubt the telemetry?
Additionally, then why would the bird continue to work fine for about 24
hours after your scenario.

Richard is right.  This did not happen.
