Whatever happend, it is good they did this now, than on a revenue flight where FL 41 was actually needed.

Ah, finally some logic on this silly thread. Instead of assuming the crew were idiots, maybe there is something that needs to be uncovered in this... and this may be it. I'll bet anyone that very shortly an AD will be issued for the Candair that says the new max cruise is FL390.

I'm thinking mechanical flaw as well. it's darn cold up there, so when you loose the flame that thing cools down rapidly from internal operating temps to -60 in seconds. different metals shrink at different rates, bearings and bushings can seize Any engineering flaws will show up in a hurry.

Or, maybe these guys just didn't know how to restart those engines. You can bet every single piece of those engines will be looked at under a microscope until they find the cause.
