It is alleged by a rumour, even though i heard it came from an extremely reliable source...........
The cause of the first and maybe the second engine stopping was a Take Off conducted when the engine temps were already at or over the red line. Something to do with sitting on the ground for 3/4 hour in high 30 degree temps and not enough air into the engine.
Maybe that is why there was sackings walk outs or whatever.
In any case under extreme conditions etc it is always good airmanship to look after the engine, and if that means turning the thing off while sitting on the ground so be it. Taking off when the temps are in the red is not really a nice thing to do to any aircraft.
