JimJim, Skadi,
I agree with what you are saying, but the design assymetry is only 4kgs to start with. With the ability of fuel to be displaced out of the overflows and from side to side, and with the transfer pumps off, is it totally inconceivable that some combination of manoeuvering/ buffeting caused this to be reduced?
I am looking for a scenario which would have caused the second flameout to have followed very closely on the first, before the pilot had an opportunity to figure out what was going on. It is beginning to feel like a bit of a lost cause, but I am still trying!
