Flightrider,
Forgive me if someone has already answered this - can't be bothered to read most of the nonsense on this thread. One thing remains fairly clear to me from my time in the sandpit though - the GF 767s I flew were CF6 engined -about 60K from memory.
A 40k 767 wouldn't get off the ground on a summers day in Bahrain.
But don't let me stop the debate ! ......
Scottie.
