Sorry you are wrong on the odds. More like 5 will get you several thousand BA will not do this again. Simply not worth the aggro and the press. Next time it will be a pit stop at JFK. They might do it on another (read no FAA involved) route but not over the land of the free. I have no problem what so ever with the crews call but no way will BA get themselves into this cesspool again.

PS - I'll bet all those BA troopers who got to see scenic whateverstan last week wish they'd had an engine surge versus a bogus warning light.
PPS - Bet the next BA QRH says no diversion to MAN unless one wing leaves the vicinity.
