Unless there are world wide 757s available that FedEx isn't scarfing up I don't think the 55s will be replaced. The bus boys think that is what the A330s sitting on the factory show room? I have no real knowledge, just reading the tea leaves like everyone else. As you know, the guys with a real guess ain't say'en.
As far as the -9s, I'm guessing a revolving door in and out of the desert? What happened at the MEC meeting.........have you seen the food fight about updates on the DALPS forum?
