I'm with Hold West. I recall the Aeromexico event, and wish to point out a third set of eyeballs didn't help them, eh?
Postscript: I also recall that one airline (possibly Aeromexico?) was chastized for removing the fins/strakes on #1 and #3 nacelles - ostensibly to prevent techs from parking their hand tools there. These strakes have a significant effect on stall characteristics. Somehow I doubt that removal of strakes is the case with FedEx, though.
