Countries that implemented the 911 Action - a covert operation with full plausible deniability, seconded professional pilots to the AQ Operation, giving them fake covers so to the US authorities, they looked like students or visa overstayers.
In other words, the pilots were already trained and ready before they arrived here.
Paki Saudi AF pilots?
