As a grunt who grew up and became a helicopter pilot, stories like this always make I larf!!
Sarge: OK Boys, choppers are here
Grunt: But Sarge they got no pilots
Sarge: Just Get On! They don't put pilots on 'em when the mission is too dangerous!
Chief: Admiral, your helicopter is here
Admiral: Chief, its got no pilots!
Chief: Don't worry Sir, they don't put them on when the mission is too dull!
Having just seen a very good animated re-enactment of the Sullenberger - Airbus - Hudson - Boat, I can just imagine how that would have turned out with no pilots on board!
