The Pilots may only need to fly a one way mission—on auto-pilot most of the way—How far can a Mig go on one tank of gas? Maybe to Babgdad? Mecca? Cairo? To US ships in Gulf? Isreal? Maybe shoot down a US Plane—maybe Air Force One? Maybe ship it to Mexico—fly it across the border—hit White House? Freedom Tower? Disneyland? las Vegas? New Orleans? Houston? Lots of creative ways to use warplanes.
