Well according to announcer/commentartor he kept saying over and over again about how fighters gain weight during the flight but I think this has to be something more to do with the way the body handles dehydration in high altitudes. I swore he said fighters can gain five pounds during flight with out eating or drinking a thing. I don't know if this is true or not I guess it could apply but I can't image anyone normal people gaining weight just because they were flying. Imagine how big our flight attendants and pilots would be then. lol
