By now we all have heard of the presidents trickery in getting onto airforce one and out of the country on thanksgiving. My question though is does anyone know how air force one files their flight plans? especially in cases like this? do they have a discreet permananent squawk code and permitted to fly whereever, or dotheyfile plans like the "rest of us". one would think that a controller would have see the plan on radar and thought something of it the other day. the fact that very few people knew makes me wonder how they pulled it off. VFR in air force one?
