just what can Air Force One do?

in various Hollywood films the Air Force One plane has a lot of functions that i wonder if theyre on the real one. in the recent edition of Air Force Monthly mag, the E-4 article was good. yet i was still left asking questions. in the film Air Force One, the E-4 has a rear door that can be used for parachuting out, does the real AF1 have such a rear door that can be used for parachuting in an emergency? also the plane is shown with a pod that the president can use in an emergency to be ejected and parachuted to earth? is this really possible, does AF1 carry such a pod internally, has any plane ever had such a pod on board? and what if a missile is fired at the plane, can AF1 avoid a good radar missile like an AMRAAM? any info would be helpful :dev2:
