There are currently two Air Force One jets in use, one with the tail number 28000 and the other with tail number 29000.
There are 2
B-747's usually used as Airforce One.
ANY Air Force plane that is carrying the President is Air Force 1. His
USUAL helicopters are called Marine One. When Bush landed on the carrier after the Iraq invasion it (the plane) was Navy One. The carrier itself
MAY have been re-designated after touchdown.
