Any aircraft that has a President ON BOARD, carries the call sign of Air Force One, or Marine One as the Helo, carrying the President, but that Helo is called a White Top, when flying TO THE WHITE HOUSE WITHOUT POTUS. When carrying POTUS, the Marine White Top, becomes Marine One, until POTUS departs, BTW, there are 3 White Tops flying when one has POTUS On board
