Air Force One

Air Force One was the aircraft used by the President of the United States. President Winters used it to visit Great Britain to discuss the Toclafane with British Prime Minister "Harold Saxon".

It was a massive jumbo jet with highly distinctive markings. The jet was dominated by a sky blue undercarriage, which was separated from a darker blue-and-white design by a ribbon of gold and white that ran the length of the plane. The design was set off by the Presidential Seal of Office, as well as the words "United States of America" in a simple, serif font. (DW: The Sound of Drums)

Behind the scenes
In the real world, Air Force One is not a particular plane, but rather the call sign of whatever US Air Force plane the President of the United States happens to be flying. The DWU has never actually made this distinction, which was broadly popularised by the movie Air Force One and the television series, The West Wing.
