Factual error: Just after Carl finds out that Frank has escaped through the plane's lavatory, there is a shot of the plane landing. The plane shown is an Airbus A310, which didn't enter service until 1983, 14 years later. Also, TWA never operated the A310. Later, when Frank climbs out from the landing gear as the plane is taxiing, the aircraft is a Douglas DC-8. (02:00:53)
Factual error: No airport in the world has runway 44. They are numbered 01 to 36.
Factual error: When Carl looks at a map over Europe, the borders of the countries are incorrect at the time: Germany is shown as one country, but it was divided into east and west in the sixties. Czechoslovakia was one country in the sixties, however it was divided into Czechia and Slovakia on the map, as it was at the time the movie was made.
Factual error: In the scene where Frank is tearing up Park Avenue in his "James Bond" sports car, a modern "NYC" lamp post banner is noticeable in the background.
Chosen answer: It is not mentioned, though it is likely Reagan (at the time Washington National) or Dulles, as they both work in Washington DC.
