18. Air Force One, United States
While Harrison Ford made gaining entry to the President’s personal Boeing 747 plane look easy in the film Air Force One, getting onboard the real thing is almost impossible to everyone except a lucky few. The flight crew are all veteran Air Force officers with thousands of hours of flying time under their belts and the Secret Service agents on board have had to go through even further background checks than their normal screening usually requires. The features of the plane itself are classified and members of the press have to gain the President’s security detail’s trust for one year before being allowed on board.
