This occurred when the President was set to fly on board Air Force One from Ankara, after attending the NATO summit. Moments after Trump boarded the Boeing 747, he was asked to sneak out of the aircraft in a catering truck to another waiting Boeing 757 (Boeing Air Force C-32A), which then transported him unknowingly to others. The second Air Force One airplane then landed shortly after. It was then somehow arranged, and remains unclear, that the President was then transferred back onto Air Force One before descending the stairs. Trump then spent time greeting the service members before walking towards the new Air Force One airplane.
