Here’s what we know: Like an ordinary Boeing 747, Air Force One has three decks and passengers can enter through three doors. Normally, when you see the president in the news getting on and off Air Force One with a wave, he is using the door onto the middle deck and a rolling staircase has been pulled up to the plane. Journalists normally enter through the rear door, where they immediately climb a staircase to the middle deck. They never enter via the main door for security reasons.
