At the end of the movie, when Tom Cruise is on the elevator with the director of LE, they are going "up", but after a while look at the scenery, and it doesn't change. It looks as if they are going up, but the scenery is the same so how can they be going up?
Have you ever been on an airplane? As you go higher and higher, the scene does not appear to change nearly as much as it did during the initial ascent. The change becomes exponentially less the higher you go. Maybe that is what is happening in the elevator here. It certainly seems to be an absurd amount of floors up, judging by the number of walls between the glass panels that overlook the city. The title of this scene is also, "Ladies and gentlemen, we are no floating in space." Maybe it was the director's intention.
