Everything photographed at a distance looks 2-D. Remember the old TV images of football games where the people in the foreground seemed the same size as the people in the background? At long distance, everything looks to be the same distance. Just a fact of photography. Thus also, no change in perspective. How could there be?
But it was a handheld camera. The line of sight does move around a bit if you watch the complete video at true speed. No reason to expect wobble, if the guy holding the camera was healthy and not subject to tremors.
I didn't mean camera wobble but plane wobble and the perspective would change as the plane moved past but I agree that would depend on how far away the plane was.
It might just be me seeing something that isn't there but I could easily believe that someone had obtained a still image of a plane at that angle and then just added it to a video of the buildings.
Here are some planes landing you can just see them wobble if you look closely - and they are trained pilots trying to keep the plan level for landing.
There is not much to see. If you are thinking the planes in the video you shared were "wobbling" you are a very picky pilot. But that is happening in a completely different flight condition where the flaps are deployed, speeds are slow, the pilot is trying to maintain a fixed bank angle (zero!), and the airplane is in ground effect, which tends to amplify wing-induced roll effects. The 9/11 airplane was at high speed, no flaps, and was in a freehand banked turn (no wobble due to pilot corrections). Those conditions tend to produce smooth dynamics.

Yes, you could well be right. I might be trying to invent things in my mind that should not exist anyway.
