Conspiracy theorists make the claim that photographic and video records of the collapse of the twin towers show debris being projected upward and outward in a manner that can only be explained by explosive ejection. In the 2014 David Hooper film, The Anatomy of a Great Deception (viewable in its entirety at youtube.com/watch?v=l0Q5eZhCPuc ), this subject is covered starting at the 54:16 mark where a brief video clip of high-rise architect Les Young is presented in which he simulates an explosion with his fingers and says:

Then, at the 55:15 mark, David Hooper presents a brief slow-motion video from the collapse of the North Tower and freeze frames it where it appears that a section of debris is shooting upward and outward trailing a streamer of white dust. Hooper tells the audience:
Below is a screen capture from that part of Hooper’s film.

In the frozen frame Hooper presents, it does indeed appear as if the building rubble is being propelled upward leaving an arc of dust in its wake. However, that is merely an illusion resulting from freezing of the frame at an opportune moment. In reality, heavy building rubble only moved outward and downward as it leaned away and broke off from the tower. As the building collapsed, it created a low-pressure zone that sucked dust streamers down with it making it appear, especially in still photos, as if the dust trails from falling rubble were describing an upward arc. Oddly enough, Hooper himself presents video of the collapse at the 54:01 mark that clearly shows the dust trails being sucked down into the collapsing building exposing the lie he tells about them at the 55:15 mark. Below is a clip from Hooper's film between 54:01 and 54:04.
Certainly, seekers of a scientific understanding of the evidence like David Hooper and his Technical Director, Richard Gage could be expected to avoid panning, scanning and freeze framing of photographic evidence in ways that conceal important features and cause the audience to misunderstand what they are seeing.
Window mullions and things went up and out. That kind of stuff can't happen with just pure air pressure of floors being sandwiched together.

In some of these clips you can see projectiles actually propelled upward forming an arc. If this were a gravitational collapse pieces could not be shot upward, and consider the pieces we see. The small pieces weigh a few pounds and the biggest pieces weigh several tons.
