Dr Morgan Reynolds claims [as do I and others] that the physics represented in the alleged plane crash videos [mostly "2nd strike" videos of alleged UA flight 175 hitting the south tower] are not real world [i.e they defy known laws of physics] - and that therefor those allaged plane crash videos must be fakes.
Here is a famous, primary example ,variously referred to as the "knife through butter " shot ,"The Vulcan Plane/Building Meld", the "Ghost Plane sequence" "The Self- Healing Building shot" etc.- for what Dr Reynolds and myself would say are obvious reasons, specifically:
the video apparently depicts a large airliner [140 odd tons of hollow, aluminum tubing with a plastic nose-cone] completely disappearing inside a 500,000 ton steel and concrete building with no visible slowing down at impact, and without losing any parts [eg wings, tailsection]on the outside on the shock of the initial impact, to the degree that even the wingtips cut completely through many, massive steel girders and steel floor pans and disappear completely inside the building.
[Also, in higher resolution versions, the wall of WTC 2 can be seen to "self heal" [i.e. become whole again ]after a wing has passed through/ into it , hence the " magic, self-healing building" term ] :
Building Moves- Plane Stationary-Further Video Analysis Dr Reynolds May or May Not Have Seen
Below is an analysis [by "teardrop"] of the last few frames of the same video, that Dr Reynolds may or may not be aware of at this time.
Notice that the tail of the plane remains exactly centered in the frame [red line] and that in reality, it is the building that moves towards the plane , and not the plane towards the building as it should be:
