No Wake Vortex
All fixed wing aircraft produce an effect called “Wake Vortex”. [#_ftn20 ] Wake vortex is directly related to the amount of lift generated by each wing. The extremely high air pressure from under the wing collides with extremely low pressure from above the wing to create a strong, tornado-like rotating air mass. This is a stable phenomenon, and it can persist for over a minute. The presence of wake vortex is the reason why even the busiest airports wait at least 5 minutes between landings on a given runway. Wake vortices are always present behind a flying airplane. They are invisible, of course, unless there are clouds, smoke or debris in the air.
Following are two photos showing wake vortex behind fixed wing aircraft.
The following series of images is from a video of a plane dropping a load of hydrocarbon incendiaries like Napalm. [#_ftn21 ] Notice how the exploding flame is forced to curl around the vortex.
Now consider this image (fig. 54) from the Naudet video, showing the explosion at WTC 1, the North Tower:
This is less than 5 seconds after a Boeing 767 airplane supposedly flew right through this airspace at top speed. Where is the wake vortex?
fig. 55 is an image from the CNN-Hezarkhani "Ghostplane" video, showing the explosion at WTC2, the South Tower:
Again, what happened to the vortex? I invite all to study the 9/11 airplane videos over and over again. There is no evidence of the strong rotating air mass we know would have to be there.
As far as I know, Steve Wright has given the only official explanation for the missing wake vortex. Wright argues that that the fireball acts as a liquid, and will not mix with the air, instead just pushes the air, vortex and all, back out of the way.
This appears to be nonsense. Wright is confusing chemical mixing with force. Both the vortex and the fireball are gasses in motion – the vortex is rotating, the fireball is expanding. When the two interact with each other, each will exert force on the other, irrespective of whether they are inclined to mix together chemically. Oil and water do not mix. But oil floating on the surface of water will begin rotating when it encounters a whirlpool.
We have video evidence of hydrocarbon explosions strongly affected by wake vortex. [#_ftn22 ]
The missing vortex in all the videos is consistent with the compositing hypothesis, and not at all consistent with the real plane hypothesis.
