Evidence for Planes at the WTC?

Some anonymous 9/11 "truther" has compiled all the evidence for planes at the WTC.

Here's the deal--

1) beyond any reasonable doubt, photos and videos of the second plane are fake

2) some plane parts, such as the engine under the canopy, were planted

3) the second (south tower) hit was by all indications a giant hoax-- no plane hit the tower-- and witnesses to that either saw it on TV or were fooled in some other way

4) some type of aircraft may have impacted the north tower, and this may account for some of the plane parts that were found

IMPORTANTLY-- NO ONE HAS EVER MATCHED ANY AIRCRAFT PARTS "FOUND" AT THE WTC TO THE PLANES THAT OFFICIALLY CRASHED.

Aircraft parts all have serial numbers. No one has matched the serial numbers of the plane debris to the flight 11 or flight 175 planes. Same for the other 9/11 crashes, for that matter.

Unless there is some very serious accounting of all aircraft parts from all four planes, there is every reason to think the official plane crashes were hoaxes.

What we have NEVER been shown for the plane crashes: one of any of the four tail sections (which usually survive crashes best) and even one of the hundreds of seats that should have been on the planes.
