This could be interesting ................
What we saw on TV did happen. The first impact was only recorded on one camera. The second was covered by dozens. The aircraft were there and they hit the buildings ..... the rest comes down to putting the facts together and comparing it with what we saw on TV.
As for the other incidents on the same day, there are no pictures available, so it is all speculation. However WTC7 was filmed and it managed to collapse in exactly (
well almost) the same way as WTC1 and WTC2 ..... and yet it was not hit by an aeroplane.
In the previous posts in this thread there are a lot of misconceptions that are in complete conflict with engineering evidence and Newton’s accepted Laws of gravity and motion. When what we saw defies Universal laws then someone is not telling the truth and somehow I don’t think it was Newton!!!!!
Lets stick to known and provable fact? This is a comprehensive engineering site. It is background facts and are all substantiated with irrefutable engineering evidence and according to design drawings of both towers. It makes no accusations but questions what happened and asks for explanation. Not something that could be called a conspiracy theory ..... just a route to the full facts of what happened ..... not who was behind it.
http://911research.wtc7.net/wtc/evidence/blueprints.htmlThe way each floor was constructed is shown in these original drawings and there was no reinforced concrete floors! It was light concrete poured onto a light corrugated metal deck. I believe there were only three floors that had reinforced concrete and they were the three floors containing the buildings machinery.

The columns ranged from 54” x 22” from the base up to the 66th floor. These were fabricated from 4” thick steel plate. Above that level they gradually reduced in dimension and were made from 2“ steel plate.

They were a relatively light weight light steel matrix pre-fabricated sections that spread the load and supported primarily the weight of the outer skin above. This was in effect a steel box section tube held to the centre columns by the lattice floor beams. Most of the structural weight was taken through the centre core columns.

23,000 US gallons of Jet A1). The largest passenger jet aircraft made at the time of building design, but very little difference between the 707 and the 767.
