Hi nom, please provide full details of the evidence which convinced you of such a preposterous scenario.

That would be both time-consuming and pointless, given that you have already illustrated you are not someone to take seriously. All the evidence is available in the public domain, so if you can't be arsed to look for it yourself then I think we can safely conclude you don't want to see it.

But I'll give you a small taste because I'm generous. Here is a fully peer-reviewed study of the chemical composition of the WTC dust, written by Professor Harrit of The University of Copenhagen:-

If you read the paper you will discover the Professor tested five different samples, obtained from five different sources, and got the same results for each sample.

There's also stuff like this:-

A new report accuses the State Department of staggering lapses in its visa program that gave Sept. 11 hijackers entry into the United States.

The political journal National Review obtained the visa applications for 15 of the 19 hijackers — and evidence that all of them should have been denied entry to the country.

I mean, there's literally tons of evidence out there, so I wouldn't bother wasting my time pretending you are interested in looking at it, otherwise you would have done so already.
