pancake collapse

Educational study of the 'collapses' we saw on 9/11

Was it really collapses we saw on TV september 11 2001?

Was it really because of the planes impact and the following fires that World Trade Center 1, 2 & 7 came to the ground?
Or did they in fact explode from top to bottom?

It all happaned very fast.
The Twin Towers were 417 meters tall - 63,5 x 63,5 meters wide - and were more or less pulverized in approximately 12 seconds.

Critics of the official account claim this is equivalent to free fall speed. That would mean zero(0) restistance from the buildings own steel and concrete structure on the way down. Zero.

But the Twin Towers were supported by a core of 47 massive steel beams and 236 on the outer sides.
Could really this fast and total demolition be possible without some kind of explosives?

Pancake collapse vs. photographic evidence (comparative graphics)

I want to share with you this graphics, it's my work. Maybe some people will find it useful (i.e. for presentation).

$20 bucks

Five minute video comparing WTC 7 fire to other skyscraper fires, and also to controlled demolition. The video is set to The Blue Danube. A vivid example for just about anyone out of the blue who might be questioning 911. It's brief, easy to listen to, and for the coming holidays and the year ahead, it's a great way to send $20 bucks to everyone you know and love.
