What did & did not Cause Collapse of WTC-Journal of Engineering Mechanics

How did this suddenly go down to Older Hot Topics when it was in the Top Five last night?

If you can build a physical model that satisfies your criteria and arrests I would be most interested in seeing a video of its arrested collapse.

Me too! I have, on the Internet, offered Euro 10 000:- to anybody that can produce a structure of any kind, top C of which can destroy bottom A of same structure only due to gravity forces and a drop of C on A.

Details at heiwaco.tripod.com... .

So far only failures have been proposed, i.e. bottom A always arrests top C. Plenty of examples of that are available.

Only excemptions are WTC 1 and 2! Mysterious people suggest that THEY dropped top C of WTC 1 and 2 on bottom A of WTC 1 and 2 and that C crushed A. I have informed FBI about these terrorists but FBI seems to be sleeping at the switches. No response.
