There are now 1,000 architects and engineers who have signed a petition, saying they doubt the official version of events of 9/11, and calling for a new, independent investigation that considers the possibility of controlled demolitions. When I first discovered their site, in September of 2008, they had 470 A&Es. So it's grown a bit. Their two hour length video can be seen here.
They don't have as many as the 31,000 scientists who have signed a petition doubting man-made global warming. But give them 60 years or so, and they'll catch up.
My excuse for posting this thread is that it is relevant because it is rejected by the mainstream establishment and because it attempts design detection without knowing who the designer is. But if you're not interested in it or object to it, just ignore it and it will be buried in a week or so. And I promise not to post about it again until they get to at least to 1250, unless something spectacularly relevant happens.
