if you would be so good as to explain the humour of Richard Gage; you must admit, it's a little frightening to think any steel office tower you enter could be brought down by office fires. Should not the entire construction industry have been made to undergo a total re-write if this were true? Oh, and where are the Shanksville/Pentagon planes? How did tons of steel get impaled in neighbouring buildings? I suspect you didn't watch the Wiggington video. Check out Bill Vander Zalm about geoengineering. Has the cost of an architect's professional liability insurance skyrocketed as a result of 9/11? If not, why not? Best regards
