The single column " theory" if ridiculous. There are literally hundreds of columns in a structure like that. It's like saying if a single stud was removed from a wood frame building it would fall down. It's laughable. Believe me, I've demoed wood frame structures ( a garage and a 60 year old UN-permitted guest house). They don't just fall down and the column/beam connections are far more rugged in steel frames than wood.
Uh-huh. And how many 47 story buildings did you design and build in the mid 1960s?
I've never designed any steel framed buildings but I have a basic knowledge of them, enough to know they can't just fall down.
Obviously no buildings just fell down on 9/11 and just claiming that to be the case exposes you as a dishonest player, just like the rest of the loony CTs.
And from your question I can see you can't quite follow a thought. I said I demolished an Un-permitted guest house that was 60years old. The point about it being un- permitted was that it was a sub standard structure and even as such it didn't just fall down, it took a crew of four and a skid steer tractor most of a day to take it down.
Buildings don't just fall down, especially steel frame high rises, the most engineered buildings in history.
There is no comparison between your guest house demo and the collapse of any building on 9/11. Clearly you have inflated delusions of self-importance.
