Trump's opinion expressed on 9/11/2001 is NOT one of those kinds of truther theory.
Doesn't make Trump's theory correct, but as far as I am concerned, it is not a 9/11 truther theory.
I accept that, but in this case what we think is irrelevant. So why risk the thread over:He's not qualified, engineering-wise, to assert the conclusions he does,?
My late husband, an architect, believed that the buildings failed because code changes were granted to allow the “open floor plan”. The structure of the builing was very different than existing high rises.
Also, there were changes granted regarding the type of fire-retardant material protecting the steel on the exterior of the building. Steel loses it’s tensile strength when heated. Most people who live in the rust belt remember seeing melted steel when watching the steel factory at night.
So insulation failure, steel loss of strength, pancaking floors, accumulating load hitting floors below - an engineering failure to plan for big planes full of fuel hitting the building and exploding.
Another theory to consider - I wonder how the citizens would react if the above were the actual cause. How many lawsuits would be filed? How many millions/billions would be paid out? How many government people who got paid off to change the building codes would go to jail?
Just stuff to consider.
