Comment:
As a person involved in steel structures for over 40 years, I have posted here before that what happened could not have happened just as a result of those planes.
With Architects and Engineers now involved, maybe someone with qualifications (academics as opposed to experienced layman) will ask the right questions.
Good Luck to all!
