Rofl and this shows clearly why you shouldn't listen to people including those structural engineers. Just because you have some scientific background, does not make you an expert. It doesn't even mean you would understand the field.hwo many of those structural engineers have worked on a structure like the world trade centre? There expertise is in vastly different construction methods. That's where they are pulling their experience from. Unfortunately it doesn't stand up. Their experience in no way relates to the construction used in WTC.
And yes if it happened to buildings constructed in other ways, they wouldn't of fell like that.
A GP has a wide arcing knowledge base they use to diagnose you with, so why is a professional engineer any different?
