Manager of Construction says WTC towers could withstand multiple impacts?

I guess that is why he isn't paid for his beliefs ! I see nothing about his engineering degree or credentials that make him an expert ! Simply saying no skyscraper has ever collapsed f rom fire in the past is hardly evidence. Jet fuel burns extremely hot, where the other fires fuel by jet fuel? You are comparing apples and oranges. Oh and I am married to an engineer with more than 40 years experience !
