"Skilling, based in Seattle, is among the world’s top structural engineers. He is responsible for much of Seattle’s downtown skyline and for several of the world’s tallest structures, including the Trade Center.
Concerned because of a case where an airplane hit the Empire State Building, Skilling’s people did an analysis that showed the towers would withstand the impact of a Boeing 707.
“Our analysis indicated the biggest problem would be the fact that all the fuel (from the airplane) would dump into the building. There would be a horrendous fire. A lot of people would be killed,” he said. “The building structure would still be there.”
Although Skilling is not an explosives expert, he says there are people who do know enough about building demolition to bring a structure like the Trade Center down.
“I would imagine that if you took the top expert in that type of work and gave him the assignment of bringing these buildings down with explosives, I would bet that he could do it.”
