Never forget that On September 11, 2 Airplanes can bring down 3 skyscrapers in New York, but can’t burn down a computer desk, electric wiring, file cabinets, asphalt roofing shingles, and a book on a wooden stool at the Pentagon; and the airplane wings (140 ft) can’t break the windows flying at 550 miles per hour (1000 km/h)

Many highly flammable materials found at the Pentagon site, from the same planes that melted steel beams and brought down 3 skyscrapers in New York.
