"9-11 Truthers" say that there is no possible way that fire could cause the support beams in The World Trade Center to weaken, causing the buildings to collapse. On April 29, 2007 in Oakland California, a tanker truck hauling gasoline wrecked and burst into flames. Fortunately, no one was killed, but the resulting fire weakened the support structure of an overpass causing it to collapse. This, according the the truther argument, is impossible.
Of course, jet fuel is not gasoline. Jet fuel is much like diesel, it burns much hotter and slower than gasoline. Also, the Boeing 767 has a capacity of up to 24,000 US gallons of jet fuel. The tanker that crashed in Oakland had 8,600 gallons capacity.
Any truthers (other than Rosie, of course) care to take a stab at this one? Is this enough to make them say, "Hey, maybe planes did take down the WTC", or did the government secretly blow up the overpass to prove the truthers wrong?
