Many of these theories state that the steel in the towers would need more heat to melt than the fire is able to provide. Journalist Craig McKee states “The melting point for steel is about 2,800F while the maximum temperature that jet fuel can burn at is about 1,800F” (“Molten Metal Under Trade Center…”). The essence of McKee’s point is that the fire alone could not have caused the steel beams melt. According to Deseret News columnist Suzanne Dean “A Brigham Young University physicist said he now believes an incendiary substance called thermite, bolstered by sulfur, was used to generate exceptionally hot fires at the World Trade Center on 9/11, causing the structural steel to fail and the buildings to collapse” (“Physicist says heat substance felled WTC”). Because the fire produced by the airliner was not hot enough to melt the steel, that meant that an alternative substance was used to collapse the towers. The thermite Dean mentions allows for the towers to fall straight down as if it was a planned
