Science: The energetic materials research and testing center (emrtc) designed explosives to test the effects of burning jet fuel on steel. Emrtc used a bare steel beam because the national institute of standards and technology reports that much of the any fireproofing material would have been knocked off at the moment of impact. Within two minutes of igniting the fuel, the temperature peaked just above 2,000 fahrenheit and complete structural failure occurred in less than four minutes.
