>intense structural fires can reach up to 1,800°F to 2,000°F, hot enough to melt glass and soften steel.>Jet fuel burns at 800° to 1500°F, not hot enough to melt steel.>Structural steel melts at around 2,750°F (1,510°C), meaning jet fuel alone does not burn hot enough to melt steel.The steel columns were typically modular units, about 18 inches (47 cm) wide. Steel thickness at a height of 36 feet high, 6 feet wide and 16,000 lbs>Ok it was the impact of the plane that weakened the steel.The nose cone of the plane is made out of fiber glass to allow radio communication and transmitting during flight an inferior material or component will cause enough damage for it to fall downward instead of the frame bending and cracking??
>>542411212What purpose did this camera even serve? Blurry and like 1 frame per second? At the Pentagon of all places Really im to believe an airplane flew that low in Washington dc
