The simple facts of temperatures:
1535ºC (2795ºF) - melting point of iron
~1510ºC (2750ºF) - melting point of typical structural steel
~825ºC (1517ºF) - maximum temperature of hydrocarbon fires burning in the atmosphere without pressurization or pre-heating (premixed fuel and air - blue flame)
Diffuse flames burn far cooler.
Oxygen-starved diffuse flames are cooler yet.
The fires in the towers were diffuse, well below 800ºC. Their dark smoke showed they were oxygen-starved, particularly in the South Tower.
Again, visual input does not cut it, you need to investigate the science behind it.

since you don't seem to have a brain, much less an original thought... i feel that in all fairness, i should at caution you against cutting and pasting arguments from sites that are debunking the very arguments you seem to think you are making.
