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.
Maximum jet fuel burn temperature is 825 Celsius.
Temperature needed to melt structural steel is 1510 Celsius.

Steel weakens to probably about half strength at the temperatures of the fuel fire. But there was also significant structural damage from the massive collision of the jet. With the way WTC tower was constructed, the collision itself could mostly be responsible for causing some of the floors to collapse, collapsing the whole tower like dominoes.
The only conspiracy I see with 9/11 is they probably knew the attack was going to happen, and allowed it to happen to springboard the Iraq war. But didn't realize the terrorist attack would do that much damage.
To believe the government demolished the towers is ridiculous because they didn't need to do that anyway to realize their agenda. No one can dispute the terrorist flew the jets into the towers. That alone without the towers totally collapsing would've gave the gov justification to invade Iraq and Afghanistan.
