Ordianry fire fighting is to put a hole in the roof of the structure, and spray Water in.
Venezuela used tanker helicopters to put out a fire inthe Parque Central toweres, the buildings did not fall.
The NYFD decided to stop fighting the fire at noon, becuase all people had been removed from the building. Also water pressure was being used on Building 5 and 6.
Probably for some other additional reasons, Building 7 was allowed to burn, without attempting to put out the fires.
The official theory in the final NIST report is that the steel beams and connecting steel plates were weakened by the burning of tghe building and Kerosene which burns at somewhere between 1500 to 1800 F. Steel loses about 90% of its strength at about 1400 Degrees.
What is left out of the official reports is that molten steel was found for weeks after 9-11. Thermite Shape Charges are uised to cut steel beams at an angle so the beams will fall away, and not support the building, as in demolition of a building.
Thermite/Thermate burns at about 25,000 F, and molten steel is between 3000 to 4000 F. The rubble of the buildings was hot for weeks after the WTC 1, 2 &7 Collapsed.
Search Thermite and 9-11 for more details.
Pre-9-11 Iraq war planners needed to scare the Americans to get the US Congress to authorize war. So maybe some of the pre-9-11 Iraq war planners decided it would be more spactacular, if in additon to hitting the towers with air planes, that the towers should actually collapse.
So shape charges were added, and the buildings collapsed, spcctaculraly, and firghteningly.
Only a few of the pre-9-11 Iraq war planners planted the thermite charges, but the others soon figured out what some of their partners had done, so they decided to keep it quiet, and cover up evidence of Thermite/Thermate.
The steel beams with the Sulfer content from Thermate were quickly shipped to China and smelted down.
Congress quickly passed a 9-11 victims compensation act, so lawyers with experts would not be looking for more people to blame for 9-11.
The American public is just now figuring out they were snookered into a war in Iraq, and the Americans are too ashamed of themselves, having been fooled, to have an investigation to find out the facts. So the cover-up continues.

Final Cover-up report with no mention of molten metal or sulfer on the cut beams, nor excessive slag, nor the beams falling away from the WTC towers.
