To the demented such as you,
There is not enough jet fuel in an airliner to melt 100 stories of steel. The elevator shafts are reinforced with additional steel and concrete. Unless prearranged burn and collapse points were created, those towers should not have pancaked down. Demolition experts take weeks to set explosives for buildings to implode that cleanly.
Yes the airliners set the upper floors on fires, But those fires were from paper rubble, decorative paneling.
This was a false flag at its finest, a spectacle so everyone would look at the crashes not the collapse with a critical eye. Enough people were trapped and died so as to ignite grief, outrage and anger.
Meanwhile the crime of letting first responders in without protective gear has killed hundreds since and the toxin filled smoke has made thousands sick with cancer.
