Just two points about the claim:
No steel framed building has collapsed due to fire before or since, so it must have been a controlled demolition
First point: the towers did not collapse due to fire. They collapsed due to fire after suffering extrem physical damage.
Second point: no building as tall as the WTC towers has ever been demolished by controlled demolition. The tallest controlled demolition ever was the J.L. Hudson building demolition in Detroit, carried out by the famous Loizeaux family. That building was 439 feet tall. The WTC towers were about 1370 feet tall -- over three times
as tall as the tallest controlled demolition in history.
If "it never happened before" disproved collapse by fire, it also disproves collapse by controlled demolition.
