World Trade Center 7

As told: WTC 7 fell almost symmetrically, at or near free-fall speed for part of its descent, hours after the towers, with no aircraft impact — a signature, the claim says, of a planned demolition rather than of fire.

Suspicion grew from the footage itself and was sharpened by the long delay before any official account was published, and by a live BBC broadcast that reported the collapse before it happened — an error traced to a wire report, but a gift to the argument.

Accounts are deliberately not collected here. This entry documents a historical case rather than a circulating remedy.

Investigators attributed the collapse to uncontrolled office fires fed by burning debris and fought with no working water supply, which caused thermal expansion of floor beams, pushed a critical interior column off its seat, and triggered a progressive interior failure that left the facade to fall as a shell. The report explicitly accepted a period of free-fall descent, which the earlier draft had not, and that concession is why the free-fall point is often quoted. The mechanism is unusual, and independent structural engineers have argued about its details ever since; the case for demolition still requires explosives nobody has produced.
