WTC 7 was riged with eplosives , waiting for the third airplane to hit. But the plane crashed before reatching NY.

Just an possible explanation why WTC7 went down in an , what looks like an controled demolision.
They hade to "Pull the building" when the plaine didnt crash. because they could not let the building standing, full with rigged explosives.
They would have been found othervise.
Sorry for the spelling im swedish.
