What do you think blacksmiths do when they make a horseshoe and the like? They heat the steel, making it malleable and then beat into the shape they want. An all day fire at WTC 7 was the blacksmith, weakening the steel frame until it failed. The fire cladding proves it out. Most steel frames are coated with a 2 hour fire rated cladding. It can withstand fire for two hours. The cladding was knocked off by the collision of the plane in WTC 1 & 2, they fell within a hour. At WTC 7, the fire had to burn THROUGH the cladding, it didn't collapse until hours later.
Another proof, the 2nd building hit was hit at a much lower level than the first building. It had much more weight above the damaged area. It fell BEFORE the first building because of this weight.
then tell me how WTC 7 fell at freefall speed
