If I may ...
Almost a case of rendition. I was walking down the street when a van pulled up and two big fellows out of nowhere pushed me into the darkened interior just as the door opened up. Immediately a black hood was placed over my head. I couldn't see anything, (It's not like in the movies). After a short drive that seemed like an eternity, the van stopped and the door opened. I was pulled out and walked, between those to big fellas, to a room. I was slammed into a chair and tightly secured with heavy duty zip ties. That's all I am allowed to say. They are not nice people. Anyway ...... I'm back.
First off, those towers were built to withstand the very thing that happened, jet fuel and all. Aeroplanes are just one long aluminum alloy tube with the densest items being the engines. Any amount of fuel, that wasn't dispersed into the air or as a fireball, after impact, was quickly consumed. There just wasn't enough time, for the jet fuel to bend, warp, weaken, fatigue, those steel beams to the point of failure. Also, there was nowhere near the damage or fire with building 7. Explain that one. Not political. Not conspiratorial. Just observational. The size of the building is not relevant because it's construction size is relative to the construction of a taller building. That building was fully engulfed for hours. Nearly the entire structure was burning extremely hot for hours. Yet it still stands. Just making comparisons. Relative to size and all.
