Why did a third building; 7 World Trade Center, a 47th story building implode?
you evidently have absolutely NO concept of respect whatsoever.
take your amateur tinfoil bullshit to some other thread.
this one is to honor the dead and celebrate the survivors ...
WTC collapsed because the towers were built "on the cheap"…the towers should have been built to a shorter height, around 70 stories…
Why did a third building; 7 World Trade Center, a 47th story building implode?
Because, at 47 stories, they didn’t build it tall enough, according to your silly theory.
Seriously, that building burned for six hours after being riddled with flying beams weighing hundreds of tons and assorted other burning debris. These set entire floors on fire.
In addition to the obvious problems going on that prevented the usual fire departments response, there were also 5 tanks of diesel fuel in the building holding as much as 42,000 gallons of fuel for backup generators, such as the mayor’s command center.
BTW, the steel beams in WTC7 (which wasn’t built until 1987) were treated with fireproofing material, and the rooms holding the diesel tanks were further fire-proofed.
"Any structure anywhere in the world, if you put it in these conditions, it will not stand. The buildings are not designed to be a torch."
- Silvian Marcus, structural engineer
Again, huge fires fueled by massive diesel tanks meant for emergency generators led to to the collapse. These tanks were set on fire sometime during the collapses or the plane impacts. The tanks were directly underneath a transfer beam that supported some 40+ stories of structure above it. Much in the same way the building in OKC fell after a key column was blown away, 7 WTC fell after this main transfer beam failed, leading to the collapse of a key major column. When this collapsed, the entire building went. Again, your nominal 2 hours of fireproofing burnt off after 2 hours. Rememeber this building did not collapse until late in the afternoon.
