ke=1/2mv2. Big difference in kinetic energy going over 500mph (square being exponential not linear) and taxing at 10 mph(?). Plus tons of fuel burning up in a vertical furnace.
Now do Building 7.
I just pointed out the basic fallacy of the point. Planes did hit the World Trade Center at over 500 mph. I could throw a bullet at someone at 30mph and nothing happens. Muzzle velocity of a 9mm standard bullet at 1,150 fps is a different story.
They were not doing 500MPH but I understand kinetic energy and I am saying thos outer beams would have shreded that thing. And the inner core was yet to come and it's much stronger. I don't think it could have caused the progressive collapse. That's never happened before without explosive cutting charges. But if you look at the debris you'll find lots of beams with explosive cutting charge shapes on the ends.
