I can’t resist repeating something I’ve said before: WTC 1 and 2 were EXPLICITLY designed to withstand the impact of large passenger airlines. When they were built, the largest planes were a bit smaller than what came later, but the principle was the same: airliner fuselages are by design light, so a “mesh” was made of the outer walls which would shred them so that nothing hard could reach the core supports. And in the videos you can see the planes disintegrate. It is the same principle which causes us to protect our embassies and other facilities from rocket attacks by putting a high tension wire mesh outside, which serves to detonate contact weapons.
The accounts of the collapses of those two buildings are also ridiculous. I focus on Tower 7 simply because it did not have the complicating factor of having something crash into it.
