🧵WTC collapse simplified. The reason the Twin Towers were the "first-ever steel structures to collapse like they did"…
Summary
This thread explains the collapse of the Twin Towers on 9/11 using structural engineering: the buildings' unique design used floor trusses connected to outer walls and inner core columns. When fires heated these trusses, they sagged and snapped, causing a progressive collapse of floors. The thread addresses conspiracy theories by showing that controlled demolition theories lack physical evidence and contradict observed events.
