EXCERPTS:
The Ludendorff Bridge (sometimes referred to as the Bridge at Remagen) was a bridge across the river Rhine in Germany which was captured by United States Army forces in early March 1945.
Midway through Operation Lumberjack, on 7 March 1945, the troops of the 1st U.S. Army approached Remagen and were surprised to find that the bridge was still standing.
After the U.S. forces captured the bridge, German forces tried to destroy it many times.
It finally collapsed on 17 March 1945, 10 days after it was captured.

Many structural factors involved. Eventually, weaknesses add up. The foundation shifts just enough, and just like that, a series of things happen.

Dude. it’s a steel frame building. A couple of small fires does not cause them to implode like that in seconds.
It’s literally insane to posture that. You must take a central column from top to bottom at once in order for a building to fall on its own footprint.
