Since the inception of youtube, I’ve watched hundreds of this tower collapse videos. I don’t know why, it interests me. This video is of the Coast Guard LORAN C tower in Port Clarence, Alaska. For what it’s worth, Port Clarence looks like a forlorn place, I am inclined to think my duty on Guam was rather nice in comparison.
This was filmed from six separate camera locations, including one at the base. It demonstrates how most towers fall within 1/3 of their constructed height. In this demolition, all three guy points are cut at the same time, removing the equalizing forces simultaneously. This would be the same situation as a catastrophic failure of a load-bearing tower member.
The best parts of this video are the camera view of the tower base, around 1:04-1:19, and the side view where the camera almost gets hit by a tower section, 2:02-2:13.
I love physics.
