Here’s some video I took of large ice falling off a 1,500 ft. TV tower I live next to. This happens every few years after a snowstorm, and is mostly due to supercooled cloud water freezing to the tower and support cables (we didn’t have an ice storm…but did have 6 inches of snow). The falling ice sounds a little like a propeller plane coming in to land.
Best watched full-screen, with HD enabled, turn up your sound, and don’t miss the ending.
