Guest and residents of Lake Martin got a surprise chance last week to see something that most Americans don’t get to witness.

Videos and photos from multiple observers show a Black Hawk helicopter hovering over the body of water for a short time. What happened next, however, was what drew the attention of everyone on the ground.

One by one, soldiers jumped out of the Black Hawk, activated their chutes and landed in the lake. The water jumps were part of a Family Day event conducted by The Warrior Training Center Brigade. Local reports indicate the troops were from the U.S. Army National Guard 20th Special Forces Group (Airborne), headquartered in Birmingham.
