It was an eightieth birthday present to herself that went horribly wrong. Laverne Everett jumped out of an airplane and almost out of her tandem skydiving harness to her death.

Laverne said she had no idea what kind of danger she was in during the jump, only finding out about it when she watched the terrifying video after the fact. And it wasn’t until a year later that Everett’s sister posted the video on YouTube.

Take a look at the video. It almost takes your breath away.
