There's just a handful of people who've survived falling, either on purpose of accidentally, over Niagara Falls. In fact, the fourth person ever to survive the fall unprotected, went over the falls just last month.

The combined Niagara Falls form the international border between the Canadian province of Ontario and the New York State and have the highest flow rate of any water fall in the world with a vertical drop of 165 feet.

The video above chronicles a few of the survival stories from those who've gone over the falls. Watch Roger Woodward's story about his childhood trip over the falls after he fell out of his uncle's boat.
