The latest issue of Niagara Life Magazine had an article about some of the people who have gone over the Falls:

For almost a hundred years, men— real men — have come to Niagara Falls to defy the will of Mother Nature, to challenge the raging torrents of the mighty Niagara River, to lay their lives on the line, the line that drops dramatically 170 feet straight down into a churning canyon of angry currents. I tell you, these are men with nerves of steel. These are men with hearts of lions.
