Terrifying History on Instagram: "John Vincent did a crazy jump off the World Trade Center in 1991, which was pretty wild but also stirred up a lot of trouble. He was new to this kind of jumping, used gear he didn’t fully understand, and did it all during busy evening traffic. It got him on TV, but not everyone in the jumping community was happy about it. They worried it might ruin things for everyone else. His stunt shows how risky and controversial this adrenaline rush can be."
