Sean MacCormac, a Red Bull athlete and pioneer of skysurfing, made history on August 21, 2025, by becoming the first person to grind on the suspension cables of the San Francisco-Oakland Bay Bridge. The stunt involved MacCormac jumping from a helicopter at over 5,500 feet with a parachute and a reinforced board, then riding down the bridge’s cables. The feat was the culmination of 18 months of planning and was widely regarded as a death-defying and unprecedented achievement. Despite the stunt’s scale and impact, including the temporary shutdown of the Bay Bridge, there was no advance warning to drivers, prompting questions about who authorized the event and why the public was not informed beforehand. MacCormac is also known for a previous notable trick, a kickflip over a Harlem subway-platform gap, and serves as a Louis Vuitton ambassador.
