A 28-year-old Frenchman broke the world record Wednesday for standing on a hot-air balloon at altitude. Rémi Ouvrard stood on top of a hot-air balloon for France’s Telethon at an altitude of more than 3,637 meters (11,932 feet) over Chat

The balloon was piloted by Ouvrard’s father, Jean-Daniel Ouvrard, a seasoned pilot. The altitude was not random: It matches the phone number digits of the Telethon campaign, 36-37, an annual event that raises money for research and advocacy related to rare neuromuscular diseases. The hot-air balloon reached a peak altitude of 4,016 meters (13,175 feet).
