Jonathan Trappe is a sort of super-hero to some children and a crazy man to some adults. We found him inspirational. Trappe is licensed to fly beneath a group of homemade helium-filled balloons. That means his aircraft is one of the most structurally redundant vehicles in the sky. But it's also challenging to fly. Trappe controls his direction by varying his altitude. He can drop water ballast or stab balloons with a knife to alter his buoyancy as he flies. Wind direction can vary with altitude, and Trappe uses that to his advantage, adjusting his present reality to the forecast conditions. To stay visible to controllers and aircraft, Trappe carries a radio and transponder, making him visible on radar. For visual avoidance, Trappe relies mainly on the 50-foot brightly colored canopy of balloons above his head. At night, he uses lights.
