Just for my own amusement, I called the Las Vegas FAA Flight Standards District Office to see what classification was used for Yves Rossy, who flew down the Grand Canyon for eight minutes with a wing strapped to his back, and four model-airplane jet engines attached to the wing. The FSDO said Rossy was classified as a light jet weighing less than 12,500 pounds, for want of a better guess. Rossy left open the possibility that he might fly somewhere else in the United States, so if you see a guy with a wing on his back, stick around. That means he is going to do it again. Can you see Jetman looping the Golden Gate Bridge? I can.
