 Bono later learned that the boat's operator, a sailing instructor, had reached into the water to pick up a tennis ball used for teaching when one of the student's sailboats tipped over and that mast hit the motorboat's throttle, sending the instructor overboard and the boat into a spiral. 17-year-old Brady Procon hopped on the back of his neighbor's personal watercraft. They pulled alongside the runaway boat, and Procon jumped onto it and cut the engine. Bono said in an interview Monday that Brady was a hero.
