Don Wilson, younger brother of Stu Wilson, also a hydroplane racer, died in a fiery crash in Acalpulco, Mexico, on June 19, 1966, when Don collided with another hydro driven by Rex Manchester. Hours earlier, in a single crash, Ron Musson died in Washington, D.C.., on the Potomac River, vying for the President’s. Cup. The death of all three on the same day has come to be forever known as Black Sunday.
