Analysis

During a 'bomb drop' contest at an organized 'fly-in', the pilot was maneuvering at low airspeed so his passenger could drop a water-filled balloon on a target which had been placed on runway 27. The acft suddenly banked to the right and pitched down striking the ground on the right edge of the runway.
