At 16:00 EDT, a propeller blade on a homebuilt Velocity RG separated during a high-speed low pass over the runway at Cobb County-McCollum Field. The pilot and his passenger received minor injuries. The pilot reported that he was making a low pass over the runway at 245 mph when he felt a vibration in the airframe. He began climbing but within seconds the engine lost power. The pilot selected a forced landing area where the airplane struck trees and a chain link fence. Debris from the airplane was recovered from the approach end of the runway.
