At about 10:05 eastern time, a Cessna 152 struck a standing Beech 35-B33 at Herlong Airport. The commercial-rated pilot in the Cessna and the three occupants of the Bonanza were not injured. The Cessna pilot said he was running the engine on the parking ramp in an attempt to clear some roughness prior to flight. The Bonanza pilot and passengers had boarded, but the engine had not yet been started. The Cessna pilot said his feet slipped off the brakes and the airplane moved forward and struck the Bonanza.
