At about 19:15 PDT, a Cessna 172N struck trees shortly after attempting takeoff from Lampson Field. The four occupants were not injured. The pilot said he was practicing touch-and-go landings when the engine lost power after liftoff. He put the airplane back onto the runway, but was unable to stop prior to overrunning the runway and entering a vineyard. A witness reported the flaps were down during the rotation and liftoff, but were up when she arrived at the accident site.
