The NTSB's narrative final · quoted from the NTSB record

THE PRIVATE GLIDER PILOT WAS ATTEMPTING AN AEROTOW TAKEOFF UTILIZING A CESSNA 150 AS A TOW PLANE. DURING THE TAKEOFF, THE TOW PLANE ABORTED THE TAKEOFF. WHEN THE GLIDER PILOT REALIZED THAT THE TOW PLANE HAD ABORTED THE TAKEOFF, HE WAS ALREADY AIRBORNE AND DID NOT HAVE SUFFICIENT RUNWAY LEFT TO LAND. WHILE MANEUVERING THE AIRCRAFT FOR AN EMERGENCY LANDING, THE AIRCRAFT STALLED AND COLLIDED WITH THE TERRAIN. SUBSEQUENT INVESGIATION REVEALED NO MECHANIC MALFUNCTIONS WITH EITHER THE GLIDER OR THE TOW PLANE.
