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

THE GLIDER PILOT HAD FLOWN FOR ABOUT 1.5 HOURS AND WAS HEADING BACK TO THE AIRSTRIP FOR LANDING. HE DID NOT MAINTAIN SUFFICIENT ALTITUDE TO REACH THE AIRSTRIP, SO HE ELECTED TO LAND THE GLIDER IN AN OPEN FIELD. THE LEFT WING COLLIDED WITH A TREE ADJACENT TO THE FIELD, AND THE PILOT LOST CONTROL OF THE GLIDER. THE GLIDER CRASHED ONTO THE FIELD IN A NOSE LOW ATTITUDE. HE REPORTED NO MECHANICAL PROBLEMS WITH THE GLIDER.
