THE PRIVATE PILOT WAS TRYING TO SELL HIS AIRPLANE AND ALLOWED THE STUDENT PILOT TO FLY IT FROM THE LEFT SEAT. THE STUDENT PILOT LANDED ON THE RUNWAY BUT LOST CONTROL, DEPARTED THE SIDE OF THE RUNWAY, THEN HIT A VASI LIGHT. THE AIRPLANE STOPPED WHEN IT HIT A STAND OF TREES. THERE WAS A STRONG GUSTY CROSSWIND. THE PRIVATE PILOT/OWNER CLAIMED HE WAS ALONG AS A PASSENGER/OBSERVER.
