Analysis

While thermaling during the sailplane competition, N45BD was slightly higher and to the left of N295SZ. N45BD made a right turn and struck the right inboard wing section of N294SZ with the outboard wing tip of N45BD. The outboard wing tip of N45BD separated and the pilot elected to parachute to safety. The pilot of N295SZ was able to land his sailplane safely.
