Aug. 25/13-The privately operated Pioneer II glider (C-GFJW) was being towed at the London Soaring Club 3 nautical miles W of Embro, ON. The glider began to oscillate laterally shortly after takeoff. The glider released from the tow line at approximately 250 feet AGL and began to bank to the left. The bank continued with the glider contacting the ground at a steep nose down attitude. The pilot, the sole occupant, was fatally injured.
