Analysis

The glider was being towed for takeoff & had just become airborne when the canopy came open. The plt tried to latch the canopy, but was unable, so he released the glider from the tow plane. While the plt continued to try to latch the canopy, the glider went to the right of the rwy. He then turned back toward the rwy, but the glider was low & its left wing contacted the side of the rwy.
