THE PLT REPORTED THAT BEFORE STARTING HIS TAKEOFF, THE TOW PLANE WAS POSITIONED TO THE LEFT OF THE GLIDER. THE WIND WAS FROM 030 DEG AT 8 KTS. AS THE TAKEOFF COMMENCED, THE GLIDER WAS PULLED TO THE LEFT. THE GLIDER'S LEFT WING STRUCK THE RWY, FOLLOWED BY THE RIGHT WING, THEN THE GLIDER SWERVED TO THE RIGHT.
