Analysis

During an automobile tow/launch, the auto experienced a loss of power before the glider reached a safe release altitude. The pilot had steered the glider off of the paved rwy and was unable to return to the rwy. The glider pilot was forced to land in high foliage where substantial damage was sustained to the empennage. The pilot stated that had he remained over the rwy, the possibility of landing in the foliage would have been avoided.
