When I was at school, our physics teacher, Mr Pugh, spent a whole lesson describing his accident flying an L5 out of Imphal. Apparently he was following a telephone line through the jungle and was so intent on his task he didn't notice a cliff in front of him. He crashed into the trees but fortunately was unhurt. Although he was now behind Japanese lines, he did manage to walk home unhindered. Best physics lesson I ever had.
