Garlits was running an overdrive B&J 2-speed transmission with some of his own designs. When he hit the throttle it was like a bomb went off. The 2-speed literally blew up and the results were immediate and devastating. The car was cut in half, severing Garlits' right foot at the arch in the process. Pieces went everywhere including the stands. One spectator lost an arm -- and another suffered near fatal injuries.
