 The impact tore down the fence and snapped off the nose of Walther's car, exposing the driver's legs and breaking open the fuel tanks, which at that time were located beside the driver.The fuel immediately began spraying out of the car, some of it reaching the front rows of the grandstand where several spectators suffered burns.The car crashed back onto the track and spun down the main straightaway upside-down, still spraying fuel which ignited into a huge fireball that enveloped the rest of the field.
