Formula One World Championship
(L to R): James Hunt (GBR) with Alan Jones (AUS) Williams, who retired from the race on lap 63 with a damaged skirt. The race was declared a non-championship race due to the FISA-FOCA war and was instead run as a Formula Libre race because the cars did not conform to the 1981 F1 rules prohibiting the use of skirts.
