The Avio Linee Italiane (Italian Airlines) Fiat G212CP carrying the team flew into a thunderstorm on the approach to Turin and encountered conditions of low cloud and poor visibility. They were forced to descend to be able to fly visually. While descending for Turin, the aircraft crashed against the base of the rear wall of the Basilica complex at the top of the hill of Superga.
