The Fiat CR.42 Falco was a single-seat sesquiplane fighter which served primarily in Italy's Regia Aeronautica before and during World War II. The aircraft entered service in smaller numbers with the air forces of Belgium, Sweden and Hungary. The Fiat CR.42 was the last of the Fiat biplane fighters to enter front line service as a fighter, and represented the epitome of the type. One of the Great Aces that gloriously piloted this aircraft was Luigi Gorrini.
