WWII -1940 1941 - North African Campaign - Wonders of Italian aviation in Marmarica. Defying the sandstorm that transforms the atmosphere in hell, thirty our planes swoop in on mass and disrupt enemy columns paralyzing the ground. The 5th Squad airline that has participated in these operations has earned the praise of the Duce, from La Domenica del Corriere del December 29, 1940. The Fiat CR.42 Falco (Falcon) was a single-seat sesquiplane fighter which served primarily in Italy's Regia Aeronautica before and during World War II.
