THIS BOOK EXAMINES KEY ENCOUNTERS BETWEEN THE GLOSTER GLADIATOR AND THE FIAT CR.42 FALCO, THE LAST BIPLANE FIGHTERS TO ENTER FRONT-LINE SERVICE, OVER SOME OF THE LESSER-KNOWN THEATRES OF CONFLICT IN WORLD WAR II. Both the Gloster Gladiator and the Fiat CR.42 Falco represented the peak in the development of the biplane fighter, which could trace its lineage back to World War I. However, by the time both aircraft entered service in the late 1930s, they were already obsolete. Nevertheless, they gave sterling service on all fronts in the Mediterranean and Africa in 1940–41. Indeed, the CR.42 was the Regia Aeronautica's staple fighter in both North and East Africa, Greece and over Malta in 1940–41, during which time its pilots routinely fought British and Commonwealth squadrons equipped in the main with Gladiator biplanes. This book explores the bitter dogfights that were fought between these two types as the Allies attempted to gain control of the skies over North Africa, Greece and East Africa. Both types were flown in the main by highly experienced pre-war pilots, and this in turn made for some closely fought engagements, explored here alongside illustrations throughout.
