The Corpo Aereo Italiano, or CAI, was an expeditionary force from the Italian Regia Aeronautica that participated in the Battle of Britain and the Blitz during the final months of 1940 during World War II. The CAI supported the German Air Force (Luftwaffe) and flew against the British Royal Air Force (RAF) and Fleet Air Arm (FAA). The CAI achieved limited success during its brief existence, but it was generally hampered by the inadequacy of its equipment.

The CANT Z.1007 Alcione (Kingfisher) was an Italian three-engined medium bomber, with wooden structure. Designed by Filippo Zappata, who also designed the CANT Z.506 it had "excellent flying characteristics and good stability" and was regarded by some as "the best Italian bomber of World War II" although its wooden structure was easily damaged by the climate, as experienced in North Africa and in Russia. It was used by the Italian Regia Aeronautica, Italian Co-Belligerent Air Force, Aeronautica Nazionale Repubblicana and Luftwaffe during World War II.
