 The ratio of results to men and machines lost was positive, but also confirmed the "Regia Aeronautica"s commanders in their mistaken belief that biplanes and triplanes were still valid in modern combat.In fact the age of air warfare dominated by these aircraft was waning and it was becoming evident that radio needed to be mounted on all aircraft and that bomb-aiming needed to be done with special instruments rather than by sight These errors of judgement would prove decisive when Italy entered the Second World War in 1940.Twelve Fiat CR.32 biplanes arrived in Melilla aboard transport ships on 14 August 1936 (405 would be sent to Franco by the end of the operation), and by the end of August the "Cucaracha" squadron was formed at Cáceres with aircraft of that type.
