Mario Visintini, MOVM, (26 April 1913 – 11 February 1941) was an Italian military pilot, the first Regia Aeronautica flying ace of World War II. In recognition of his flying skill and meticulousness, Visintini was nicknamed cacciatore scientifico (scientific hunter).
Visintini was the top scoring pilot of all belligerent air forces in Eastern Africa (Africa Orientale) and the top biplane fighter ace of World War II; he achieved all his air victories flying the Fiat CR.42 biplane. He is credited with 16 confirmed air victories (20, according to other sources) and five probables, plus two victories achieved during the Spanish Civil War serving in the Aviazione Legionaria.
Early years
Mario Visentin (later changed to "Visintini") was born in Parenzo d'Istria, now Poreč in Croatia, on 26 April 1913. His father was an agricultural expert. Visintini tried to enter the Regia Accademia Aeronautica but did not pass the medical examination because he was declared "too weak and susceptible". So he enrolled in the Faculty of Agricultural Sciences at "Università di Bologna". Subsequently, in spring 1936, he entered the air training centre at Caproni di Taliedo. Transferred to Lecce, Visintini followed the usual training program. He gained his civilian pilot's licence on 30 May 1936 and his military wings in September 1936. Two months later, he qualified as a military pilot at Grottaglie, Taranto, on Breda Ba.25s and Fiat CR.20s. With the rank of Sottotenente, he was posted to the 91ª Squadriglia, 10°Gruppo, 4° Stormo, at Gorizia, in northeast Italy, where he trained on Fiat CR.30s and Fiat CR.32s.
In November 1937, Visintini volunteered for service in the Spanish Civil War. He was attached to 25ªSquadriglia of XVI° Gruppo "La Cucaracha", then equipped with Fiat CR.32s. In Spain, Visintini distinguished himself as an outstanding pilot, claiming a number of kills. At least two of his victories are confirmed. On 24 August 1938 he shot down a Russian Polikarpov I-15 fighter aircraft, while, on 5 September 1938, he claimed a Polikarpov I-16 of 1ª Escuadrilla Chatos, over Venta de los Campesinos. In October 1938, after 330 hours of combat, Visintini returned to Italy, rejoining 4° Stormo. For his service in Spain, he was decorated with a first Medaglia d'Argento al valor militare(Silver Medal for military valour). In September 1939, he was promoted in Servizio Permanente Effettivo.
East Africa
In April 1940, Visintini, was transferred to 412ª Squadriglia. This unit had, in its ranks, a good number of ex-4° Stormo (the Royal Italian Air Force's elite unit) pilots and - after only one year of operations - produced five aces. On 12 June, two days after Italy entered World War II, flying from Gura, he claimed a Vickers Wellesley bomber K7747 of No. 223 Squadron RAF (F/O Ross a Cpl. Stevenson, plane returned but crashed when landing). It was the first of his 16 air victories during the conflict, in Eastern Africa Two days later, on 14 June 1940, he intercepted a pair of Vickers Wellesleys from No. 14 Squadron RAF, en route to bomb Massawa. Visintini shot down aircraft K7743, flown by Pilot Officer Reginald Patrick Blenner Plunkett. Plunkett fell in the Red Sea and was never found despite a search mission undertaken. During a reconnaissance flight over Dekemhare (Italianized as Decamerè), on 3 July 1940 (according to other authors, on 4 July), Visintini shot down another Wellesley (L2652), from No. 14 Squadron, flown by 26-year-old Flying Officer Samuel Gustav Soderholm (RAF No. 40194), who was killed in the crash.
