Capitano Guido Masiero (24 August 1895 – 24 November 1942) was a World War I flying ace credited with five confirmed and ten unconfirmed aerial victories.
[1][2] Finally, on 26 December 1917, in two separate fights, Masiero became an ace, sharing both victories with a number of other Allied pilots.
[2] In December 1918, the month after World War I ended, Masiero was assigned to the Experimental Directorate of the Italian Army's air service.
[2] Masiero had built a reputation for both piloting and technical expertise that saw him part of his country's postwar aviation mission to France, as well as participating in the ELTA Aeronautical Exhibition in Amsterdam.
[3] On 16 July 1935, now-Capitano Masiero was recalled from the Italian Air Force reserve to serve in the Second Italo-Abyssinian War in the 20th Stormo.
[2][3] In 1937, Masiero volunteered to serve in Italy's Aviazione Legionaria ("Aviation Legion") in the Spanish Civil War under the nom de guerre "Guido Magoni".
Following this stint of service, which ended on 31 May 1938,[2] Masiero joined Breda as chief test pilot; he also designed two planes that were never built.
[3] After Italy entered World War II in June 1940, Masiero volunteered to fly a Junkers Ju 87 dive bomber in combat, but was refused.
Masiero was killed while flying in heavy fog in a Macchi C.202 fighter on 24 November 1942 when he collided with Francesco Agello over Milan.
