Having completed his military service in the Royal Italian Army in the early 1900s, he left Italy for Paris at a very young age.

In May 1912, he returned to Italy and moved to the Aeronautical Service within the then dependent on the Arma del Genio, attending the Caproni School in Somma Lombardo where he obtained his pilot's license.

[3] In October 1912 at Vizzola Ticino, while testing a Caproni apparatus, he was involved in an accident in which he injured his head while the chief engineer of the school, Francesco Piccoli, fell victim.

The squadrons of Aiello were very active during the Tenth Battle of the Isonzo and Captain Gordesco was commended by the Duke of Aosta, commander of the 3rd Army on June 13, 1917, as he said: Commander of the Aiello field, during the offensive of May 1917, his admirable sense of duty was able with such exquisite and personal example, to instill in his employees, so that the two hunting squadrons were fulfilled with fervent enthusiasm and loving constancy a job serious of danger and profitable of precious return.On June 18 at Santa Maria la Longa, the annual Bersaglieri festival took place and Gabriele D'Annunzio was invited to speak.

On August 20, 1917, Gordesco shot down an enemy plane at Komen and it was on the same day that Gabriele D'Annunzio was forced to land three times at the Aiello airfield to repair his bomber.

Beginning in September 1917, the 84th Squadron was also added to Aiello and despite the largely obsolete and inadequate air assets, numerous escort and reconnaissance flights were carried out and many victories were obtained without any losses.

However, after the disastrous Battle of Caporetto, Gordesco was the only commander who served with two squadrons for the entire 3rd Army, day, night and in any weather condition in order to protect the infantry.

He trained numerous pilots from prestigious American universities which were known as the "famous hunters of the air" who later made their mark on the French battlefields of World War I.

The squadron must meet in Calcutta with the SVAs of Lt. Arturo Ferrarin and Guido Masiero who departed from the Centocelle airport on Saturday 14 February at 11.

Once landed, Gordesco impresses even King Constantine I of Greece with his squadron, the celebrations begin but soon he has to leave again for the second stage: he does not fully know the weather conditions, he trusts them even if the organizers are unable to report anything by English stations in Calcutta .

There's more, the Arabs shoot down a plane with his comrades Ferruccio Ranza and Marzari, Gordesco manages to pass but on the border with Persia, in Bushehrdied: it was April 13, 1920.

Arturo Ferrarin, the only driver to complete the Raid Roma Tokio, recalls Mario Gordesco and Giuseppe Grassa : "In Buscir… an engine breakdown… they slammed into a house… both died… The stage officer is gone, and left me here, alone with my pain.I cannot unite in my thoughts the two living figures of Grassa and Gordesco, illuminated by the sun, precise in my memory, with that great sad house of Buscir, without feeling an impression of agony, like a laceration to the brain."

For our part, we give complete and enthusiastic support.In April 1922, the Calabria left from Taranto for Yokohama, its landing department heading to provide assistance to the population of Tokyo hit by an earthquake.
