Aldo Ligabò was from Castel D'Ario (Mantova).

Ligabò took part in the Spanish Civil War where he served in the 1^a Escuadrilla de Caza del Tercio.

In the morning on 30 October, Sottotenente Adriano Mantelli of the 1^a Escuadrilla de Caza del Tercio and his flight consisting of Sergente Ligabò and Sergente Adamo Giuglietti, intercepted a formation of three Potez 540 bombers over Navalcarnero. Leading the Republican bomber formation was the second- in-command of the Escuadra Internacional (Escuadra N^o 4), Spaniard comandante Sampil, while the remaining two aircraft were flown by Bulgarian Zakharij Zakharev (’Volkan Goranov’) and Russian Ivan Proskurov. Zakharev’s (Potez 540 ‘N’) crew included three Spaniards (co-pilot, flight mechanic and a gunner), Petr Pavlovich Desnitskiy (lower turret gunner), Anatoli Ivanov (gunner) and leitenant Kuz’ma Demenchuk (navigator).
The Republican bombers were surprised and initially blinded by the sun when the CR.32s initially targeted Zakharev’s Potez, setting one of its engines on fire. The lower turret gunner Desnitskiy kept firing his gun even after he was hit, claiming an enemy fighter. He was pulled from his position and replaced by leitenant Demenchuk, who also was pulled from the turret just before the bomber crash-landed.
Proskurov attempted to assist his comrade by slowing down and positioning his aircraft between Zakharev and the opposing fighters. This courageous action won him the admiration of the Italian pilots, but it was ultimately performed in vain as the damaged bomber was doomed.
Although wounded in the leg by a bullet, Zakharev tried to nurse his stricken aircraft to the safety of Republican territory, but he and his Spanish co-pilot Pérez Sancho force-landed the aircraft in a clearing in No Man’s Land. All five crew managed to escape the wreckage and reach friendly troops with Zakharev, Desnitskiy and Demenchuck wounded by gunfire from the Italian fighters. A short while later Sottotenente Mantelli shot down Proskurov’s Potez over Republican territory. Like Zakharev, the skilful Russian pilot also managed to save the lives of his crew by carrying out a successful emergency landing in a vineyard near Getafe. Although Mantelli also was credited with the destruction of flight leader Sampil’s Potez, the latter had in fact made it back to base at Albacete.
Mantelli, like his wingmen, returned to Talavera to find that his CR.32 had been holed in several places by fire from Proskurov’s gunner, Vladimirov, who had continued to fire at the Italian fighter in spite of a serious wound to one of his hands.
The Potez 540 flown by Zakharev was flown from Toulouse to Barcelona on 15 September, before heading on to Madrid to be assigned to the Escuadra Internacional (Escuadra N^o 4).

Ligabò claimed 1 shared biplane victory during the Spanish Civil War.
