Alto airfield (also known as Advanced Landing Ground 'Alto' and Alto Air Base) was a temporary airfield that formed part of the "USS Corsica" airbase complex on the east coast of Corsica.
It was built in early 1944, and derived its name from the river that runs nearby, close to the village of Fovelli.

57th fighter group landed at Alto on 23 March 1944 with their P-47 Thunderbolts.
This almost mythical United States Army Air Force unit consisted of three squadrons:
- the 64th, nicknamed "Black Scorpion" 
- the 65th "Fignhting cocks "
- the 66th dubbed" Exterminators "

The Group was based in Corsica Alto (Penta di Casinca) from 23 March until 9 September 1944 and was joined by the French squadrons "Dauphiné", "Navarre" and especially "La Fayette" between 8 May to 14 June. The units participated in “Operation Strangle”, the Allied operations, particularly by USAAFs 12th and 15th Air Forces against the German army in Italy.

THUNDERBOLT MOVIE: “Operation Strangle” had been so notoriously successful that the story was filmed by William Wyler, a celebrated film director. Thousands of feet of film were shot and several movies were created. “Operation Strangle” was produced involving all of the participants in the operation and was shown within the Air Force principally. “Thunderbolt” was produced covering the 57th Fighter Group’s part in the operation only. It was distributed to the public in theatres throughout the country shortly after the war. William Wyler and his crew spent several weeks with the Group in Corsica shooting the raw film. Col. Archie Knight was technical advisor for the film “Thunderbolt.” In the film, the action was introduced by Jimmy Stewart and the action was narrated by Lloyd Bridges. All “actors” in the film were members of the 57th
