That would be Miguel Entrena Klett of the Spanish EJERCITO DEL AIRE Grupo 27 who claimed 1 P-38.
On March 3 1943 a formation of Allied planes was seen straying into Spanish airspace yet again, and Grupo 27's alert plane was scrambled with Teniente Miguel Entrena Klett at the controls. After climbing to 3500 m, he spotted the target aircraft and identified them as eleven Lockheed P-38s. He then positioned for an attack out of the sun (which was to the rear of the formation) and made a diving pass on the trail-end aircraft. Several hits were made with the 20 mm rounds (his MGs were later discovered to be unloaded), and the plane started trailing smoke and was forced down in Algeria.
