In 1951, Jahanbani was selected to be sent to Fürstenfeldbruck Air Base in Germany to attend the jet pilot training school to become a pilot for the first Iranian jet fighter aircraft, the F-84 Thunderjet, which was scheduled for delivery in 1955, along with 15 other pilots. Upon completion of the training, 10 pilots returned to Iran while Jahanbani, along with four others, continued their training to become instructors upon return to homeland.
