The Adventures of Young Indiana Jones: Attack of the Hawkmen (2002)

Working with the French Secret Service, Indy joins the legendary Lafayette Escadrille flying unit and embarks on dangerous airborne reconnaissance missions behind enemy lines. A run-in with German Ace Manfred von Richthofen leads to a death-defying dogfight that leaves Indy grounded and hot-in-pursuit of German aircraft designer Anthony Fokker. Undercover in hostile enemy territory, Indy discovers that the Germans possess a remarkable secret weapon that could change the course of the war and he resolves to bring news of it back to the Allies...if he doesn't destroy it first.
