This page on the Escadrille 3 mentions Serbian lieutenant Vladislaw Sondermayer, and the photos which depict that pilot seem to be of the same man as the ones in the Serbian Wikipedia page on Tadija Sondermayer (actually, some of the photos are the same). But the Serbian page also says that Tadija had a brother named Vladislaw, and French sources never mention a pilot named Tadija in Escadrille 3, so I would say this is a case of mistaken identity by some sensation-seeking journalist.
