Leutnant Rudolf Friedrich Otto Windisch (27 January 1897 – after 27 May 1918) was a World War I fighter ace credited with 22 victories.

Windisch swooped in on the 3rd to pick Cossel up and carry him back to safety.

This feat earned him the Prussian Order of the Crown (4th Class with Swords); the Kaiser himself presented it on 18 October 1916.

[1][2] In November, he would transfer to Kampfgeschwader der Oberste Heeresleitung II to fly recon missions on the Western Front.

[1][4] Even before his feat of espionage derring-do, Windisch had scored his first aerial victory.

[1] Sometime during this period, Windisch wangled flying time in a captured Spad VII.

[1] The fact that he was one of the original pilots of Germany's best fighter, the Fokker D.VII, gave him tactical advantage over his foes.

A bullet through the gas tank forced him to land behind French lines, about 50 meters from his final victim.

[3] The International Red Cross reported Windisch was a prisoner of war on several occasions.
