Jagdstaffel 28

Royal Württemberg Jagdstaffel 28, commonly abbreviated to Jasta 28, was a "hunting group" (i.e., fighter squadron) of the Luftstreitkräfte, the air arm of the Imperial German Army during World War I. As one of the original German fighter squadrons, the unit would score 100 verified aerial victories. The Jasta would pay a blood price for its success: nine pilots killed in action, three wounded in action, one injured in a collision, and one prisoner of war.

History
Royal Württemberg Jagdstaffel 28 was founded on 14 December 1916 at FEA 10 at Böblingen. Oberleutnant Lang from Jasta 11 was assigned to command it. After Leutnant Lang's reassignment, the squadron would have three commanders killed in combat within four months. Leutnant Emil Thuy then took over, and helmed the squadron throughout war's end.
