On this day in 1920, the Luftstreitkräfte, the World War One equivalent of the Luftwaffe, more or less, officially came to an end.

The organization, not surprisingly, had gone through several names and structures before achieving its final one in October 1916. It did not include naval flyers, who remained in the navy, and its association with the German army was organizational such that it was part of the army. It oddly did not include every German army pilot, however, as Bavaria retained an element of organizational control over men recruited from its territory, including at least theoretically its own air force.
After the German surrender it basically came to an end and its one and only commander, Ernst von Hoeppner, left his appointed position as its chief in January 1919 as part of the dissolution of the force in accordance with the Treaty of Versailles which prohibited the Germans from having military aircraft. After that point it existed on paper until this day in 1920.

The German government did field aircraft as late as 1920 when it put down the Ruhr Rebellion, but those aircraft and their pilots were at least theoretically in the Freikorps.
On the German air arm and symbols, an interesting thing to note is how the stylized cross borrowed from the Teutonic Knights has evolved in the German air arm. From 1914 to 1915, it was the full cross pattée associated somewhat inaccurately with the Medieval crusading order that was painted on the sides and wings of German aircraft. In reality, the Teutonic Knights only occasionally employed this style of cross, but it was heavil adopted by the German crown after unification of the country during the Franco Prussian War.
German cross pattée originally used on German aircraft.
In 1915, the cross pattée was slimmed down a bit for some reason.
Cross pattée used from 1915 until March 1918.
In March 1918, it was made a simple straight cross.

The revived Luftwaffe continued to use the simple cross throughout its existence from 1935 until 1945, in a modified form that added emphasis to the lines, but when the post war Luftwaffe was recreated, it went back, with the rest of the German military, to the cross pattée.
