Horst-Günther von Fassong was a German Luftwaffe military aviator and fighter ace during World War II. Depending on source, he is credited between 63 and 136 aerial victories achieved in an unknown number of combat missions. This figure includes up to 90 aerial victories on the Eastern Front, and potentially further 46 victories over the Western Allies, including up to four four-engined bombers.

Operation Bodenplatte, launched on 1 January 1945, was an attempt by the Luftwaffe to cripple Allied air forces in the Low Countries during the Second World War. The goal of Bodenplatte was to gain air superiority during the stagnant stage of the Battle of the Bulge so that the German Army and Waffen-SS forces could resume their advance. The operation was planned for 16 December 1944, but was delayed repeatedly due to bad weather until New Year's Day, the first day that happened to be suitable. It resulted in almost 500 destroyed Allied airplanes.
