Footnote: Early First World War pilots in military aircraft soon discovered that appropriate protective flight goggles were a necessity, due to the cold, sun glare and the all too frequent occurrence of oil leaking into the slipstream and covering the pilot. Originally the German military was caught unprepared and no specific protective goggles for pilots were available, which resulted in the pilots utilizing commercially produced or captured enemy protective goggles. Early in the war, the Carl Zeiss optics firm of Jena developed specific protective flight goggles that became the standard pattern for other manufacturers. Further improvements and refinements of assorted protective flight goggles continued in the inter-war years and by the start of the Second World War, there were no fewer then nine types of protective flight goggles available and nine main manufacturers including, Carl Zeiss, Ernst Leitz, Phillip Winter, O.W. Wagner, Nitsche & Günther, Knothe, Cellowaro, Bauer, Uvex and Auer.
