’Luftfahrt International’ started off as a thick A5 size magazine of some 160 pages that usually covered three different aircraft types in each issue. These long (40+ pages) detailed articles mainly featured German WW2 types, but also included aircraft from other eras such as WW1. Illustrated with many b+w photos and line drawings, a lot of the information was presented as extracts from the original Luftwaffe handbooks. Rare experimental prototypes and unbuilt projects were also covered in feature articles. Most issues also included at least one non-German aircraft. Other topics covered included aero engines and German aircraft companies. The first issue appeared in January 1974.
From issue 28 this title switched to a more conventional magazine format. It now featured civil aviation news, a spotters feature, airline histories, military aviation news, profiles of historical aircraft types, German aviation history, aircraft museums, book reviews etc.
