Unknown birds over German lands
by Günter Frost (ADL)
During the decades in which the ADL was concerned with researching German aviation history, a whole series of photographs accumulated that could not previously be assigned to any aircraft type. The machines that were photographed were (almost) exclusively one-offs that were either self-made or came from a smaller manufacturing company. Even if they were mostly not about pioneering inventions or technical innovations, these UFOs - "unknown flight objects" - belong to the history of German aviation technology and should be saved from being forgotten.
In this article, a selection of photos of previously unidentified aircraft types from the 1920s and 1930s is presented in order to make the images available to as large a group of aviation enthusiasts as possible. Of course, we combine this with the hope that one or the other reader may be able to provide useful information on individual photos. This includes not only direct information about the respective aircraft type and its builder, but also background information such as information on the place or time of the photo in question and, if necessary, also about people who are photographed in the pictures.
In the interest of aviation history documentation, we ask for relevant information to us, the easiest way to do this by email. In contrast to print media, new findings can be taken into account on the Internet at any time and published promptly. We will report on the results in any case.
Since no meaningful sorting was possible due to a lack of information, the order of the following photos was more or less a coincidence.
