Published to complement an exhibition at the Zeppelin Museum in Friedrichshafen, Germany, Zeppelins Flieger: Das Flugzeug im Zeppelin-Konzern und in seinen Nachfolgebetrieben [Zeppelin's Aviators: Aircraft In The Zeppelin Group And In Its Successor Firms] is a compendium of highly intriguing essays by a variety of authors. Traditionally, the word "Zeppelin" has become a metaphor for large, silver airships and, inevitably, the image of airship LZ 129 Hindenburg as it perishes near its mooring mast in Lakehurst, New Jersey, in May 1937. Somewhat less immediate, perhaps, might be the association of Zeppelin with the airship bombing raids over England during the First World War.

Far more unknown, however, is the fact that Ferdinand Graf von Zeppelin and the Luftschiffbau Zeppelin [Zeppelin Airship Manufacturing] plant were also involved in numerous aircraft-related undertakings, following humble beginnings as early as 1899. Among the most notable were, perhaps, Ferdinand Graf von Zeppelin's role in establishing Claudius Dornier's Dornier Metallbau [Dornier Metal Construction], later to be renamed Dornier Flugzeugwerke [Dornier Aircraft Manufacturing Plant], or Luftschiffbau Zeppelin's license production of aircraft and rocket components during the Second World War. The extent of the subject matter is astonishingly substantial.

In spite of the fact that a truly comprehensive study of all of Luftschiffbau Zeppelin's aviation activities would undoubtedly merit far more than just one book, Zeppelins Flieger is a truly formidable and wide-ranging study. At 320 tightly printed pages, and with 255 often striking images, Zeppelins Flieger is quite literally a heavy tome. The narrative is subdivided into 16 individual essays, which together form a fairly cohesive record of Zeppelin's non-airship ventures. Among the authors are a number of distinguished German aviation history specialists, such as Karl Kössler, Lutz Budrass, Günter Frost, or Hans-Peter Dabrowski. Each essay is completed by a list of explanatory notes and sources. By far the major part of Zeppelins Flieger covers the years up to 1945, with only comparatively few pages addressing events following the Second World War and up to today.

The content of some of the essays is stunning. Jürgen Bleiber's examination of the revolutionary E.4/20 airliner, for example, is riveting, not least due to the photo content. Equally captivating are Günter Frost's look at Dornier's aircraft of the 1920s, or Hans-Peter Dabrowski's descriptions of Zeppelin's affiliation with the Messerschmitt Me 323 and Luftschiffbau Zeppelin's later projects, such as the ZSO 523 transport, the Fliegende Panzerfaust, the Zeppelin Rammer, and the Zeppelin airliner. Further examples are Peter M. Grosz and Michael Schmeelke's Die Riesenflugzeuge des Zeppelin-Konzerns im Ersten Weltkrieg [Giant Aircraft Of The Zeppelin Group In The First World War], Lutz Budrass' look at Rohrbach and Dornier, or Karl Kössler's brief exploration of the evolution of Dornier's Do 17 design.

Among the most noteworthy essays is Christa Tholander's Ausländische Arbeitskräfte in der Zeit des Zweiten Weltkriegs bei den Dornier-Werken 1939–1945 [Foreign Labour At Dornier's Plants During The Second World War 1939-1945]. Tholander's contribution is based on a doctoral thesis, and it is exemplary that this drastic and all too often quietly excluded topic is an integral part Zeppelins Flieger. One of Tholander's most unexpected revelations is that Dornier explored all legal means at its disposal to improve the living conditions of the Ostarbeiter [eastern workers] in its service.

Zeppelins Flieger can be recommended without hesitation. It is a detailed and expertly researched publication with very high production standards. Its appeal may conceivably be limited only by the fact that it has been published in German. Nonetheless, the fact that Peter Schmoll's various German language works on certain aspects of Messerschmitt's aircraft production have been translated and compiled into the English-language Nest Of Eagles (Classic Publications/Ian Allan Publishing Ltd., England, 2010) leaves room for hope that Zeppelins Flieger, too, might one day be granted a competent English translation.

Arado Ar 96







Arado Ar 96 B Luftwaffe standard trainer, photographed in 1945. Aircraft rests on jacks and is finished in typical 70/71/65 scheme. Visible are both the number "yellow 20" and what appears to be the faded code TG+TN. Also visible are a partial yellow fuselage band and a noticeably bright port wing root fairing.

Enlargement of left background (see bottom photo) reveals a burned-out Messerschmitt Bf 109 wreck. The aircraft's spinner, with white spiral, can be seen on the ground, in front of the Ar 96.

Also of note are the two massive and apparently still intact camouflaged hangars in the background. This photo was apparently taken at Salzburg; the exact date currently remains unknown. (German Aviation 1919-1945 collection)

DKW und die Erla Me-Flugzeuge 1926 bis 1945



Karl-Dieter Seifert, Sutton Verlag GmbH, Erfurt, Germany, 2011, ISBN 978-3-86680-852-2. Illustrated, softcover, published in German.

Karl-Dieter Seifert's DKW und die Erla Me-Flugzeuge 1926 bis 1945 [DKW And Erla Me Aircraft 1926 To 1945] is a true gem. A relatively thin book (at 128 pages), it sheds light on an important but thus far somewhat insufficiently covered and therefore largely unknown facet of German aviation history - the inception of the Erla aircraft factory, and that company's difficult path towards becoming one of Germany's most important aircraft manufacturers of the Second World War. It is notable, for example, that Erla built roughly one third of all Messerschmitt Bf 109s produced. Erla's average daily output of Bf 109s in 1944 was 12 aircraft, in spite of massive supply problems and constant bombing of its manufacturing plants.

Erla was established in 1933 as a small joint venture between sports and sailplane designer Franz Xaver Mehr and Jørgen Skafte Rasmussen's DKW car and motor factory. Erla was originally intended to simply produce the small, single-seat Erla Me 5 sports aircraft, designed by Mehr (hence the "Me" designation). With the rise of the Third Reich and the increasing efforts to re-arm Germany in anticipation of a new war, Erla began to be involved in the license production of military aircraft. By the end of the war, Erla was scheduled to produce Focke-Wulf Ta 152 H fighters. Production activities were by then widely dispersed and/or undertaken by disguised manufacturing facilities operating under code names.

By necessity, the focal point of Seifert's DKW und die Erla Me-Flugzeuge 1926 bis 1945 often lies on Mehr's personal biography, as he remained one of the most noteworthy individuals involved with Erla throughout the company's existence. Mehr found it difficult to relinquish his aspirations to improve upon his early sports aeroplane designs in favour of the demands of the German air ministry (RLM). He even financed some of the work on his later designs from his own salary. Still, the realities of Germany's political course meant that these designs remained prototypes and never entered mass production. Unfortunately, much of Mehr's life is still shrouded in mystery.

DKW und die Erla Me-Flugzeuge 1926 bis 1945 mainly investigates the uneasy balance between Mehr's visions and Erla's inexorable conversion from a small aircraft company to a hugely important military aircraft manufacturer, in the timeframe from the company's inception to the outbreak of the war. This includes the complex and often questionable personal and financial machinations employed to force Erla to align with the RLM's intentions. Erla's further destiny during the war and immediately after the cessation of hostilities is only fleetingly covered on a few pages.

Nonetheless, the book is an extremely absorbing read, and the text further benefits from the inclusion of some 70 mainly unpublished photos and facsimile documents. For anyone truly interested in German sports and paramilitary aviation of the 1920s and 1930s, even these photos alone are reason enough to purchase this little book - as evidenced, for example, by its very cover image.

Deutsche Versuchsanstalt für Luftfahrt (DVL), Berlin-Adlershof, 1936, Part 5







Selected images of new facilities of the Deutsche Versuchsanstalt für Luftfahrt (DVL) [German Research Institute for Aviation] in Berlin-Adlershof, originally published in Moderne Bauformen - Monatshefte für Architektur und Raumkunst [Modern Construction Design - Monthly Magazine For Architecture And Interior Art], volume XXXV, issue no. 10, October 1936, Julius Hoffmann Verlag, Stuttgart, Germany.

Top: fractional view of the Versuchsfeld [test area] of the DVL. The partially visible dark structure to the extreme left is the large wind tunnel, a concrete structure built using the Zeiss-Dywidag-System. It had a diameter of between 8.5 and 12 m, and the airstream was created by an eight-blade fan with a diameter of 8.5 m. The oval building left of centre is the Trudelturm [spin tower] vertical wind tunnel, used for spin trials. The structure in the centre is an assembly hall. The cooling towers of the engine test facility can be seen right of centre. The two reinforced concrete towers to the right were designed to supply air and dissipate acoustic noise to and from the engine test rig. This rig could accommodate engines with propellers up to a diameter of 5 m. The interior of the test rig was furnished with concrete armour in order to withstand the disintegration of airscrews during high-rpm tests.

Centre: close-up view of the then highly innovative Trudelturm vertical wind tunnel. This building, too, was constructed from reinforced concrete.

Bottom: workshops and assembly halls, built from steel frame, infilled with clinker brick. The lower windows provided light to the workbenches, the upper windows illuminated the halls.

Der Flughafen Tempelhof in Entwurfszeichnungen und Modellen, 1939-1944



Elke Dittrich, Lukas Verlag, Berlin, Germany, 2005, ISBN 3-936872-52-X. Illustrated, softcover, published in German.

Cover image © by Lukas Verlag, 2005.


There are numerous books dealing with Berlin's now closed Tempelhof airport and its changeful and often uneasy history. The airport's location within the city of Berlin, combined with its very distinctive architecture and the fact that it played an important role in the Third Reich (both as an airfield and aircraft manufacturing centre), have long made it a unique research project for historians and authors.

Built on what originally were military drill grounds then still outside of Berlin, Tempelhof airfield first became operational in 1923. By 1933, it had become a more substantial facility. It was only in the course of the architectural planning for Adolf Hitler's vision for a rebuilt Berlin, however, that Tempelhof airfield was earmarked to be expanded and developed into a massive airport, clearly designed to radiate power and progress. The new Tempelhof airport was to be an integral part of Berlin's projected north-south axis, itself an utterly revealing expression of the megalomania which had infected the ruling political class.

As it happened, the rebuilt Tempelhof airport was among the very few components of the plan for a new Berlin that were actually completed and, perhaps even more astonishingly, survived the war relatively intact. To this day, the airport's city-facing, curved buildings indicate the once intended circular shape of the large open space in front of the facility. As it proved to be impossible to finish the circular plaza before the end of the war, however, the airport buildings now lack context and thus appear somewhat like lone pieces of a long-lost puzzle.

Tempelhof is probably the most extensively documented German airport of the period before 1945, by means of both magazine articles and books. Its history and operations as an airport have been covered, for example, in the lavishly illustrated Tempelhof - Der Flughafen im Herzen Berlins (Helmut Trunz, GeraMond Verlag, Germany, 2008) or in Flughafen Tempelhof - Berlins Tor zur Welt (Frank Schmitz, be.bra verlag GmbH, Germany, 1997), to name but two of many. The truly excellent Flughafen Tempelhof: Chronik des Berliner Werkes der "Weser" Flugzeugbau GmbH, Bremen - Bau der Kriegsflugzeuge Ju 87 Stuka und FW 190, 1939 - 1945 (F.-Herbert Wenz, Stedinger Verlag, Germany, 2000), on the other hand, is an exhaustive look at wartime aircraft production at the site.

Notwithstanding the large number of publications on Tempelhof airport, Elke Dittrich's Der Flughafen Tempelhof in Entwurfszeichnungen und Modellen, 1939-1944 [Tempelhof Airport in Design Drafts And Models, 1939-1944] is a fascinating little booklet. In spite of containing a mere 36 pages, it's crammed full of information, drawings, and photos. Following a brief introduction and a look at the plans for the rebuilding of Berlin, Dittrich chronicles the evolution of the designs for the new airport in the capital of the Third Reich. An abundance of drawings and photos illustrates the text (some of them previously unpublished), further enhanced by beautifully detailed captions.

Dittrich's text is partially based on her earlier extensive research on Tempelhof airport's architect Ernst Sagebiel, and it also investigates the impact of the involvement of the German air ministry (RLM) and the General Building Inspector for the Capital of the Reich, Albert Speer. While highlighting the correlation between the desires for functionality and political representation, she thankfully refrains from delving into the usual stereotypes. Instead, the reader is provided with facts and information.

Elke Dittrich's Der Flughafen Tempelhof in Entwurfszeichnungen und Modellen, 1939-1944 focuses almost exclusively on the planning and design of Tempelhof airport during the Third Reich, leaving the exploration of its subsequent operations and history to works by other authors. As such, however, it is simply magnificent.
