Preserved at the Technisches Museum Wien (Vienna Technical Museum) is the only original World War I fighter plane of Austrian design and manufacture.

Demilitarisation and its handover to the Technisches Museum after World War I allowed the fighter plane to be preserved. The far-reaching arms limitations contained in the Peace Treaty of St. Germain were such that this fighter aircraft was also rendered non-operational. For the presentation in the aviation exhibition newly opened at the Technisches Museum Wien in 1927 the wing covering on the starboard side and the plywood fairing of the fuselage were removed; the engine was cut open. The two lower airfoils were also sawn off so the exhibit could be set up on the 1st floor gallery.

The 101 series built by Thöne & Fiala was originally fitted with a 200 hp Austro-Daimler engine. This was in contrast with the 160 hp version, which was powered by an electric motor for demonstration purposes. It was only for the Museum’s 1999 refurbishment that the biplane was restored as far as possible to its original state. The unstable fuselage structure was also complemented and reinforced.

The biplane was the first fighter plane to be built in Austria-Hungary and manufactured in series.
In early 1916 the engineer Julius Berg, who was working for the aircraft factory Aviatik Ges.m.b.H. in Wien-Heiligenstadt, designed a two-seater reconnaissance/fighter aircraft type and a single-seater fighter plane, the D I. The first series aircraft were produced in May 1917. These new fighter planes had an exceptional climb rate and reached a top speed of 197 km/h. More and more fighter planes were needed during those months of the war, and so other aircraft companies were commissioned to manufacture the aircraft under licence, among them Thöne & Fiala and the Wiener Karosserie Fabrik [Vienna (Car) Body Factory].
