On display at the Museum of Flight. This rare survivor was built by Thöne und Fiala in 1918. Known as the Berg D.I after its designer Julius von Berg, the type entered service with the Luftfahrttruppen late in World War I. The D.I with a pair of synchronized 8mm Schwarzlose MGs was first flown by Fluggeschwader I (FLG I). The distinctive car-type radiator rounded on top can be seen behind the Knoller-Jaray propeller, but cooling was always an issue. The fighter was mainly used as an escort for reconnaissance aircraft. Frank Linke-Crawford, Julius Arigi and other aces flew the Berg Scout.

Designed by Julius Berg and produced by the Austrian branch of the German Aviatik company, the D.I fighter was one of the better Austrian aircraft of WWI, although pilots preferred the Albatros D.III. Some 700 examples were built in 1917 and 1918. The Austro-Daimler engine was prone to overheating. Note the large radiator filler cap - it almost looks like a crafted mascot!

The D.1 was the first Austrian designed fighter to be built and this rare original was produced by Thöne & Viala in Vienna. It is now on display at the Personal Courage wing at the wonderful Museum of Flight.
