@Flieger Flab Museum, Dubendorf, Switzerland
The Swiss Air Force museum is located in Dubendorf, on the outskirts of Zurich. Definitely recommend this museum to anyone visiting the area. Many unique aircraft like this one. First flown in 1916, the Häfeli DH-1 was a 1910s Swiss two-seat reconnaissance aircraft, built by the aircraft department of the Federal Construction Works (Eidgenoessische Konstruktionswerkstaette, K+W) at Thun, Switzerland. Six examples were produced. Nikon D500 w/Tokina 10-17mm, processed with Aperture.
