A peek into a hangar of the imperial and royal Austro-Hungarian army at its Wiener Strasse aerodrome, now Wiener Neustadt - Ost. The Lohner C.I was an armed version of the Lohner B.VII reconnaissance type. It was rejected for frontline use and issued to training units. Photograph part of a series that must have been taken in 1917 or 1918, not in 1915 as indicated by the source. Photo from: Fortepan
