05/27/2017. Remarks by Kees Kort: "Dr. Josef Sablatnig (1868-1945) set a new world record on September 27, 1912 with three passengers to a height of 1,120 metres. The aircraft was a Pfeil-Doppeldecker (arrow-winged biplane), constructed and built by Ing. Karl Bomhard. By the end of 1912, the two were joined by Georg König and formed the small Union-Flugzeugwerke GmbH in Berlin-Teltow (Germany). Up to 1916 it designed aircraft, but lack of orders led to the takeover of the company by the Norddeutsche Flugzeugwerke.

The unique Union Wasserdoppeldecker (sea biplane) was designed in 1913. The three-bay aircraft with twin floats was powered by a 120 hp Austro-Daimler engine. The machine was bought by the Reichsmarine (German Navy) and got the serial 73, however, assigned to the naval station Kiel it crashed before the start of WW I."
