Union G.I


  In 1912 the Union-Flugzeugwerke G.m.b.H. was founded at Teltow near Berlin by an aircraft designer named Karl Bomhard, who had previously participated in the design of the Lohner arrow-biplanes (Pfeilflieger) in Austria. He was joined by Dr. Josef Sablatnig (in 1913) and Georg Konig. These two engineers constructed the Union arrow-biplanes based on Bomhard's designs, which were then quite the vogue. One of these aircraft won three world-altitude records with passengers for Germany in 1913.
