Degania Alef
Hoz and Yitzhak Ben Ya'akov from Degania Alef were the founders of Aviron Aviation Company, for which Hoz acted as CEO. Aviron was one of a handful of aviation pioneering enterprises of the Yishuv, created with its foreseeable security needs in mind. It trained pilots and established flight lines in Mandatory Palestine and outside, while serving as cover for the budding, tiny and illegal "air force" of the Yishuv, eventually organised between 1945 and 10 November 1947 as Palmach's Palavir, and then until Independence as the Haganah's Sherut Avir.
