: "This replica was built by Marcel Sezemský and members of Historická letka Republiky Československé (Historic Flight Czech Republic). Powered by an original 60 hp Walter NZ-60 five-cylinder air-cooled radial engine, it flew for the first time at Mladá Boleslav, Czech Republic, on June 1, 2007. The marking L-BOSA was the registration under which the original BH.5 was registered on June 23, 1923."
