High Quality Content by WIKIPEDIA articles! The Heinkel HE 5, produced in Sweden as the Svenska S 5 and nicknamed the "Hansa", was a reconnaissance seaplane built during the 1920s. It was a further development of the HE 1, sharing its same basic configuration as a low-wing, strut-braced monoplane. The HE 5 also built upon Heinkel`s experiences of mixed construction as used on the HE 4, having a fuselage structure of fabric-covered steel tube, and wooden wings largely skinned in alloy. The usual crew carried was just two, pilot and observer seated in tandem, open cockpits; however, some HE 5s also had a third cockpit which could be used to carry a trainee.
