context_page_description: The Besson H-5 was a French transport quadruplane flying boat designed by the Marcel Besson company of Boulogne. The only H-5 was damaged and development was abandoned.
context_section_description: The HB.5 (MB-10) originally started development as an open-sea reconnaissance/bombing flying-boat, but it was completed as a 20-seat passenger transport flying-boat. Described as grotesque it had two sets of staggered biplane wings with an unusual X-type bracing and a biplane tail with triple fins and rudders. Powered by four Salmson 9Z radial engines that were located in tandem pairs in line with the third mainplane.  The H-5 had a conventional fuselage on a three-ply mahogany boat hull, which had 24 watertight compartments.
  The H-5 was tested from the St Raphael naval air station in 1922 and proved to be stable with little vibration. After a few test flights the H-5 was accidentally damaged and development was abandoned.
