Good morning, guys. Excellent additions!
Derived from the Short Calcutta, Breguet Br. 521 Bizerte was a three engined sesquiplane flying boat and the core of the long range MR of the French Aeronavale during the late interwar period. A dozen or so were used by the Luftwaffe as SAR airplanes, mainly based in the Atlantic coast of ocupied France.
As the fighters were more advanced in the mid 1930s, the current combat training was no longer useful and a new type of trainer was needed. Morane Saulnier modified a MS-405 fighter airframe with a Salmson 9 cylinder radial engine, a tandem cockpit por two pilots and an odd looking empenage, creating the MS-430 trainer aircraft.
Unfortunatelly, the aircraft was underpowered, so a new version with a more potent Gnome et Rhone radial and a new empenage was made and almost without further tests, ordered for production in 1939. But in that chaotic year year, the production was severly delayed, and by June (the fall of France) any production aircraft was ready, but the prototype, which was found by the germans in Marignane in 1940 and scuttled.
Cheers.
