The Latécoère 521, "Lieutenant de Vaisseau Paris", was a French six-engined flying boat, and one of the first large trans-Atlantic passenger aircraft. The four inboard engines were mounted as tandem push-pull pairs. ==Operational history== The inaugural flight took place on 10 January 1935, followed by a demonstration flight in December 1935 via Dakar, North Africa to Natal, Brazil, then north to the French West Indies. The inaugural flight was to mark the 300th year of French rule in the Americas. Having reached Pensacola, Florida, it was caught in a hurricane and wrecked.〔("Six Motors Drive Big Sea Plane Over Ocean" ''Popular Mechanics'', April 1936 )〕 The aircraft was returned to France by ship to be rebuilt for service with Air France on the trans-Atlantic route. In June 1937 it flew non-stop to Natal before returning to France via the North Atlantic. On 30 December 1937 it set an FAI record carrying a payload of 18040 kg (39,770 lbs) to 2000 meters (6,562 ft) altitude at Biscarrosse, France. (The FAI Bulletin says it had six 650-hp (485-kW) engines at the time.) In 1939 the XB-15 set a new landplane payload record: 14135 kg. Equipped with more powerful engines, the aircraft made four further return flights to New York between May and July 1939. During one of these, pilot Henri Guillaumet flew from New York City to Biscarrosse at an average of 206 km/h (127 mph), including with one engine out. The aircraft could transport 72 passengers in a great comfort. On the lower level there was a salon with 20 armchairs and tables, six deluxe double cabins, each with its own bathroom, seating for a further 22 passengers, a kitchen, a bar and a baggage hold. The upper level had seating for 18 passengers, a storage compartment and an office for the three flight engineers. On the outbreak of World War II the Laté 521 was attached to the French Navy E.6 flotilla, based in Port-Lyautey, Morocco, and was used to patrol the North Atlantic. After the armistice in June 1940 it flew to Berre, near Marseilles, where it was finally wrecked by the retreating Germans in August 1944. The Laté 521 was the basis of the single Laté 522 "Ville de Saint Pierre" civil airliner, and the three Laté 523 navalized variants. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Latécoère 521」の詳細全文を読む スポンサード リンク
