DescriptionThe Bréguet 761/763/765 are a family of 1940s and 1950s French double-deck transport aircraft produced by Bréguet Aviation.
The aircraft were normally called the Deux-Ponts (Double-Decker) but it was not an official name.
Bréguet began design work on the Bréguet 761 double-deck airliner even before the end of the Second World War, in 1944. It was decided that a medium-range airliner with seating for over 100 passengers would be built. The design envisaged using readily available engines with the aim of ease of manufacture and an early first-flight date. The design was known as Project 76-1. The aircraft was destined not to be the first French postwar design to fly, an honour which instead fell to the Sud-Est Languedoc, a civilianised Bloch MB161. The prototype Br.761, F-WASK, first flew at Villacoublay on 15 February 1949.
The 761 featured a cantilever wing set at mid-height on the bulky fuselage. The retractable tricycle landing gear featured dual-wheel main units. The empennage had twin fins and rudders and a vestigial central fin.
The prototype was powered by four 1,580 hp (1,180 kW) SNECMA 14R-24 radial engines. The Bréguets serving with Air France had up to 107 seats and an elevator between the two floors.
The 763 first flew on 20 July 1951 and entered service with Air France during autumn 1952.
The Air France aircraft had accommodation for 59 passengers on the top deck, and 48 on the lower deck, although the aircraft was capable of carrying 135 passengers in a high-density layout. During 1964 Air France transferred six Br.763s to the French Air Force. The air force also acquired the three pre-production Br.761S aircraft and four new Br.765 Sahara freighter aircraft with removable cargo doors.
