Source measurement	During the Rhodesian Bush War , the Reims-Cessna FTB 337G 'Lynx' was the main light attack aircraft used by Rhodesian Security Forces during Fire Force counterinsurgency air assault missions, which began in 1974. The Lynxes were armed with twin Browning .303 machine guns mounted above the wing and 37mm SNEB rockets, locally made Mini "Alpha" Bombs ( cluster bombs ), Mini "Golf" Bombs (450 lb (200 kg) blast and shrapnel bomb) and Frantan (a napalm variant carried in frangible drop tanks) bombs.^[source]Cessna Skymaster · Operational history; only the objects and conditions stated in this passage From 1991 until 2001 the Cuban exile group Hermanos al Rescate (Brothers to the Rescue) used Skymasters, among other aircraft, to fly search and rescue missions over the Florida Straits looking for rafters attempting to cross the straits to defect from Cuba, and when they found them, dropped life-saving supplies to them. Rescues were coordinated with the US Coast Guard , which worked closely with the group. They chose Skymasters because their high wing offered better visibility of the waters below, they were reliable and easy to fly for long-duration missions (averaging 7 hours), and they added a margin of safety with twin-engine centerline thrust. In 1996, two of the Brothers to the Rescue Skymasters were shot down by the Cuban Air Force over international waters. Both aircraft were downed by a MiG-29 , while a second jet fighter, a MiG-23 , orbited nearby.^[source]Cessna Skymaster · Operational history / Brothers to the Rescue; only the objects and conditions stated in this passage Original variant first flown in 1961 and introduced for the 1963 and 1964 model years. The 336 had a six-seat cabin and was powered by two 195 hp (145 kW) Continental IO-360-A engines. Production aircraft differed from the prototypes in that they had a roomier cabin and a redesigned rear engine cowling to improve engine cooling and reduce cabin noise. Gross weight was 3,900 lb (1,800 kg).

Among those companies that took interest in the government request was French aircraft manufacturer Dassault Aviation . In December 1961, French aircraft designer and head of Dassault Aviation, Marcel Dassault , gave the go-ahead to proceed with work towards the production of an eight- to 10-seat executive jet /military liaison aircraft, which was initially named as the Dassault-Breguet Mystère 20 . The emerging design was of a low-wing monoplane, which drew upon the aerodynamics of the transonic Dassault Mystère IV fighter-bomber , and was equipped with a pair of rear-mounted 14.68 kN (3,300 lbf) Pratt & Whitney JT12A-8 turbojet engines.^[source]Dassault Falcon 20 · Development / Origins; only the objects and conditions stated in this passage Progress between Dassault and Pan Am was rapid, moving from engineering evaluations of the type to the formation of general agreements between the two companies. In response to feedback received from Pan American, the aircraft was re-engined with a pair of General Electric CF700 engines and several dimensions were increased. Accordingly, Pan American formed an agreement with Dassault to distribute the Mystère 20 in the western hemisphere; the firm placed an initial order for 40 aircraft along with options for a further 120. On 10 July 1964, the re-engined aircraft made its first flight. On 1 January 1965, the first production aircraft performed its maiden flight; in June 1965, both French and American type certifications were awarded. On 10 June 1965, French aviator Jacqueline Auriol achieved the women's world speed record using the first Mystère 20 prototype, having flown at an average recorded speed of 859 km/h over a distance of 1000 km.^[source]Dassault Falcon 20 · Development / Origins; only the objects and conditions stated in this passage In 1973, FedEx's Falcons, designation FA-20-DC, cost $1.2 million each and were modified with a 55-by-74.5-inch forward cargo door with independent power supply, higher mtow, reinforced floor, plugged windows, and bigger brakes.^[source]

During the 1950s and 1960s, the French government, which had taken a significant interest in the re-establishment and growth of its national aviation industries in the aftermath of the Second World War , developed a detailed request for a combined liaison / trainer aircraft, to be equipped with twin-turbofan engines. Among those companies that took interest in the government request was French aircraft manufacturer Dassault Aviation . In December 1961, French aircraft designer and head of Dassault Aviation, Marcel Dassault , gave the go-ahead to proceed with work towards the production of an eight- to 10-seat executive jet /military liaison aircraft, which was initially named as the Dassault-Breguet Mystère 20 . The emerging design was of a low-wing monoplane, which drew upon the aerodynamics of the transonic Dassault Mystère IV fighter-bomber , and was equipped with a pair of rear-mounted 14.68 kN (3,300 lbf) Pratt & Whitney JT12A-8 turbojet engines.^[source]Dassault Falcon 20 · Development / Origins; only the objects and conditions stated in this passage

Progress between Dassault and Pan Am was rapid, moving from engineering evaluations of the type to the formation of general agreements between the two companies. In response to feedback received from Pan American, the aircraft was re-engined with a pair of General Electric CF700 engines and several dimensions were increased. Accordingly, Pan American formed an agreement with Dassault to distribute the Mystère 20 in the western hemisphere; the firm placed an initial order for 40 aircraft along with options for a further 120. On 10 July 1964, the re-engined aircraft made its first flight. On 1 January 1965, the first production aircraft performed its maiden flight; in June 1965, both French and American type certifications were awarded. On 10 June 1965, French aviator Jacqueline Auriol achieved the women's world speed record using the first Mystère 20 prototype, having flown at an average recorded speed of 859 km/h over a distance of 1000 km.^[source]Dassault Falcon 20 · Development / Origins; only the objects and conditions stated in this passage

In 1973, FedEx's Falcons, designation FA-20-DC, cost $1.2 million each and were modified with a 55-by-74.5-inch forward cargo door with independent power supply, higher mtow, reinforced floor, plugged windows, and bigger brakes.^[source]
