Morane - Saulnier MS . 760 Paris The Morane - Saulnier MS . 760 Paris is a French four ( or six ) seat jet trainer and liaison aircraft built by Morane - Saulnier . Based on the earlier side - by - side seating two - seat trainer , but adding an additional row of two seats , the MS . 755 Fleuret , the Paris was used by the French military between 1959 and 1997 . In 1955 , a short - lived venture with Beech Aircraft to market the Paris as an Executive Business Jet in the US market was soon eclipsed by Learjet ’ s Model 23 . While four seat propeller planes are common , jet - powered planes with this seating arrangement such as the Grumman EA - 6B Prowler are comparatively rare . Design and development . In the early 1950s the French Air Force needed an ab - initio jet trainer ; Morane - Saulnier proposed the MS . 755 Fleuret , but the competition was won by the Fouga Magister . The company re - designed the MS . 755 as a four - seat liaison aircraft which they called the MS . 760 Paris . On 29 July 1954 the prototype MS . 760 , registered F - WGVO ( F - BGVO ) , took off on its maiden flight . With its T - shaped vertical stabilizer , low wing , and two Turbomeca Marboré II 400 kg turbines internally mounted side - by - side in the aft fuselage , the Paris offered a platform characterized by inherent stability . The aircraft had four seats , two in the front and two in the back , and a retractable tricycle landing gear . The French military ordered 50 aircraft for liaison duties , for both the French Air Force ( 36 ) and Navy ( 14 ) . The first production aircraft flew on 27 February 1958 . In 1961 , production plants started rolling out the MS . 760B Paris II , fitted with two Marboré VI 480 kg engines , wingtip fuel tanks , air conditioning , and a bigger luggage compartment . On 24 February 1964 , a six - passenger version , designated MS . 760C Paris III , made its first flight , but there was no production of this variant . Production of the Paris II ceased , and production of the Paris III never started . Some 153 aircraft ( Paris I and Paris II ) were produced for the French Air Force ( 36 planes ) and Navy ( 14 planes ) , and the air forces of Argentina , and Brazil . Construction nr . ( serial numbers ) 109 and 110 were never built . Operational history . On 18 July 1956 the French government requisitioned 50 aircraft , including 14 for the Navy , from Tarbes - based manufacturer Morane - Saulnier . The first plane was delivered on 9 February 1959 to Naval Air Station ( N . A . S . ) Dugny - Le Bourget , before going to the C . E . P . A . ( directly translated as Aeronautical Practical Experiment Center - in English this would probably be " Flight Test Centre " ) in 1959 - 60 , for the flight tests necessary to develop training programs and materials . The type was also purchased by several countries such as Brazil and Argentina ; 36 planes were license - built by Fabrica Militar de Aviones ( FMA ) in Argentina . The MS . 760B Paris II , with various systems improvements and integral fuel tanks in the leading edges of the wing , first flew on 12 December 1960 . From 1958 to the early ' 60s an MS 760 was used as a flying classroom at the " Colledge of Aeronautics " Cranfield UK . The aircraft was equipped to study stability and control together with performance as part of the MSc course . The 14 MS . 760 were assigned to Flight 11 . S from 9 February 1959 onwards . The last plane , No . 88 , was delivered on 27 July 1961 . In 1965 , MS . 760 No . 48 was briefly assigned to Flight 3 . S based at N . A . S Hyères . From 1970 onwards , all the 12 remaining MS . 760s were assigned to Flight 2 . S based at N . A . S . Lann - Bihoué . In May 1972 they were sent to the S . R . L . On 1 September 1981 this unit became Flight 57 . S ( this flight had been shut down at the closing of N . A . S . Port - Lyautey , Morocco on 15 January 1962 ) . Their missions were Super Étendard and F - 8 Crusader pilot IFR and all - weather training , advanced training for new pilots , proficiency training for other pilots and A . L . P . A . ( admirals commanding the carriers and Naval Aviation ) , and 1st and 2nd Aerial Regions liaisons . Eight MS . 760 Paris were on the unit ' s flightline . After 40 years of service , the aircraft were retired in October 1997 at Landivisiau Naval Air Station . Argentine Air Force MS . 760s were used in combat to suppress the 1963 Argentine Navy Revolt , bombing a rebel - held radio station as well as the Punta Indio naval airfield , destroying several aircraft on the ground . In 2007 , after 48 years of continuous service , the Argentine Air Force retired their last " Paris " . In 2009 , JetSet International Ltd purchased more than 30 MS760s from the French and Argentinian governments , and the type certificate , tooling , parts , engineering plans and drawings from Daher SOCATA . They are refurbishing the airframes and installing new jet engines and avionics and selling them for approximately $ 550 , 000 . A two - ship aerial demonstration team called Team MS760 Aerobatics using the refurbished aircraft was formed in 2009 .
