The Saab 105 is a Swedish high-wing, twinjet trainer aircraft developed in the early 1960s as a private venture by Saab AB. The Swedish Air Force, which had opted to procure the type for various roles, issued the aircraft with the designation Sk 60. The Sk 60 entered service in 1967, replacing the ageing De Havilland Vampire fleet. The Swedish Air Force bought a total of 150 aircraft and another 40 were exported to Austria, designated Saab 105Ö. The Saab 105 is also the aircraft used by Swedish Air Force display team Team 60 and was formerly used by two display teams of the Austrian Air Force, "Karo As" and "Silver Birds". Development In 1959, development of what would be subsequently designated as the Saab 105 was initiated by Saab. The company had decided to develop the aircraft as a private venture and intended for the type to be capable of serving in a wide variety of military and civil capacities. In a military capacity, the 105 can be operated as a jet trainer, conduct aerial reconnaissance and ground attack, and a limited interceptor capability. Amongst the diverse roles planned for the aircraft, Saab proposed a four-to-five seat business jet cabin configuration which was intended to be used by corporate customers. At the time, the 105 was one of the only small European aircraft to be equipped with turbofan, which was reported as of interest to prospective business customers. The 105 was intended to launch Saab into the business jet market; however, ultimately no such customers emerged for the type and thus Saab elected to focus its interest upon military customers instead. Early on, the Swedish Air Force had formed a commitment with Saab that, contingent upon satisfactory performance of the prototype during flight testing, that an order for at least 100 aircraft would be placed. In December 1961, the Swedish Government announced that it had authorized the Swedish Air Force to sponsor the development and manufacture of a single prototype Saab 105 in a training configuration. On 29 June 1963, this first prototype conducted its maiden flight. The flight test program soon revealed the type to have good handling qualities and to be capable of performing aerobatic maneuvers. In March 1965, a single prototype was dispatched to Turbomeca's facilities in Pau, Pyrénées-Atlantiques, Aquitaine, France, for further flight testing of its Turbomeca Aubisque powerplant. On 6 March 1965, the Swedish
