During 1983 Swissair received four Pratt & Whitney powered A310-221, followed by the protoptype HB-IPE delivered to the carrier in March 1984. Between December 1985 and January 1986 the Swiss flag carrier obtained another four examples of the series 322, while two more A310-300 were aquired from Balair few years later, increasing the fleet to 11 examples. Taken at Frankfurt on 01.08.1990 – the Swiss national holiday – HB-IPD (ln 260) Solothurn made its first flight on 27.06.1983 and was delivered on 14.10.1983 to Swissair. Its career with Swissair ended in 1996, when it was sold to FedEx becoming N448FE. In August 2010 N448FE was withdrawn from use and stored.
