Airbus A-310/222.

When Singapore Airlines put two of its Airbus A-310 / 200s on sale in 1997, the Air Force seized the opportunity to replace its Boeing 727s. Each  A310 had 12 years of service with a total of 27,000 flight hours. The characteristics of the aircraft met the required specifications, i.e. allowing non-stop transatlantic flights, a considerable payload, rapid convertibility to a cargo version and a potential flight hour sufficient to fly until 2025.
