U.S. Air Force 52-6218 livery for the Aero Design and Engineering U-4A. This is one of three aircraft used primarily by the army for VIP transport duties. Early in the 1950s the Aero Commander was known as the L-26 changing to an Army YL-26A liaison aircraft in 1952, then in 1962 it became a U-9A. The real world aircraft was retired in 1978, then in 1988 shipped to the March Field Air Museum. Between 1988 and 2002 it was painted and displayed with the grey USAF U-4A paint scheme. This is a texture only package and requires the FlightSimOnLine Aero Design and Engineering Aero Commander 520 (ac520v31pkg.zip) base aircraft.
