Every day a number of commercial and private planes take off and land at the Port Elizabeth Airport, but outside the airport there are two planes that just hang around, not going anywhere. The one is a Piaggio P.166, a twin-engine pusher-type utility aircraft developed by the Italian aircraft manufacturer Piaggio Aero. In the South African military the aircraft is known as the Albatross and was used by the South African Air force from 1969 to 1993.
