At the end of 1975 the Belgian Government acquired two Boeing 727-29QC airliners from the national airline company Sabena. Both aircraft were to replace 4 Douglas DC-6B's with n° 21 Squadron based at Melsbroek. Although modern for their time both 727 were always somewhat short legged and had to make several refuelling stops to fly to the USA. To overcome this shortcoming both 727's were replaced by Airbus A310's in 1998.
