DC-7C Freighter "Adriatic Sea" taxies out from the KLM Cargo sheds on Heathrow North along the taxiway that is now the Northern perimeter road. KLM were attached to the cosy Northside, their passenger operation only moved to Heathrow central when the long-haul airlines moved over around 1963, then the Freight operation moved Southside to the new Cargo Terminal in 1969, the 50th year of this great Airline.
