AIR Vice Marshal Graham Lintott, Chief of the Royal New Zealand Air Force formally opened RAF Northolt's Sir Keith Park Building on Battle of Britain Day.
He was welcomed by Station Commander Group Captain Tom Barrett before unveiling a plaque at the entrance to the building and viewing the exhibits on display.
AVM Lintott was accompanied by the New Zealand Minister of Defence the Hon Dr Wayne Mapp who also joined the visit to the 11 Group Bunker at RAF Uxbridge following the opening ceremony at RAF Northolt.
The Sir Keith Park building is the WW2 Sector Operations Room from which aircraft were controlled in "Sector Z" to the west of London.
The station has been undertaking a heritage project to restore the plotting room and create a museum to display artefacts from the station's history.
The building was named after New Zealander Sir Keith Park who was station commander at RAF Northolt 1931-32 and Air Officer Commanding 11 Group at RAF Uxbridge throughout the Battle of Britain.
Park was the brains behind the integrated air defence system which did so much to protect the UK in the Battle of Britain.
