Royal Observer Corps
In 1929 the control of the Observer Corps passed from the county police forces to the Air Ministry, although Chief Constables retained responsibility for personnel and recruitment matters. 1 March 1929 saw the establishment of the new "Headquarters of the Observer Corps" at Hillingdon House, RAF Uxbridge in the west of London, and Air Commodore Edward A D Masterman CB CMG CBE AFC RAF (Rtd) was appointed as the first commandant of the Observer Corps. "Air Cdre" Masterman held this appointment until his retirement on 1 March 1936, and was succeeded by Air Commodore Alfred Warrington-Morris CG CMG OBE AFC RAF (Rtd), who would lead the Observer Corps through the critical period during the Second World War which saw the RAF emerge bruised but victorious following the Battle of Britain of 1940.

On the day of the dedication of the ensign, (Sunday 24th), the approximately 2,000 observers present undertook the first ever uniformed ROC march-past to the accompaniment of the RAF Band, with the Under-Secretary of State for Air, Lord Beatty, taking the salute. The parade then formed into a huge square and the ROC Ensign was presented by Lord Beatty. The Ensign was borne from the drumhead by Observer Lieutenant Pollock, VC. During the parade, Observer Lieutenant Pollock carried the Ensign, flanked by two senior NCOs, at the head of the massed contingent of observers. A film record of these events is held in the archives at the Imperial War Museum. However, in a matter of only a few months, the ROC would again be called upon to meet the challenges posed by a new threat: the Cold War.
