Air Commerce Ltd

On the 29th of August 1939, prior to the outbreak of war on the 1st of September 1939, the British government started to implement the Air Navigation (Restriction in Time of War) Order 1939. That ordered military takeover of most civilian airfields in the UK, cessation of all private flying without individual flight permits, and other emergency measures. It was administered by a statutory department of the Air Ministry titled National Air Communications (NAC). On the 31st of August 1939, all flights to mainland Europe were briefly suspended, later reinstated under the organisation of NAC. By 1 September 1939, most of the aircraft and facilities of British Airways Ltd (BAL) were transferred from Heston Airport to Bristol (Whitchurch) Airport, and to Exeter Airport. Similarly, landplanes of Imperial Airways were transferred from Croydon Airport to Whitchurch, while others were temporarily dispersed to Coventry (Baginton) Airport and Exeter Airport. Imperial Airways' flying boats were transferred from Southampton marine aerodrome to Poole Harbour, Dorset. All the usable fleets of private air transport companies were dispersed: Air Commerce Ltd which had been absorbed in to Olley Air Services Ltd was dispersed to Ronaldsway Airport, I.O.M. in September 1939.
