A grass airfield, with eight blister hangars and one A1 hangar, was laid out soon after the outbreak of war and the first squadron to operate from there was No. 235 Squadron RAF using Bristol Blenheims for convoy escort and anti-shipping operations in the North Sea. These were then replaced by the Lockheed Hudson.
A meteorological observation unit No. 405 Flight of Bomber Command was set up as part of the effort to gain important weather information. When Coastal Command took over all the meteorological units this became No. 1401 (Met) Flight and received a greater variety of aircraft. As well as Blenheims it operated Spitfires, Gloster Gladiator biplanes and Hawker Hurricanes. These aircraft were all used to take measurements of temperature nd humidity; from 40,000 ft downwards in precise areas. In August 1942 the Flight was made into a Squadron - No. 521 - with Hudsons Hampdens, Mosquitos and Venturas. The squadrons Mosquitos would operate deep into occupied Europe to take measurements over target areas; known as "PAMPA". In 1944 the squadron moved to the other satellite for Bircham Newton, RAF Langham
