IWM caption : High oblique aerial view of RAF Hendon, Middlesex, from the North. At this time, No. 1 Camouflage Unit, No. 24 Squadron RAF, and No. 116 Squadron RAF (whose Westland Lysanders can be identified parked on the perimeter in the foreground), were based there. Further attempts to effectively camouflage the airfield have been made from those in 1941, (see HU 93052 for comparison).
