RAF Madley was an RAF airfield situated in Herefordshire, England. The site opened as a training centre for aircrew and ground wireless operators on 27 August 1941. In 1943, the grass airfield was reinforced with Sommerfeld Tracking and the centre's population rose to about 5,000. The site was visited in 1944 prior to D-Day by US General George S. Patton, and later by Rudolf Hess (who had been held prisoner near Abergavenny) on his way to the Nuremberg Trials in 1946.
