Spitfire X4593 of 266 Rhodesian Squadron Royal Air Force, was based at RAF Wittering; on 22 November 1940 the plane crashed near Holme Lode Farm, Holme. At the controls for what was intended to be a routine training flight was Pilot Officer Harold Penketh. During a climb to altitude with two other Spitfires he was seen to break formation entering a dive from which he failed to fully recover.

We had good evidence about the location of the crash site of Spitfire X4593 thanks to a geophysical survey and metal detecting carried out by Cranfield University, in August 2015 which successfully located the aircraft. The excavation began in the week of 5 October, 2015 and was carried out by Oxford Archaeology East.
