According to published unofficial sources, Hurricane L1645 was shot down by a Messerschmidt Bf 109 of III/JG 26 piloted by Oberleutnant Joachim Müncheberg at Huldenburg, Leuven, Flemish Brabant at 12.40 hrs on 15 May 1940. It was claimed as Joachim Müncheberg's fourth victory in air to air combat, and took place "Near Overijse"
Crew of Hurricane L1645:
Sergeant James Leslie Clutton Williams, RAFVR, 741421, age 21, posted 15/05/1940, as missing presumed dead, and is commemorated on the Runnymede Memorial. There is a post script: in 1982 the wreckage of a Hurricane was excavated, and it is believed to to be that of L1645:
"The Huldenberg Hurricane was excavated 25 years ago in the presence of a man of the Belgium Aviation Museum Brussels, on Saturday September 11th 1982 . According to local witnesses it had crashed somewhere around May 15th 1940. The engine and parts of the cockpit were found at a depth of about 5 metres, together with a few human remains of the pilot and a piece of parachute cloth, suggesting that the pilot had died still holding the control stick and had crashed to his death."
The above report implies that the pilot was still in the cockpit of Hurricane L1645 when it crashed, but that not enough of his remains survived to make a definite identification.
