Sgt. Wightman was killed when Avro Manchester I L7485 ZN-D of 106 Squadron was lost on a minelaying mission to the 'Deodar' area, the code name for Bordeaux. The Manchester is assumed to have crashed in the English Channel, with the loss of all seven crew members. It was the crew's first operation. The body of the pilot was washed up at Weymouth, and four others were found in Brittany. The remaining two have no known grave, and are commemorated on the Runnymede Memorial.
