Edwin Swales VC DFC

My fourth cousin was Major Edwin Essery Swales S.A.A.F, VC DFC, of 582 Squadron at Little Staughton, who died on the night of 23rd February 1945, being a long time amateur genealogist, I have for some years been trying to find out as much as I can about him, my question is does anyone know if any of the crew (all survived the crash apart from Major Swales) still survive, the crew were :-

Flight Sergeants G W Bennington DFM, C Dodson DSO DFC, & B Leach; Squadron Leader D P D Archer DSO DFC; and Pilot Officers R A Wheaton RAAF, A V Goodacre RAAF and N Bourne RCAF

Many thanks

John
