RCAF Casualties 1942.

[Artynut]

I have searched various sites to find particulars of the circumstances surrounding the deaths of two RCAF pilots. I find it most frustrating trying to navigate these sites and even to find that when I did get near to the truth, I found conflicting entries. The first was in reference to Sgt. Pilot John Montieth Hubbert. Service No. R66086. KIA 22/23 April 1942. Crash of a Wellington (1X Sqn., RAF) at Sapiston, Suffolk. Parents were named and listed as residing in St. Catharines Canada. on one site he was listed as R.N.Z.A.F. Along with another member of the crew who WAS a New Zealander and listed as such.
The most distressing search I have attempted and failed is that concerning F/Sgt R.N.Langley Service No. R 62755. His CWGC headstone states date of death as 24 February, 1942 aged 24. For some reason I cannot even find where he was from or who his next of kin were. Who he was a pilot with, or which Air Force or if killed in action. I found a date of death difference between sites as the grave marker states 24 Feb. and another sites lists 12 Feb. as the D.oD. Would anyone care to shed light on Sgt/Pilot Langley for me please. I have visited his gravesite twice on past Remembrance Days, and laid a Canadian Poppy/Cross there when visiting my home town of Hornchurch, Essex (UK) Best regards to all, David J.
