I'm researching a past relative who was named Eric Chadwick, Flying Officer 157671, Squadron 144 who died aged 24, on 26th April 1945, returning from a mission in Europe. His plane was shot down over Norway or the North Sea, no body was recovered. I don't know anything other than that. Would just like to know which operation he was on when he died, where he was stationed, what planes he flew, which operations he went on. Anyone help?
