Sannatuu: Do you know if this could be the same navigator G Sproates who became Commanding Officer of 10 Squadron from 1955-56, when the unit was flying the Canberra jet bomber? Has participation in the air attacks on Egypt in 1956 ever been mentioned in the family, for example? As it happens, I've just started trying to find out a bit more about him for the Squadron Association website and, from some of the bits I've found online, I'm wondering if there might have been two of them around post-war. One retired in 1971 as a Group Captain and if you're correct about a death in the 60s, then it does seem that there were two after all.
