My father’s cousin was the pilot (J.B. Underwood) of the only lancaster lost on the first 1000 raid on Cologne. 61 sdqn lanc R5561. I have never found out what its code letter was. Last year his log books turn up, they had been put in a skip, then to the local RAFA inturn passing them on to the Bexley archive centre. Years of trying to do research paid of in the end! I never thought they would have survived.
