Bomber Command aircrew were debriefed as a crew by Station intelligence personnel immediately after each and every operation.

A copy of each report was then telexed to the relevant Bomber Group HQ for analysis. After the war, most of these original reports were destroyed. The information contained in them, though, was also used( sometimes in shortened form ) in the relevant Squadron Operational Record Book ( ORB ) and these can all be freely seen and copied at the Public Record Office in London.

Some original debriefs survived in private hands and occasionally appear at aerojumbles or on ebay - I have one for interest in my collection ( Lancaster HK684 on a raid to Wiesbaden 2-3 Feb 45 ).
