The Butt Report
was a report prepared during World War II
which revealed the widespread failure of bombers to deliver their payloads to the correct target.
At the start of the war, RAF Bomber Command
had no real means of determining the success of its operations. Crews would return with only their word as to the amount of damage caused or even if they had bombed the correct target. The Air Ministry
demanded that a method of verifying these claims was developed and by 1941 cameras mounted under bombers, triggered by the bomb release, were being fitted.
The report was initiated by Lord Cherwell
, a friend of Churchill
and chief scientific advisor to the Cabinet. David Bensusan-Butt
, a civil servant in the War Cabinet Secretariat and an assistant of Cherwell, was given the task of assessing 633 target photos and comparing them with crews' claims.Longmante References
