During the Second World War, the Germans began to build an airfield in occupied Holland “as a distraction”: all the structures and equipment in it were knocked together from boards and plywood. The work was carried out in an atmosphere of strict secrecy.
Until a British bomber flying over a fake airfield dropped... a wooden bomb on it. It is not known whether the Germans appreciated the English humor, but they understood the hint: construction was stopped.
