Reit, 1980]
Another enemy decoy, built in occupied Holland, let to a tale that has been told and retold every since by veteran Allied pilots. The German "airfield," constructed with meticulous care, was made almost entirely of wood. There were wooden hangers, oil tanks, gun emplacements, trucks, and aircraft. The Germans took so long in building their wooden decoy that Allied photo experts had more than enough time to observe and report it.
The day finally came when the decoy was finished, down to the last wooden plank. And early the following morning a lone RAF plane crossed the Channel, came in low, circled the field once, and dropped a large wooden bomb.
