 One of the keys to Allied victory in Europe was the Norden Bomb Sight, which enabled bomber squadrons to target Germany's war-making industry and infrastructure much more accurately.The military repaired and calibrated the bombsights at Brookley in a secret facility, still standing and in use today.In 1944 with the closure of the Army contract flying school at nearby Bates Army Airfield, Air Transport Command operations were shifted to Bates to alleviate runway traffic at Brookley.
