No. 31 Operational Training Unit

No. 31 Operational Training Unit was a British military aviation training center primarily active during World War II. Its purpose was to train new pilots and crew members in operating specific aircraft, such as bomber planes, ensuring they gained the skills needed for combat missions. The unit provided hands-on instruction, simulation exercises, and preparation for operational deployment. Essentially, it served as an intermediate step between basic flight training and active combat service, helping crews develop the expertise required to perform effectively and safely during wartime operations.
