Aircraft Recognition Training Page: Short Sunderland. Issued by the U.S. Naval Training School in Columbus, Ohio in December 1942, this page taught sailors and airmen to instantly identify the British Short Sunderland flying boat, a long-range RAF Coastal Command patrol bomber used for maritime reconnaissance and anti-submarine warfare. Paired photographs and official silhouette views, front, side, and plan, drilled recognition skills that could mean the difference between friend and foe in a split-second sighting at sea or in the air.
