This aerial navigation chart was published in September of 1944 by the United States Coast & Geodetic Survey. The sheet covers a broad area across the states of Washington, Oregon, Idaho and Montana between Puget Sound and the western portions of Yellowstone.
Conspicuously marked Restricted in the upper left and lower right, the image is filled with sensitive military information on radio frequency, flight traffic patterns, prominent navigational beacons, and prohibited areas. Color is used to reflect the elevation of the terrain, and topographic detail is shown in contours.
These charts were produced in significant quantities throughout the Second World War, but this particular example comes with several pieces of related ephemera. Restricted instruction cards from early 1945 provide direction on air-sea rescue, the wind force prediction table, lost plane procedures and fighter director vocabulary. Additionally, a six page hand-typed report (also marked Restricted) details extensive information on Fighter Direction Radio Procedure, including the use of key phrases (Over — Out), weather reporting and more.
