Night Air Mail Plane Test Flight Lands in New York, 1924

In 1924, with the success of experimental night operations and increasing business interest in next-day mail, the U.S. Air Mail Service announced plans to establish regular overnight flights between New York and Chicago. Preparations included mounting floodlights and searchlights at airfields and constructing a series of routing beacons and emergency landing fields along the route. The first official flights departed from both terminal cities on July 1, 1925.
