- "Cleveland Greets the First Night Mail Plane," July 1, 1924 - Early pilots depended on visual landmarks, preventing reliable nighttime navigation. When the postal service took to the skies with transcontinental mail delivery, a lighted pathway was formed to guide pilots at night. Throughout the 1920s, a series of powerful light beacons was built, eventually stretching from New York to San Francisco. This image celebrates Cleveland's first night mail flight.

- Loading Air Mail Plane Using Floodlights, Fort Crook near Omaha, Nebraska, 1924 - Transcontinental air mail pilots relied on a string of powerful light beacons to navigate sections of the New York to San Francisco route at night. They flew night mail planes equipped with illuminated instrument panels, navigation lights, and landing lights. At airfields along the way, floodlights helped workers inspect the planes, refuel, and unload and load the mail.
