aviation

Boeing Air Transport, a precursor of United Air Lines, trained the world’s first stewardesses in Cheyenne beginning in 1930. This and other aviation-related industries boosted Cheyenne’s economy through the end of World War II and beyond; the stewardess school finally closed in 1961.

Early mail pilots eyed roads and railroad tracks as they flew. Soon, the U.S. Airmail built a transcontinental system of night beacons and landing fields. In 1931, low-frequency radio signals from Medicine Bow were the final link–like the railroad’s golden spike 62 years before—in a navigational chain allowing on-schedule, cross-country, all-weather flight.
