A Little Bit of History Airfield Lighting Design and Construction On Feb. 22, 1921, the U.S. Postal Service conducted a daring night-flying experiment, lighting the transcontinental route with a series of bonfires. Two planes each left New York and San Francisco with loads of mail for the cross-country run. One of the eastbound planes crashed after takeoff in Elko, Nev., killing the pilot. Both westbound planes got stuck in Chicago by a snowstorm. The pilot of the remaining eastbound plane, Jack Knight, survived the trip, but only through extraordinary heroics.

By 1923, the Postal Service had installed similar beacons between Chicago and Cheyenne, Wyoming. This enabled all-night flights across the continent and cut mail delivery time to 29 hours – two to three days less than it took by train. Source: “A History of Air Traffic Control”
