A Little Bit of History 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.

A Little Bit of History Also, in 1921, rotating beacons on towers replaced the bonfires on a segment of the cross country route through Ohio. 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.
