Beacons Replace Bonfires
The Post Office, Army, and Commerce Department worked together to develop better navigation technologies, especially a system of lighted airways.
By the summer of 1923, air mail pilots could fly from Chicago to Cheyenne, Wyoming, guided by 289 beacons and 39 lighted landing fields. The lighting of the New York-San Francisco route was completed in 1925, and the system was soon extended to other routes. |
