The first seven two-way communication stations, developed by the National Bureau of Standards, were installed by October, 1928. The establishment of the Aeronautics Branch in the Department of Commerce in 1926 brought renewed efforts in radio communication and navigation. Air Mail Service in 19 but were soon discontinued. The first experiments in using radio for both air navigation and two-way communication were conducted by the U.S. The beacons and radio ranges were the navigation aids (or navaids) that were indispensable in enabling the airplane to evolve from being a marginal, fair-weather, daytime-only supplement to America?s transportation system to becoming a major, all-weather transportation provider in the course of 20 years. During that same period, pilots were guided in instrument flight, and in daytime visual flight, by the Four-Course, Low-Frequency Radio Range. The article I wrote for the July, 2009 Touch & Go, "Airway Light Beacon Archaeology," explained my interest in finding the remnants of the beacons that guided pilots at night from the late 1920?s into the 1950?s.
