I was watching "The Aviator" (Christopher Reeves flying airmail) and they
mentioned airway beacons. Those were rotating lights much like we still have
at airports. There may still be one of those airway beacons north of York, PA
along the Susquehanna Trail.
It wasn't that long ago that the last of the Red and Blue airways were
decommissioned. There was one in North Carolina along Cape Hatteras, and
Alaska was full of them. They used VLF (Very Low Frequency) nondirectional
beacons.
