Over here on this side of the pond we lost one of the best airways marker systems ever invented sometime around 1960 when they shut down the airway marker beacons that were put there for the early mail pilots....
...for me it was quite traumatic to lose both the airways beacons and the radio ranges......but I can still close my eyes and see the airway marker beacons ahead of me in the night and know soon the flight would end successfully when I skillfully hit the cone of silence in my headset..
Aahhhh the good old days.......but we still have the ADF to bring us back in time...
