Looks like that might be on route #19 which went from Atlanta to New York. Think it’s this beacon, number 14 on the 1933 strip map (map isn’t aligned north, north is kinda to the top left)
Might be a while before we get to this route but hopefully one day!
Here’s some extra info about the beacon from the most informative and helpful DreamSmithPhotos Arrows website: 32 A-NY Reidsville DOCILF
This route was originally operated by Pitcairn. I really hope we get a Pitcairn Mailwing in MSFS one day. Hopefully Golden Age Simulations will remake their FSX/P3D one for MSFS.
