Blue Spruce
Its a very North Atlantic VHF/VOR/NDB only route. The longest leg over water is about 300 mn. In WWII it was a very popular shuttle route for military a/c to travel to Europe. The only hazards were severe cold, crappy WX, poor NAVIDs and lousy comm. Asside from that, it was the safest way to get there.....Regards...Paul
