With such aircraft like the A2A L. 049 "Constellation" and the Boeing 377 "Stratocruiser" or all those aircraft from Just Flight like the Vickers "Viscount", the Douglas DC-6B, or the De Havilland "Comet" it is bad, that we have nearly nothing in AI, nothing on the ground and not really a lobby in the Simulation industry to look at this Retro-market...
I have not the time and the knowledge for search, looking for timetables and compile "my own traffic" ... In my eyes this is a very sad situation. I am not a fan from Airbus and other Nintendo-style-aircraft in the simulation lookimg for more the historical aspect of flying.
