I think that we outta have a server to simulate the something like the mid-70s or 60s, I just think that would be cool, with the decreased fuel prices and old aircraft. It would be a time consuming undertaking, but I have faith that the awesome staff here could pull it off. If you have anything to add feel free.
I think the team allready announced that they will make a retro server, but I think it will require some research and therefore some time...but perhaps the team has already new information on when this server will start. So it's already in planing...
