I know it was brought up before, but I wanted to add this thought. In my case, I am in Florida and cover the Atlantic and Gulf coast. So I put up 10 stations on both coasts so I could have an airbase. Got a mission very close to one of the bases but 288km from the air station. Even moving the station will mean it could be a 100km flight to get to a station further down the coast. I believe that a base for every 5 or 6 bases should be considered.
