Found a free Flight Simulator called YSFLIGHT. The graphics aren't as good as they could be ( think Final Fantasy 7), but for a one-man team, the guy has done a wonderful job. There's about 80 aircraft to fly (most of them are army/navy aircraft), and you can have dogfights and bomb bases and the like. Its quite fun (landing, however, is NOT!), so I suggest you go to Google or similar and search for "YS Flight". Let me know if you get it.
