Don, flight sims are out there and they are very good, don't dispair.
I believe MS dropped FlightSim several years back (I was a fan too and have the last version in a limited edition tin box at home).
I use X-Plane and like it quite a bit. I think the detail will amaze you. Fair warning, these new flight sims need a lot of computing power to work right.
There is also this site called Steam where you can buy just about anything Sim-related, including different aircraft, airports, scenery, all sorts of add-ons and extras for X-Plane. For example, two of my favorite airports used to be Chicago Miegs and Key West, so I bought them both for the added detail.
There are a couple other sims out there but I don't recall them right now. I did do quite a bit of research before buying, and fwiw 2 years ago X-Plane was the leader. If memory serves, other Sims are also avail from Steam.
Hope this helps.
