Hi Gareth, welcome to the world of X-Plane 1. The best place to purchase X-Plane is probably here (ships from the U.S). You can either purchase the DVD's or you can get it on Steam (download). You could also try Amazon and see if they ship from the UK. 2. I would recommend looking at this post on Avsim about some add-ons to get, and, assuming you like to fly in Europe you should take a look at TDG's airports. For some payware aircraft, I would suggest the LES saab 340, Flight Factor 757/777/A350, SSG 748, FlyJsim 727/732, Jar Design A330, and some Coronado's. Those are just a few of my favorite aircraft, but their are many more available. A few more aircraft that aren't out yet, but will hopefully be soon are the PMDG DC-6, IXEG 737-300, and the Rotate MD-88. 3. When you buy X-Plane you either get 8 DVD's which include the default aircraft and terrain, or, if you bought from Steam you download the terrain DLC separately, but you don't pay extra. It includes a few hundred default airports as well. You can then download more scenery for airports, buildings or more detailed terrain from places like here, x-plane.org, and flightsim.com. Aerosoft has provided a few default airports for x-plane, all in Europe. 4. X-Plane 11 will (most likely) be the next version of X-Plane. I'd expect it to be released sometime between 2016-2018, but I don't know for sure. If you have any more question, feel free to ask, Jon
