High Wing Drifter... haha till i read a subsequent post i thought you meant Elite the Space Trading Game from back in the day. Great stuff but i'm not sure docking in a space staion is good practice for ILS landings!
As for Xplane... Its the only one i've used really as i have mac. I have to say to say it is very good though and gets the physics just right. However it is severely lacking in frills. On mine the whole of the UK is ocean except for the airfields. I did find a demo of uk scenery that limited you to the southhampton area but this was just non-descript greenness really. That could be due to my low spec computer. Anyone been able to make it look pretty?
