Air Traffic Control Game - Airport Madness 2
Airport Madness 3
Play Radar Air Traffic Controller, a free online game on Kongregate
All designed by bigfatsimulations (who used to be an air traffic controller himself) and they are pretty intense. I have the full versions which you can buy via the first link, but two free 'samples' are below that. The first link is the most realistic and takes some time to get used to.
I'm planning to stay somewhere nearby again, but not sure where, left it a bit late thanks to being busy and the premier inn is now booked up!
Going to have a phone around tomorrow.
