I have been using the ATC-SIM in guest mode for some time now but one of the things that really steams me is, when sending a flight to it's exit point, another plane will pop on the screen inbound within the 3 miles and at the same altitude and RED ensues! Is this done on purpose or is it a glitch/happenstance?
Another pet peeve, when landing planes, all of a sudden the next departure is using your runway! Why can't I assign the runway to take off from as well? Can I fire the ground controller? :)
Love the game otherwise and I find i spend probably way too many hours playing! :)
