This is slightly off thread, but relevant, and may clarify some things, and at the same time make them even worse.
There are huge numbers of people out there with no aviation qualifications what so ever who take great delight in flying their virtual 747 from airfield A to airfield B using whatever flight simulator package appeals to them.
With the advent of the internet, and now broadband, they can even do this real time with other people, and there are now also add on packages available for the simulators that allow another person to act as an air traffic controller and control all these "virtual" aircraft. It used to be just pop up text messages on the screen, but broadband opens up the possibility of "real" audio, in real time.
I've also heard more than a few people express the idea that they'd like to fly their "virtual" flight in real time, mirroring exactly what is happening to the real flight, by using live ATC feeds such as the ones that have been discussed here, although they'd not be able to respond on line to the controller, or I for sure hope that they'd not be able to!!!
I'm not even going to start on the road of discussing the validity or otherwise of such practices, but they are happening.
In some cases, the people involved take it VERY seriously, to the point of obsession, and enemies have been made over very complex arguments in these areas.
To those of you that ATC for real, this probably looks like your worst nightmare. It may well be, although for training purposes, the thought of using internet virtual flyers, if they know what they are doing, might add some realism to the scenarios.
