This has happened a few times in EIDW,I heard it happen a few weeks ago.The controller tried to get as much information from the pilot ,the altitude they were at,from what direction it came from,things like that,but no one was caught for ,well i didn't hear any reports on it in the media anyway.
I suppose it is quite common but goes unreported unless some one is caught.Goes to show how reckless people can be,you can understand kids they dint understand the full implications but adults that is a different story.
