FWIW, it seems to me that virtually all cases where someone is nailed for flying without a valid pilot certificate (i.e., without a license to fly), there was an accident, incident, or reported pilot deviation involved to bring the situation to the FAA's attention. There are no doubt many people flying illegally around the country (and not just Alaska) for years without bringing themselves to the FAA's attention. In this particular case, the pilot was flying an unregistered aircraft, which must have somehow triggered ATC's attention (although I have no idea how), and was clearly on the FAA's radar already anyway (and I ain't talking about the radar ATC uses).
So if you're going to break the law, please do it very safely so you don't come to the FAA's attention. :wink2:
