Fake pilots exist the world over. I think we've all heard of pilots who have flown a few hours in Bravo India Charlie or Pen Echo November. But some 20 years ago I gave a statement as an "expert witness" in case (subsequently lost) where a candidate turned an ATPL subject (set by a well known national authority) "fail" into a "pass". There was no doubt that in my mind, for a whole variety of reasons, that the pass was "forged" but this guy got his ATPL. So unfortunately, they are all around us!
