I agree that it may be a little strange, but I don’t think European governments have taken drastic measures like the US has. The US has always been a little paranoid and they have taken it to a whole new level in the aftermath of 9/11. How many times have jets been hijacked worldwide and yet, flight crews still allow passengers to visit the cockpit? As far as there being a passenger in the cockpit at the time of landing, I don’t believe this would have had anything to do with what may have happened. Although, he could end up being a great witness in what may have actually transpired in the cockpit during the last few minutes of the doomed flight.
