JT, I have not been on pprune for a bit but the last time I was on and these type of questions were being asked (especially by non-english speakers) the opinion of the day seamed to be "don't give out info that can be used to good effect by a potential wrongdoer".
Now, I do not know mb339 from Adam. He may be a thoroughly good chap, on the other hand he/she could be a complete bad egg!
What do I know?
Apologies if I have upset anyone, but what is the current thinking? Has the potential terrorist threat from a rogue a/c gone away?
