My guess is that G/A Flaps 15 is one and the same as Boeing NG Driver, as Heliport has intimated. Easy for a Moderator to check both users IP's which are logged. I'd also venture a bit further and suggest that in all probability it's none other than FMC apprentice and his other chum too!

One very malicious and dangerous individual with a huge axe to grind. IMHO, this idiot deserves a life ban from Prune at the very least. Better still, I'd like to see his head (his identity) delivered on a platter to MOL and let the FR justice machine sort him out.
Such posts in the current climate are reckless and highly damaging to the whole aviation business and every other professional crew member worldwide.
