Ahhh my Sarcasm alarm has sounded.... Mr Mil please accept a sincere apology someone based largely on the West Side, for what was an honest late-night oversight.
However... on a private flying forum I think the question of Military Middle Airspace Service may be irrelevant; and there is at least one more unit that routinely provides service above FL100... Plymouth (Mil) and maybe Brize still do?...but I wouldn't want to get into point scoring?
One question, how on earth did you find another 139 people who actually work at West Drayton? ...keep up the good work.
