Oops - sorry Rover. No disrespect intended. As I was typing it, I was sure I had missed someone off, but in my advancing years I couldn't think who the heck it was - many apologies! Greatest respect for engineers - they've saved pilots from the worst effects of their errors on several occasions (both the airborne and the ground varieties). A tad ungrateful, therefore, to have neglected them on this occasion. They have, of course, also contributed much of great value to PPRuNe. The worth of the airborne variety continues despite all beancounters' efforts to kill them off - VC10, L1011, DC10, Concorde, B727, A300, 74C etc. etc., plus the worth of the ground-based variety will never end.
Long may they (and many others) continue to enhance the worth of PPRuNe to all!
