Avia, Paola if I implied US airports wouldn't hack it at LHR..I certainly didn't mean that in the slightest..it was just to get the definition of BUSY ATC sorted in the aviation context. I am certain that given role exchanges twist LHR and US ATC, the world would be a little more colorful, a tadge less stuck up and a bit less arrogant!
Yes..AMS and this DIRECTOR thingy..strangely after operating in there for a pretty long time..since 1980 ish..I can't recall.."call director call sign only".. Must either be early onset...or I am so gash they don't trust me!!!
