As an American that has been flying for a European carrier for almost two years now, I must say that most of the controllers here are wussies. I am absolutely flabergasted at the slot times (CTOT) we get because of congestion (especially Austria), only to get airborne and hear very little on frequency. Vienna controllers must have a clause in their contract that limits them to handling no more than 3 a/c at a time. What a joke. ATC here in Europe has equipment that is 20-30 years newer and better than in the States, yet they seem to be capable of so much less! I wince when I imagine how euro controllers would manage Chicago O'Hare, LAX, or JFK approach on a normal day. A busy day would absolutely eat their lunches!
