I think this whole episode has illustrated how meaningless the concept of regulatory oversight at a national level (or indeed EU level) has become in aviation, I mean the whole thing being dependent on the letter painted on your plane etc or where you live or whose air you happen to frequent. In an ideal world the USA and the EU would just agree on common standards for licencing, airspace etc, everyone's lives would be so much easier. Not going to happen, but would be nice.
