European Aviation Safety Agency
You would have thought that their mission was contained in their title. But no. Like every other European institution all they ever do, in this case for €150 million a year, is bash out rules and regulations. Quite why, only they know, but overall effect of their activity has been to make it highly likely that you'll break a rule - if for no other reason than they changed something - again. I'm sure that if an alien arrived in an EASA office (have you seen their locations?) he would think he's stumbled across a paper factory.
The only good EASA does is to prevent the clowns who work for it interfering elsewhere in the EU system. We do need a central authority, but maybe they should make a new start by eliminating rules and regulations. Let's face it, their task is pretty simple. It's to stop aircraft from bumping into things and things bumping into aircraft.
