I think the main problem in Spain in general whether it be aviation or any other form of sport/ activity is that it is heaped in red tape and legislation, if you think we have it bad in the UK with the CAA go and live in Spain. The UK makes it looks easy compared with Spanish authourties many of whom don't even know the law themselves!
Just try buying a car for example providing you have the right paper work then you will just spend about 4 hours visiting about 3 different offices and in each place you will have to go to at least 3 counters! A nightmare and the question i ask is why?

what for why don't they adopt a simple system like we have in the UK? ohh and lastly only residents who have a residents ID can buy a car and BTW that takes 3 months to get!!!
welcome to Spain
