The police officer allowed everyone else onto the airfield before 9.00am, locals and people leaving the country. I only wanted to preflight. I had no intention of departing.
"Everyone" may not have been what you think, they could just be people working there going to the office or based pilots going to the aircraft. The (very) few police crew at the gate there know us the based pilots and employees there by face not to mention the apron entry permits for cars issued by CAA long time ago.
Nobody leaves the country from Megara since its not a port of entry/exit.
Police check people who go in to the apron for simple local security reasons and I am happy I park my aircraft there and not every "Everyone" can enter there freely.
I understand where (in aviation world) you come from and why these incidents ruined your day. GA in southern Europe is nothing like US or northwest Europe. Based pilots learn to compensate for it, visitors from other GA flourishing lands on the other hand, understandably, react.
