I may have the opportunity of going to Bologna in April. I was there many years ago (1997) when the terrace was still open (now closed). However, there were also many good vantage points around the airport. By Italian standards, photography then aws no problem at all. I notice that there are few recent shots on Airliners taken there. Have things changed? Does anyone have experience of the current situation there, and the attitude of the local police or airport police?
