What are the consequences of a pilot flying a scheduled airline flight with passengers deviating from a flight plan to perform a random maneuver?
Say during a normal landing procedure, he spots something interesting not in his normal flight plan nor in the normal landing procedure, and decides to do a fly over, then returns to land the plane normally.
I imagine he would be fired from his company, but would there be legal action against him? If so, what would be the severity of the crime? (We can assume the US or Europe).
