Though one should get a warning so the player could feel the effect of a no fly is coming on so they know to land if they don't want to chance it or they can choose to try to though it out or fly through it. Or else it may get very annoying for some players.
fancy flying could be possible, maybe at a certain level, or once one's flying skill gets to a certain level, or it could be a different independent skill, aerobatics or somesuch, different then basic flight skill & used in different situations.
