One would not normally think of everyday life objects, apparently as inoffensive as a pen or a cup of coffee, as being a real threat to the safe operation of a commercial flight. Yet, leaving them unsecured or forgotten in a cockpit could rapidly turn them into real trouble makers. Common sense generally instructs anyone in a cockpit to maintain an orderly environment. However, over the past decade, serious incidents involving unsecured or forgotten items have continued to happen. For the most part, being complacent is not intentional. It just happens. But in view of the possible consequences, truly the cockpit must remain clean and tidy at all time during flight.
