We may never know what happened to that Malaysia Airlines 777, but there’s plenty more we should know about flying, even domestically. Here are some little-known truths of aviation as shared by pilots and flight attendants:
Lavatory doors don’t really lock: They can be opened from the outside by just sliding the “occupied” sign to one side. This isn’t so attendants can catch “mile high club” wannabies, but so they can be sure the lavs are empty on take-off and landing. And those ashtrays in the lavs? Even though smoking has been banned for decades, the FAA still requires them.
