Safety is the paramount concern for most airlines, because crashes and mishaps can cost millions of dollars and destroy hundreds of lives. To this end, airlines often go to extreme ends to protect their human cargo. Unfortunately these ends are all too frequently not enough to prevent the tragedy and heartbreak of an airplane crash.
Seatbelts, flotation devices, and crash positions are common precautions airlines take to secure the safety of their passengers. During the preflight announcements the flight attendants will go over how to react during an emergency, demonstrate how to use an oxygen mask, and show the passengers where the emergency exits are, but a plane crash is usually so chaotic that even these well planned safety precautions fail to save many lives.
