If you're a nervous flier, then chances are that you watch the flight attendant for signs of panic during bouts of turbulence to figure out whether or not the plane will crash. But the captain and cabin staff will tell you if the plane is in trouble, according to a crew member.

"The captain will give you the same information that we know if there is time and then we will begin emergency landing procedures," the anonymous flight attendant said. "My job is to make sure we all get out alive, so of course I would want you to be as prepared as possible."
