There are lots of things that flight attendants don’t talk about to passengers. For instance, they can open the bathroom doors from the outside, but they would never tell you that! Also, a plane can technically run on one engine, and the crew has a way of putting out engine fires in the air. Terrifying (and cool), huh?

Have you ever had a flight attendant ask you to raise your window shade just as the plane is about to land?
