8) Can a plane fly with only one engine?

Yeah, pilots easily control and land a plane if one of the engines stops working. The plane will just lean slightly to the side during the flight. But the coolest thing is that passengers will probably not even notice it ?!!!

9) What does a small triangle on the aircraft walls mean?

These triangles are special labels for flight attendants. They mark certain windows through which flashing indicators can be seen. They signal retraction of the landing gear and closing of flaps. If the pilot receives a signal about some problem, the flight attendants quickly find the necessary windows and figure out the problem. And for passengers, this is the place with the best view of the wings. You can get the best photos here.

10) Why are seat belts stretched across your stomach?

When the plane gets into turbulence, it’s tossed a bit in the air during flights. The waist belt will simply hold you in place in case of a more severe shake. Shoulder straps would require more space between the seats, and this is not justified on a plane. In a car, the impact is usually much stronger, so you need that shoulder strap not to woosh through the windshield.

11) Why do flight attendants also have a shoulder strap then?

Flight attendants’ seats are much less comfortable than passengers’ ones. They’re narrower and positioned facing the passengers. Flight attendants need extra protection simply not to fall off their seats if the plane shakes hard enough. Also, they have to help and direct people during potential evacuation, and for that they need to be in top shape.
