Have you ever wondered why the flight attendants of a half empty airliner talk people into moving to the front half of the plane? Have you ever wondered why a flying wing can fly without a tail or why the stability of some of these flying wing can be controlled only by computer? Or why a 12 pack stored in at the back of a Cessna can make the plane unstable… It all has to do with two momentums that act on a plane, a positive aerodynamic pitch momentum and a negative gravitation momentum which need to balance each other during the flight.
