How Aeroplanes Fly

Planes were invented a long time ago. Probably before your parents were born. Not many people know how to fly a plane and not many care.

Lift is the force that directly opposes the weight of an airplane and holds the airplane in the air. Lift is generated by every part of the airplane, but most of the lift on a normal airliner is generated by the wings. Lift is a mechanical aerodynamic force produced by the motion of the airplane through the air.

Thrust is a force or a push. When a system pushes or accelerates mass in one direction, there is a thrust (force) just as large in the opposite direction. In math and physics, this is described by Isaac Newton's second and third laws. Thrust is used to describe how well a type of engine runs.

Drag is the force that opposes an aircraft's motion through the air. Drag is generated by every part of the airplane (even the engines!).

Weight is the gravity when you land the plane,Helicopter,Hot air Balloon  and birds. And to overcome the lift to get more weight I think you just need to get a bigger plane that could fit more people in the plane.
