How do planes fly

How do planes fly?
Planes were invented long ago in the 19 hundreds and still invented today there are different parts of the plane they are all important. Today I will be talking about the four forces on a plane and in the conclusion I will talk about some special events that planes were evolved in.

The four forces are drag,thrust,weight and lift.Lift is a mechanical force generated by a solid object moving through a fluid.

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

Weight is one of the four forces that make a plane come down.It uses the gravity and its weight.

Thrust is the force which moves an aircraft through the air. Thrust is used to overcome the drag of an airplane, and to overcome the weight of a rocket.

One of the events were the twin towers.People had to jump from the tower to save their life or fall 1,362 feet! The next event was the tenerife disaster which was the worst disaster in history.
