Flight is the ability to move through the air, and it can be seen in many forms, from birds soaring in the sky to airplanes like the Boeing 747 transporting people across the globe. Birds use their wings to lift off the ground, while airplanes rely on engines and wings to create lift. This fascinating phenomenon allows creatures and machines to travel great distances quickly. The science behind flight involves principles like lift, thrust, and drag. Lift is generated by the shape of the wings, while thrust is produced by engines. Understanding these concepts helps engineers design better aircraft, making air travel safer and more efficient for everyone.
