Question

why is the shape aeroplane designed like that?​

Answer 1

Answer:

Airplanes have wings, just like birds. They also have a light skeleton (or framework) to decrease their weight, and they have a streamlined shape to decrease drag. ... Airplane wings are designed to create lift by changing the pressure, rather than by flapping them up and down.
