I) IN THE BEGINNING

There was no metal

There was only wood.

This meant that wings were short.Short wings need to develop as much lift

as possible.

III) Frontal Wing Forms

This is the appearance of the wings when

looking at them from the front.

The specific design depends on the needs

of the aircraft.
