Cause if it had one it would be a monoplane

and if it had three then it would be a triplane AnswerThis was how they designed airplanes. In the early days they build aircraft out of wood and cloth that was glued to the wooden frame. They knew they needed light-weight material. This type of design was not strong enough to make a long, slender wing that could hold the weight. So they built 2 wings and used Cables to make the two wings more rigid. The cables are what give it strength, but it also produces more drag. It wasn't until they learned how to design stronger spars that supported the wing did they finally begin to make monoplanes. They also made biplanes and triplanes that did not require cables.
