Biplanes

Biplanes are airplanes with two main wings stacked one above the other.

How It Works

Many early airplanes were biplanes because two wings gave extra lift and strength. The Wright Flyer was a biplane.

Why It Matters

Biplanes usually fly slower than modern single-wing planes. Some biplanes are still used for aerobatics and air shows.
