How Do Dragons Fly?

Weight and Skeletal Structure
Most dragons are large, fire-breathing, flying reptiles. So how do they fly? Well, in order to fly fast and stronger a dragon needs a lots of muscles and muscle structure, most of them are near the chest, and stuck to the wing area. This helps them lift their wings and fly efficiently. Another theory is thatt dragons have evolved an extremely light bone structure, similar to the ones birds have adapted to. Below is a picture of a bird muscle structure.

As you can see, the bones are very light and small. The muscles are mostly centered around the wings and chest to promote flying.
