Do penguins have knees?

Looking at a penguin, it may seem that a penguin has no knees but a penguin does have knees, only they are not visible because they are covered by the feathers. A penguin's leg has short femur, knee, tibia and fibula. They appear short-legged because of the feather density, the upper leg bones are thus not visible.

Why can't penguins fly? 

Penguins as birds have wings but they are evolved in such a way, that they can swim than take a flight. Birds that fly have hollow bones, which makes them adapt to flight but penguins have dense bones, which are adaptative for their diving. Penguins use their wings as limbs for swimming deep and a penguin can swim around four to seven miles per hour. Although, they may jump in water which may look like they fly. But essentially penguins are flightless aquatic birds.
