The Earth pulls everything down towards its centre, this pull is
called the force of gravity. Humans are not physically designed to
fly. We cannot create enough lift to overcome the force of gravity
(or our weight). It's not only wings that allow birds to fly. Their
light frame and hollow bones make it easier to counteract gravity.
Air sacs inside their bodies make birds lighter, which enables
smoother motion through air. The shape of their body helps reduce
air resistance when flying, and their muscles are extremely
powerful compared to their body. Bird lungs are also designed so
that when birds breathe they absorb a lot of oxygen, which is
needed to keep the muscles working over long periods of time. Why
are birds' wings covered in feathers? They catch the air and force
it downward when they flap. This creates lift and pushes birds up
in the sky. Airfoils are the human engineered version of bird
wings. Airfoil is the term for the cross-sectional shape of a plane
wing, helicopter blade, or a propeller, rotor, or turbine.
