                    Jet fleets fly in V formation.
                    There is a very important reason for
                    this. Flying in formation, each plane
                    causes a vortex diagonal to its wings.
                    This means that the plane behind is
                    subjected to less air drag and needs
                    to use less power, resulting in a 20%
                    saving of fuel.
                    Surprisingly, migrating birds also ha-
                    ve this knowledge. Geese, ducks and
                    swans also use this V formation in
                    flight.
                    Each bird benefits from the field ca-
                    used by the bird in front. Flying in le-
                    ading position is tiring, and the birds
                    take turns at this duty.
                    And here is the big secret: Flight in V
                    formation uses less fuel, a fact disco-
                    vered by aerodynamic engineers.
                    But how do migratory birds know
                    this scientific calculation?
                    How do they organize themselves in
                    a disciplined fashion?
                    How does each bird know its place in
                    the course of flight?
                    Why do birds make sacrifices for
                    each other by taking turns in leading
                    position?
                    These questions lead us back once
                    more to the truth of creation.
                    God creates all species with perfect
                    bodies and inspires them to use their
                    features in the best way.
