Have you ever wondered why a boomerang flies and returns like it does?
A boomerang is a traditional Indigenous implement with certain aerodynamic properties, traditionally made of wood
Returning boomerangs fly and are examples of the earliest heavier-than-air human-made flight. A returning boomerang has two or more air foil wings arranged so that the spinning creates unbalanced aerodynamic forces that curve its path so that it travels in an ellipse returning to its point of origin when thrown correctly.
A returning boomerang is used purely to scare or herd the prey in the direction on the hunters, whilst a properly made hunting boomerang actually flies straight and level on its path towards the target, out to a range of around 100 metres.
