Giving boomerangs consist of 2, or even even other arms or wings, connected at an angle. To each one wing is shaped as an airfoil, air travels faster terminated 1 surface of an aerofoil than a more, when it follows a yearn path, so creating lift, ahanker what is roughly a plane which intersects the surface at a close perfect angle along the long axis of the wing.

These wings come placed then that a lift created by every wing opposes a lift of a more, however at an angle such that a flight pattern is constantly shifted when the forces of lift, drag, speed, rotational inertia etc. 'attempt' to email equilibrium, understand Boomerang engineer.

This is what makes a boomerang 'link to gracefully to the pitcher, fluttering to the prevent around his hand'... after thrown aright. This is too what makes a boomerang 'rocket straight higher into a air prior to plunging to its tattered day of reckoning'... while thrown incorrectly.
