飞去来器最初是澳大利亚土著居民的捕猎工具,它能在飞旋一圈后再飞回投掷者手中,这主要是因为它有像飞机的机翼一样的两“翼”。不过,作为武器它是不往回飞的,因为它的目的就是尽可能快地飞出去击中猎物。正如飞机的机翼一样,飞去来器的上下表面并不一样,它的上表面略微鼓起,而 The Flyder was originally a hunting tool for Australian aboriginal people and it could fly back into the hand of the thrower after flying for a lap, mainly because it had two wings like the wings of an airplane. However, as a weapon, it does not fly back because its purpose is to fly as fast as possible to hit prey. Just like the wing of an airplane, the upper and lower surfaces of the aircraft are not the same, and its upper surface is slightly bulging.
