摘要： An aerial toy is disclosed which can be launched to sail outwardly away from the point of launching and subsequently reverse its flight and return to the point of launching, and which can further be thrown to traverse a distance between two points, such as in a game of throw and catch. The aerial toy has four equiangularly spaced blades which are joined at a common central body portion. Each blade terminates in a vane which is angled relative to the blade, with the tips of each vane attached to an outer circumferential ring.
