The William Mark Corporation (WMC) was founded in 1991 when Mark Forti invented its first flying toy: the X-zylo flying gyroscope. A junior at Baylor University, Mark should have been doing his marketing homework, but instead he was playing around with different flying wings and other airfoils when he stumbled on a cylindrical wing that flew unusually well when spun.
