Some people are calling it a hoax but it looks all too real. Franky Zapata, the remarkable Fenchman who invented the Hoverboard, has flown the Flyboard Air. A few days ago, somewhere near Marseilles, he travelled the sky in sci-fi fashion. It was the triumph of nearly two years work by Zapata. The rider carries a backpack of fuel and a remote control to manage the four jet engines that keep him a loft. Here’s a caution. It is easier to fall off of than a Hoverboard and take months to learn how to fly.
