The Guinness World Records says that Catalina Alexandru Duru just pulled off the farthest flight ever traveled on a real life hoverboard: 905 feet and 2 inches. You can see him rise up 16 feet in the air on the hoverboard and then start cruising through the air over a lake with nothing but invisible underneath him in the video below.
The hoverboard Duru uses is more like a super powerful quadcopter-type hoverboard and not a hoverboard in the Back to the Future sense but it’s still pretty awesome. And also, the added bonus of not using BTTF-style? This one works over water.
