On Saturday, Franky Zapata took his prototype Flyboard Air hoverboard for a rather impressive flight, three miles on the French coast. It's based on Zapata's previous water-powered hoverboard. When the first short flight video went up last month, The Verge interviewed Zapata: So there’s three parts to this, right? The board, a fuel tank, and a remote? Franky Zapata: Yes, the thing I have on my back is like a Camelbak but it’s full of kerosene.
