Franky Zapata stands on his jet-powered "flyboard" as he took off from Sangatte, northern France, on August 4, 2019, in an attempt to fly across the 35-kilometer Channel crossing in 20 minutes, while keeping an average speed of 140 kilometers an hour at a height of 50-65 feet above the sea. The Frenchman, who has spent years developing a jet-powered hoverboard, tried to zoom across the English Channel on August 4, after a first attempt last month was cut short when a botched refueling attempt sent him into the water.
