“almost everyone thought I was crazy.” His JetLev personal transporter relies on an engine and fuel tank (which remain on the water’s surface) to pump H20 into a backpack that then shoots out streams of water to keep your airborne. Top speed is 22MPH, max height is nearly 33 feet, CRAZY, can you afford this???
