Ponca City, We love you writes "Jet packs have been around for half a century, but there's always been one problem: they run out of fuel in around 30 seconds. Now a German company has taken the standard jet pack design, run a fat yellow hose out the back, and connected it to a small unmanned boat that houses an engine, pump, and fuel tank and sends pressurized water up the hose, where it's shot out by two nozzles just behind the wearer's shoulders. Called the JetLev-Flyer, the design purportedly can reach a height of 15 meters, a speed of 72 kph, and a range of 300 kilometers based on four hours of flying time. A digital fly-by-wire system is used to control the throttle. Future designs may achieve higher altitudes, higher top speeds, and extended range, and even travel below the water's surface. The American manufacturers claim it is 'amazingly easy to learn and operate' and they're taking orders now at $130,000 each."
