An American company says it has developed the world’s first true jetpack for personal flight. California-based JetPack Aviation recently demonstrated its flying device to the public. It looks simple enough that almost anyone could use it to fly around. The company’s JB-10 flying machine is built like a backpack. It looks similar to the bags people use to carry anything from food to books on their back. Jetpack Aviation’s device is powered by two jet engines. The engines can operate on either airplane fuel or automobile diesel fuel.
