Jetpack Aviation created the speeder and says it will be powered by four jet engines fueled with kerosene, diesel, or Jet-A-fuel. They’re planning two versions — one that is ultralight and will fly 60mph with no pilot’s license required, and an experimental version that can fly over 150mph but will require a formal license to operate. The company says the craft will have up to 30 minutes of flight time, with a flight ceiling of 15,000 feet. They’ve already built an operating, 1/3 scale prototype which is undergoing test flights, with plans for a full version within 14 months.
