Billed as the world's first flying motorcycle, this concept speeder could change personal transportation forever. 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.
