The current iteration of the Martin design uses a 2,400 hp gas engine to drive two ducted fans for up to 30 minutes of flight time at speeds of up to 45 mph and heights of up to 1,000 meters. The pack's body is made of aluminum and carbon fiber.
With plans to roll out a first responders' version of the jetpack starting at the end of this year, the commercial version is set to follow. Expect to see it retail at around $150,000. Come next year, you might look up and finally see people zipping around fulfilling Thunderball fantasies.
