People can now strap on their own jet-powered backpacks and blast off into the sky—if they have $250,000 to spare, that is. That’s the hefty price tag for the new JB10 jetpack being sold by California-based company JetPack Aviation.

Two jet engines power the JB10. A person uses one hand to control the pack’s throttle—a device that increases or decreases the flow of fuel to the engines. The wearer’s other hand controls the direction the jetpack moves. The pack can reach speeds of up to 100 kilometers (60 miles) per hour and carries enough fuel for a 10-minute flight, says David Mayman, a pilot and CEO of JetPack Aviation. He and lead designer Nelson Tyler have been working on the device for more than a decade.

People who buy the pack can’t take flight until they visit the company’s training facility. There, they’ll learn how to operate the jetpack safely.
