“The jetpack is made from carbon fiber, with a touch of kevlar in the rotors, and generates 600 pounds of thrust. Because the center of gravity is below the ‘center of thrust’ (a notional point between the engines), it is self-righting: If the pilot lets go of the controls, he hovers steadily in one spot.” Where is my jetpack? Ah, it’s right here, for the paltry sum of $75,000-$90,000. [You can see it in action here.]
