JetPack Aviation calls itself the maker of the world's only real jetpack — a jet turbine-powered backpack powerful enough to lift a person into the air, but small enough to fit into the trunk of the car.
As they say on their website:
"We believe a JetPack should be just that — a jet turbine powered backpack that is capable of vertical takeoff and landing (VTOL), is extremely light and small and can easily be carried around by the pilot. It should be powerful enough to lift the pilot quickly to thousands of feet above the ground but small enough to fit into the trunk of a car."
In contrast, most "jetpacks" are actually powered by rockets, streams of water, or other means — not jets.
The company's JB-9 can fly more than 100 miles per hour, can soar above 10,000 feet, and can last 10 minutes, according to Popular Science. The founders of Jetpack Aviation have been working on their product for 40 years, according to the company's website.
