They claim to be the world's only true Jet-pack.
in their words: "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. Meet the JB-9 JetPack."
"Our R&D plan includes longer endurance but trust me, when you fly at more than 100 mph for 10 minutes + you will know you're flying the world's only jetpack. One day we will be in a position to sell them and maybe sooner than people think but we want to make sure we have all the training systems etc right first."
