Well, not exactly, but 'jet pack' sounds better than 'ducted fan pack'. If there is a cooler toy to be had than this, I would sure like to know what it is.
My first question was how much flight time you get. It carries 30 minutes max fuel, so you would want to keep it down to 20 minutes to be safe. But that limitation is only due to the five gallon fuel tank required by FAA ultralight regs. The device has not yet been approved by the FAA. It has a safety parachute built in. Apparently the danger with this thing is rate of descent. Come down too fast, and you are going to go 'splat!'
