Ever wonder what a jetpack is good for, besides fulfilling dreams and fighting Nazis? Well, Martin wants you to know there are, in fact, practical applications for its $86,000 personal propulsion system . According to the aviation company everyone from emergency responders to search and rescue teams to military personnel could find a place for the dual-engine craft in their arsenal of tools. Sure, we could see how their ability to get in and out where the size of a helicopter or plane might be prohibitive would prove handy, but their high cost and limited carrying capacity make them a tough sell. That doesn't mean we don't enjoy seeing the (poorly) rendered vision of our future filled with jetpacks in the video after the break. Come to think of it, we could see this coming in handy for our CES coverage... excuse us, we need to make some phone calls.
