IT’S ABOUT TIME: This could be the jetpack we’ve all been dreaming about. “A real jetpack needs to be small and light enough that you can put it on and walk around. It needs to be safe enough and reliable enough (in principle if not in practice) for regular use. And most importantly, it needs to be able to take off vertically, fly for a useful distance and time, and land vertically without turning its passenger into goo. Jetpack Aviation’s JB-9 does all of these things.”
