Blade-mounted rockets apparently allow for the deletion of the normally necessary tail-rotor. According to TAM, the lack of the tail-rotor makes this backpack-mounted helicopter-of-death safer than the more common types you see flying in the sky. Call us crazy, but regardless of how safe the manufacturer is suggesting that his proposed one-man flying-machine may be, we can't see too many people jumping at the idea of strapping rocket fuel to their backs and flying to work. Sure does look fun, though!
