Re: Do not want.
By virtue of most civil aircraft being winged objects or powered parachutes you are correct.
That said, A helicopter without power doesn't make for a particularly comfortable landing, nor does a powered parachute when it's parachute knots up, regardless of power.
The 'jetpack' is sold with an optional BRS (Ballistic [Parachute] Recovery System) for a survivable vertical landing without power.
