Jet backpack

One big drawback of such backpacks is that if engine fails, you have a
REAL problem.  Human body does not have enough lift for glide, jetpack
will not autorotate. If engine fails, or you run tank dry while you're
still in air, you're hurting, maybe dead.

Another problem.  There is no vertical stability.  Admittedly very small
jets have better spoolup (throttle response), but it can still be a
problem- good throttle response is necessary to get these things to fly 
without pilot being absolute world's hottest pilot.  Touching down
gently is very difficult.
