An axe kick is so dangerous... because of being on the ground affected by gravity
It is a huge wind up, and straight down (in the direction of gravity) onto vital areas of continued consciousness.

If you add controlled flight, the type that ignores gravity, then these types of maneuvers would just be classified under hay-makers. Long wind up maneuvers.

I tried to talk to the Air Force about such planes... they said they were too complicated.
