If you ever seen an UFO with a plasma propulsion supporting it,
it is likely that the plasma ball is spinning in a up-down direction instead of horizontally. This direction creates lifts that provide for anti-gravity.
In a similar way, a missile that proposes to generate lift and velocity with a ball of fire, is best also spinning the ball of fire in a plane parallel to its direction of travel. Changing the axis of this plane of spin, changes the direction of travel. Vectoring.
It is the velocity along a circular path of the plasma in the interior of the containment of the fire ball that is vs, the spin velocity developed in the previous posts "Spinning Plasma" and "Spinning Plasma" dated 05 and 04 Jul 2016, respectively.
Unlike a jet engine, the spinning dragon ball is contained not open ended. No hot material is lost from the fire ball.
KO!
