ABSTRACT:
A vertical take-off aircraft having a main power plant at the top of the aircraft to provide lift and an additional power plant to force air to travel in a horizontal direction to counteract the rotational force exerted on the main body of the aircraft by the main power plant. The additional power plant is connected to the aircraft such that tilting of the main power plant relative to the main body of the aircraft is able to cause the additional power plant to move relative to the main body of the aircraft.
