Control jets are small orifices in the top/bottom and/or sides of the object to be controlled, through which gas can be ejected. This gas may be tapped from the main engine or generated separately from compressed gas in bottles or by burning fuel. If mounted in the front of the vehicle, a gas jet blowing out the left of the nose will push the nose, and therefore the object, to the right. If mounted behind the center of gravity of the object the opposite effect will occur - a gas jet on the left side will turn the object to the left. Varying the amount of gas exiting the jet will control the amount of force and therefore the rate of turn.
