Model rocketry is a popular hobby in which (disposable or reusable) cylindrical rocket engines are placed in the back end of the miniature rockets. The rockets are launched in open fields by igniting these engines and the rockets (and usually the engines) subsequently recovered after soft landings. At flight apogee parachutes or other recovery devices are ejected forward from the fuselage of the rocket by explosive charges built into the engines, allowing a soft landing. Gases from the last of the engine fuel ignite these charges, which are stored in the forward compartment of the engine.
