This video shows a giant jet engines in action that are so powerfull B-1 Bomber and F-16 Fighting Falcon Full Afterburner Engine Test.
An afterburner (or a reheat) is a component present on some jet engines, mostly those used on military supersonic aircraft. Its purpose is to provide an increase in thrust, usually for supersonic flight, takeoff and for combat situations. Afterburning is achieved by injecting additional fuel into the jet pipe downstream of (i.e. after) the turbine. Afterburning significantly increases thrust at the cost of very high fuel consumption and decreased fuel efficiency, limiting its practical use to short bursts.
