London (CNN) — The world's largest aircraft has been retired after six test flights, as its developers prepare to build a new, commercial model to take to the skies in the early 2020s. Hybrid Air Vehicles will now begin work on the production version of the prototype, having secured approved from the UK's Civil Aviation Authority (CAA). Airlander 10, a spectacularly huge, helium-pumped aircraft, is unveiled fully assembled for the first time, in a giant aviation hangar near London. The company also says its production model will "rethink the skies," and is aiming for the aircraft to be low-carbon. The new model will be of a similar size to the prototype, though exact dimensions are yet to be confirmed.
