Watch the world’s largest aircraft in the video above.
Could the airship be finally ready for a comeback?
In 2013, the Aeros Corporation, based near San Diego, demonstrated a tethered flight of Dragon Dream – an airship measuring 90m (295ft) long and 27m wide.
As big as this airship is, it is still only small prototype – the final design could be more than 169m long and be able to carry a cargo of 66 tonnes.
In the video above, BBC Click's Spencer Kelly finds out what it takes to build an airship on this humungous scale.
