Airships

An airship is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Unlike fixed-wing aircraft or helicopters, airships are lighter-than-air (LTA) typically using helium to stay aloft. Airships are equipped with engines for power generation whereas aerostats are tethered to the ground, by a cable that tends to provide power.
