A moored balloon is an inflated fabric structure, often shaped like an airship and usually filled with helium that is restrained by a cable attached to the ground or a vehicle. Moored balloons differ from airships and free balloons in that airships and free balloons are both free flying.
Moored balloons come in two forms:
- 1) Traditional sausage shaped (i.e. blimp shaped) with fins to stabilise them, but relying upon helium alone for lift
- 2) Simple round balloons relying on helium alone, but without stabilisation, which sometimes are used to make passengers fly, or support advertisement, like the aerophile balloons
