Solar Airships
These can look extremely impressive and very unusual indeed. Solar Airships typically appear long cylindrical/cigar shaped objects. They are made from a light material and launched on a hot sunny day. When the air inside them heats up they lift up into the sky. They are commercially available and are usually black in colour, as this is the colour which soaks up the most heat. However they can come in a variety of other colours such as silver. It is possible to make home-made solar airships by tying bin bags together.
Solar airships are typically very large in size. They are also usually tethered, however at a distance this
tether would of course not be visible to the naked eye. They can also occasionally break free from this
tether and drift across the sky. While airbourne, they are often seen to rotate or hang still at a
strange angle, even completely vertical. They are extremely light weight and
flimsy, so if caught in air currents can bend and curl around, which can give
the appearance of a living snake-like creature. These
will often appear to change shape as they are buffeted by the wind.
As they are usually launched on bright sunny days, the sunlight can sometimes reflect off their smooth surface, giving the impression of twinkling flashing lights of different colours.
