Despite the satisfactory scientific explanation that the formations are what are known as lenticular clouds, which usually warn of storms, die-hard ‘ufologists’ believe they are in fact masking alien visits.

Lenticular clouds have been behind alleged UFO sightings around the world, from Indonesia to Florida.
