Rare cloud formation over the Gulf of Mexico. Some people speculate that flying saucers could be the reason for the bizarrely arranged clouds.
But as is often the case, a simple scientific explanation is much more likely. In this case, airplanes are probably the cause. According to the information, medium-high altocumulus clouds consist of very cold liquid water droplets. The air that moves around the wings continues to cool. This sets off a chain reaction: more ice crystals form around the first ice crystals. At some point these become so heavy that they fall from the sky.
