In one year there are over 1000 sightings of UFOs called into the police. Most of the people who call in UFO sightings are either drunk or want to be on TV and are faking it. Most of the other sightings of a UFO are flashes of light up in the sky which are satellites. The rest of the sightings are usually weather balloons.
Most people think that they are seeing a UFO when it is really just a weather balloon. A weather balloon is sent up into the troposphere to measure wind speed humidity, and atmosphere pressure. The information is then sent back to a weather station. A weather balloon is inflated helium to a volume of 25.5 cubic feet.
Satellites are most commonly mistaken for a UFO. Most people think that a satellite is a UFO because a satellite flashes and looks distinctive. A satellite flashes because it has a solar panel to attract energy from the sun and the light reflects off the sun making a flash. Some satellites have a flashing light to show it is a satellite or is still working.
A lighting rod is a still metal rod at the top of a building. If there was a severe thunderstorm and lighting struck a building then there would be a high chance of a fire in the building and damage to electronics. If lighting strikes the lighting rod then the rod sends the lighting down a wire into the ground hurting no one and there are no fires.
A wind sock does not look like a sock. It is shaped more like a sideways cone. A wind sock is used to see the direction and the speed of the wind. A wind sock is attached to a long pole with string and has a big hole in the front. If it is windy then the wind sock will fly horizontally and in the direction of the wind.
