　　Early this year, Captain Startup was flying a plane over New Zealand. There; was a television camera crew on board. Suddenly, out in the night sky, a bright ball came into sight. Everyone on board saw it and everyone thought, “UFO”. The camera crew went into action and started filming. That week, people all over the world saw the film of this mysterious light on their television screens.

　　But what was it? Was it a spaceship full of visitors from another planet? The Captain and the film crew believed it was. Other observers had many different explanations. Some say it was Venus. Some say it was just a trick of light.

　　The people on the plane were not the only ones who saw the “UFO”. An air traffic controller also saw it on his radar (雷达) screen. When a reporter asked him if he believed in UFOs, he said, “I don't know what they are but I've got an open mind on them.”

　　Most astronomers (天文学家) now believe that what these people saw was almost certainly the planet Venus. At that time of the year it is very bright and easy to see. And from a moving plane it can appear to be moving fast. So far there is no proof that UFOs or spaceships from other planets do exist.

    Most astronomers now believe that what these people saw was almost certainly the planet Venus．At that time of year it is very bright and easy to see．And from a moving aeroplane it can appear to be moving fast．So far there is no proof that UFOs or spaceships from other planets do exist．In 6 years government investigators of UFOs investigated 1,631 sightings or occasions when people say they saw a UFO ．Ninety percent of these turned out to have simple explanation.

    However, it’s good idea to keep an open mind, like the air traffic controller．Scientists in the USA are trying to persuade their government to help them study UFOs．They want two million dollars to spend on detecting radio messages from outer space．And a British politician wants governments to cooperate internationally on reporting and investigating sightings of UFOs.

    After all, it is quite possible that there is life out there in the universe．And if something is alive, it is quite possible that it may come to visit US.
