In 1947 a pilot of a small aeroplane saw rune strange objects in the sky over
Washington, the USA. He said that they looked like saucers. Newspapers printed
his story under the headline" Flying Saucers".
Since then, all over the world, people have reported similar strange flying objects.
No one knows what they are or where they come from. Some people say that they
do not exist, but many others say that they have seen them. Usually people on the
ground have seen them but not always. Airline pilots also have reported seeing them
and so have astronauts-the men who fly in spaceships.
Perhaps some people saw them only in their imagination or illusion(幻觉). Perhaps
some people made a mistake. But airline pilots and astronauts do not usually make
mistakes of this kind. Captain Ed Mitchell, the sixth man to walk on the moon, said in
1974 that he believed that some" flying sancers (飞碟) " were real. Many other people
now believe that these strange flying objects are visiting the earth from other worlds in
space. "They have come to greet us," they say.
The American government tried to find out more about these objects. It listened to
a great many people who said they had seen them. But the Govemment Committee
could not decide on what the objects were.It called them UFO, which is short for
"unidentified flying object".
Some even say they have seen people in the flying Saucers!In 1964,a driver of a
police car in new Mexico saw a UFO landing a mile away. When he reached it, there
were two small figures standing near it. They looked like little men. When he reported
on his radio, they got inside the object and flew away.
In 1973 two men were out fishing in Mississippi River. They say they saw a UFO
shaped like an egg. There were three creatures like men but their skins were silver in
colour. They had no eyes, and their mouths were just slits(裂缝) . Their noses and ears
were pointed(尖的).They made the fishermen get inside the UFO for a while. Then the
creatures photographed them and took them to the place where they had been fishing.
There are many other similar stories. Some are probably untrue but some may be
true. No one knows.
