UFO

Many people say they have seen UFOs. Here is one famous story. It is called the Roswell Incident and it happened in the US in 1947.

Person A (name not given): My wife and I were sitting outside because it was a warm night. Suddenly we saw something very bright flying through the sky.

Person B (William Brazel, a farmer): I found some pieces of strange metal on my farm. I called the army. Major Marcel came and collected the pieces. He told me not to talk to anyone about this.

Person C (Major Marcel): I went and collected the pieces. I gave them to an army expert. He said the pieces came from a weather balloon. However, since I have not seen this kind of metal before, I think this was a lie.

Person D (name not given): My parents and I were in the countryside. Suddenly we saw a silver spaceship on the side of the hill. There were the bodies of three aliens lying on the grass. Then some soldiers came and told us to leave.

So what is the truth?

• Perhaps some or all of the people lied.

• Perhaps a US rocket crashed and people thought it had come from space.

• Perhaps an alien spaceship really crashed in Roswell.
