Some people think that they are spaceships from other planets. Doctors32that perhaps they are only a weakness of the eyes. It is possible that they are our own planes33very high. Or are they birds with the sun’s light on them?

People have36photos of flying saucers and of these beings. We have seen the photos, but sometimes the people had to take them in a37. Children have seen flying saucers, and even dogs have seen them. Perhaps we do not think that the38of children, or dogs are important. But school-teachers have39seen them and Air Force officers and40policemen. Must we not listen to these people?
