On the night of May 7, 1942, a plane took off from an Air Force base in England to stop Germa fighters over the English Channel. Pilot of the plane was Captain Thomas Nash. Looking eastward, Nash saw twelve orange lights in a row , moving at a fantastic rate of speed. As a sophisticated flyer, he had never seen anything like them. Thinking that they might be a new German weapon, he decided to chase them. But when he swung the plane around and headed directly for the lights, they vanished.
Captain Nash may have been the first to see such orange lights but he wasn’ t the last. His experience was repeated several times by pilots during World WarⅡin Europe and the Far East. What were they? No one knows for sure, but there is an interesting theory to explain them. According to this theory, the orange lights are space animalsanimals specially adapted to life in the upper atmosphere just as some creatures are adapted to life at the bottom of the sea. These space animals, the theory says, live so far up in the atmosphere that they are invisibl from earth. They feed in part on the air and partly on energy from sunlight. Being almost pure energy themselves , they can adjust their bodies to glow at night. During the day they become invisible.
Before World War Ⅱ, continues the theory, there was little radiated energy available on the earth’ s surface. Then came the development of rockets, atomic reactors, and hydroelectric plants The space creatures are attracted by these sources of energy. At night when no energy emitted from sunlight, they go down into the lower levels to search a meal. They may even drift into the scope of human eyesight. This explains the fact that they have been sighted periodically from the earth since 1942.
The space animal theory would seem to indicate that_______.
