On the night of July 6, 1943, a plane took off from an Air Force base in England to intercept (截击) German fighters over the English Channel. Piloting the plane was Captain Thomas Nash. Looking westward, Nash saw twelve orange lights in a row, moving at a fantastic rate of speed. An old experienced flyer, he had never seen anything like them. Thinking they might be a new German weapon, he decided to give chase. But when he swung the plane around and headed directly for the lights, they disappeared.

    Captain Nash may have been the first to see such orange lights but he wasn’t the last. His experience was repeated many times by pilots during World WarⅡboth in Europe and the Far East. Pilots in the Korean War also reported seeing the strange lights.

    What were they? No one knows for sure, but there is an interesting theory to account for them. According to this theory, the orange lights are space animals ― animals 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 not visible from earth. They feed partly on the air and partly on energy from sunlight. Being almost pure energy themselves, they can adjust their bodies to glow (发光) at night. During the day they become invisible.

Before World War II, continues the theory, there was little radiated (发射的) energy available on the earth’s surface. Then came the development of rockets, atomic reactors (核反应堆), and hydroelectric plants (水力发电厂). The space creatures are attracted to these sources of energy of food. At night when there is no energy from sunlight, they go down into the lower levels in search of a meal. They may even drift into the range of human eyesight. This explains the fact that they have been sighted regularly from the earth since 1943.

　　On the night of July 6, 1943, a plane took off from an Air Force base in England to intercept(中途拦截) German fighters over the English Channel. Piloting the plane was Captain Thomas Nash. Looking westward, Nash saw twelve orange lights in a row, moving at a fantastic rate of speed. An experienced flyer, he had never seen anything like that. Thinking they might be a new German weapon, he decided to chase(追赶) it. But when he swung the plane around and headed directly for the lights, they vanished(消失).

　　Captain Nash may have been the first to see such orange lights but he wasn't the last. His experience was repeated many times by pilots during World War Ⅱ, both in Europe and the Far East.

　　What were they? No one knows for sure, but there is an interesting theory to account for them. According to this theory, the orange lights are space animals－animals specially adapted to lie 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 not visible from earth. They feed partly on the air and partly on energy from sunlight. Being almost pure energy themselves, they can regulate their bodies to glow at night. During the day they become invisible.

　　Prior to World War Ⅱ, the theory continues, 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 to these sources of energy or food. At night when there is no energy from sunlight, they come down into the lower levels in search of a meal. They may even drift into the range of human eyesight. This explains the fact that they have been sighted periodically from the earth since 1943．
