飞碟不只是出现在科幻书或者未知探秘里,现在,世界有不少国家和地区的科学家们正在公开或秘密地研制属于人类的飞碟。萌芽出现在美国美国是世界上开展人造飞碟研制工作最早的国家。1976年,在美国出版的一份《现代飞行器》报纸上,刊登了一张圆盘状飞行物的照片,飞行器的周围,离子气流发出UFO特有光彩。20世纪末期,美国太空总署的科学家研究制造一种使用空气作燃料的新式人造飞碟,从而把发射太空船的成本降低至1/1000,同时飞行速度可大幅增加,飞越半个地球只需45分钟,不到6小时就可从地球飞到月球。
UFO not only appears in the science fiction book or unknown mystery, and now, many countries in the world scientists are openly or secretly developed belonging to human UFO. Emergence in the United States The United States is the earliest country in developing artificial flying saucer in the world. In 1976, in a newspaper published in the United States, “Modern Aircraft” published a photograph of a disc-shaped flying object around which the ionized air stream emitted UFO’s unique light. In the late twentieth century, NASA scientists studied the creation of a new artificial flying saucer that uses air as the fuel, reducing the cost of launching a spacecraft to 1/1000 while dramatically increasing the speed of flight and flying over half of the Earth at a mere 45 Minutes, less than 6 hours can fly from the Earth to the moon.
