"[voice over] Since biblical times, man has witnessed and recorded strange manifestations in the sky, and speculated on the possibilities of... visitors from another world. Today from the skies of California... to fields of Kansas... the rice patties of the Orient... the air lanes of the world... come persistent reports of UFOs: unidentified flying objects which we have come to know as flying saucers. In Dayton, Ohio, the Air Intelligence Command gathers and sifts data from all quarters of the globe. Ninety-seven percent of the objects prove on investigation to be of natural origin... but three percent still are listed as unknown. The Air Force is aware of the widely held belief that some of these could be flying saucers from another planet. While there is nothing conclusive in the evidence, the probing and digesting of information about UFOs continues unceasingly. As a result, headquarters of the Hemispheric Defense Command in Colorado Springs issued an order: all military installations are to fire on sight at any flying objects not identifiable. But even as they did so, the military wondered whether their scientific know how and their best weapons would be effective in any battle of...the Earth Vs. the Flying Saucers."

"Narrator: Great scientific advances are oftentimes sudden accomplished facts before most of us are even dimly aware of them. Breathtakingly unexpected, for example, was the searing flash that announced the atomic age. Equally unexpected was the next gigantic stride when Man moved out of his very orbit to a point more than 20 million miles to Earth."

"You better tell them we're in a hurry and to roll up the red tape and put it into a drawer until this thing is over!"
