Documents / FOIA release
This CIA release, dated 2013-06-24, is an English translation of "UFOs: What Are They?", an article by F. Yu. Zigel' printed in the Soviet magazine Smena in February 1967. Zigel' reviews reported sightings, including the Mantell crash, Clyde Tombaugh's 1949 observation, Antarctic station reports and radar detections. He then weighs five explanations: hoaxes, optical illusions, secret aircraft, an unknown natural phenomenon and craft from other planets. He concludes that no hypothesis is final and that the phenomenon calls for careful scientific study.

color changes, extending over several minutes, were accompanied by radio interference, though no magnetic storm was in process at the time. In the same year UFO reports were received from England, France, Portugal and other countries. In the summer of 1965 above the airport of Canberra there appeared a soaring object which duty personnel at the field in the control tower saw perfectly clearly. It hung over the airport for about 40 minutes and disappeared only when a plane was sent up to identify it. Near Canberra, where is located the Tinbinbillskiy space tracking station, a mysterious object was noted not long before the station began receiving signals from Mariner 4. But with the appearance of the object unusual difficulties arose in the reception of the signals. It has been noted also that UFOs are most often observed in areas near the poles, the cosmic space over which is free from radiation belts. For two decades UFOs have been observed not only visually but also on radar screens. In 1965, according to a United Press report, radar sets in Oklahoma recorded on the evening of 1 August four unidentified objects flying at great height. They passed over into the atmosphere over the states of Kansas and Colorado. In Moscow in June 1965 an international colloquium was held on the microstructure of the atmosphere at which there was discussion of the nature of "angel-echo"--strange objects seen on radar screens. These are regularly observed by Soviet scientists working at the Central Aerological Observatory near Moscow. According to the report of Cand Phys-Math Sciences A. Gorelik, UFOs have been recorded on radar screens not only in the USSR but also at stations in the US, Australia, India, and Japan. It has been established that the mysterious flying objects cannot be insects, plant seeds, flights of birds, which sometimes show up on radar. They frequently moved against the wind and were observed in places where they are no birds or insects. The nature of these objects remains unknown to this day. The reader is probably already wearied by the listing of facts and is waiting for generalizations, explanations, and conclusions. Let us attempt to provide them. In the last two decades there have been many thousands of factually irrefutable reported sightings of UFOs. Reports have come twenty countries and the "UFO phenomenon" must today be considered a worldwide one. Evidently this circumstance was one of the reasons why recently, for example in the US, as
