Context paragraphs:
Sightings (TV series): Sightings is an American paranormal and news television series that originally aired in the 1990s.  The program began as a special titled "The UFO Report: Sightings" on October 18, 1991, as well as eventual follow up reports, "Ghost Report" and the "Psychic Experience".  The original Concept Creator and Supervising Producer of that hour special produced by Paramount for Fox TV was Linda Moulton Howe, an Emmy Award-winning TV producer and documentary filmmaker of TV specials about science and the environment.  One of her Emmy Award-winning broadcasts was "A Strange Harvest" (KMGH-TV in May 1980), about the worldwide animal-mutilation mystery linked by law enforcement to extraterrestrial biological entities.

Identification studies of UFOs: Identifying unidentified flying objects is a difficult task due to the normally poor quality of the evidence provided by those who report sighting the objects.  Nevertheless, most officially investigated UFO sightings, such as from the U.S. Air Force's Project Blue Book, have been identified as being due to honest misidentifications of natural phenomena, aircraft, or other prosaic explanations.  In early U.S. Air Force attempts to explain UFO sightings, unexplained sightings routinely numbered over one in five reports.  However, in early 1953, right after the CIA's Robertson Panel, percentages of unexplained sightings dropped precipitously, usually being only a few percent in any given year.  When Project Blue Book closed down in 1970, only 6% of all cases were classified as being truly unidentified.
