This is a United States Air Force fact sheet from the Office of Public Affairs, Secretary of the Air Force. It covers the Air Force's UFO investigations from 1948 to 1969 under Projects Sign, Grudge and Blue Book: 12,618 sightings were investigated, and 701 remain unexplained. It records that Blue Book ended on December 17, 1969, and that its conclusions found no threat to national security and no evidence of extraterrestrial vehicles. It also includes yearly sighting totals and a list of private UFO study organizations.
In 1977, President Carter asked the National A~ronautics and Space Administration (NASA) to look into the--possibility of resuming UFO investigations. After studying all the facts available, NASA decided that nothing would be gained by further investigation. The Air Force agrees with that decision. If, how~ver, firm evidence is found justifying further investigation, an appropriate agency will be directed to undertake the effort.

There are a number of universities and professional scientific organizations such as the American Association for the Advancement of Science, which have considered UFO phenomena during periodic meetings and seminars. In addition, a list of private organizations interested in aerial phenomena may be found in Gale's Encyclopedia of Association~. Such timely review of the situation by private groups insures that sound evidence will not be overlooked by the scientific community.
