*U* UFO Database

Compiled and developed by Larry Hatch

As of January, 2001 *U* holds over 17,750 carefully filtered UFO events distilled from hundreds of books, major journals, catalogs, downloads and other sources. "Junk" sightings ( night-lights, fireballs, discovered hoaxes etc.) are systematically filtered out. Otherwise, *U* would hold several times the present number of listings. Scope is world-wide, for all dates from antiquity to the present.

National UFO Reporting Center

The National UFO Reporting Center, located in Seattle, WA, was founded in 1974 by noted UFO investigator Robert J. Gribble. The Center's primary function over the past two decades has been to receive, record, and to the greatest degree possible, corroborate and document reports from individuals who have been witness to unusual, possibly UFO-related events. The principal means used by the Center to receive sighting reports is its telephone hotline, which has operated almost continuously since 1974. During that period, the hotline has processed many tens of thousands of calls, and the Center has distributed its information to thousands of individuals. The hotline is well known by law enforcement agencies, FAA ARTCC's and flight service stations, National Weather Services offices, military facilities, NASA, and many 911 emergency dispatch centers all across the United States and in many parts of Canada. Those entities routinely direct the calls they receive regarding possible UFO sightings to the Center.
