Agencies, organisations and databases that document or classify UFO/UAP reports. This is the source of a report, not its content.

Do not confuse Authority with Classification. Authority is where a report came from (NUFORC, AARO, FAA, MUFON); Classification is what kind of report it is (Civilian, Military, Historical). They are separate filters on UFO/UAP Reports because a military sighting can be reported to a civilian database and vice versa.
