The Pentagon has released a new batch of declassified UFO files, which includes documents and videos related to unidentified aerial phenomena. The release appears to be part of a larger effort to disclose information on the topic, with some reports suggesting it is the third batch of files, although one outlet claims it is the fourth. The files include records of past sightings, such as "green fireball" incidents, and a CIA memo that admits to destroying records and providing evasive answers in the past.
