World UFO Day is celebrated annually on July 2 to bring awareness to mysterious objects in the sky. It may raise more than a few eyebrows, but don’t be so quick to dismiss this annual event: Last year, reports revealed that the United States government had run a secret program to investigate unidentified flying objects for years.

The partially declassified program to investigate UFOs, called the Advanced Aerospace Threat Identification Program (AATIP), existed from at least 2007-2012 but may still be active in some way, shape, or form. The Central Intelligence Agency’s website lists pages and pages of information on UFO reports from the 1940s through the early 1990s alone.

Remember, however, that unidentified flying objects still amount to just that: objects we can’t name but could have any number of non-extraterrestrial origins (sorry, alien stans). In honor of the occasion, Inverse dug through reports of unidentified flying objects from the Pentagon and the CIA to bring to light three of the weirdest discoveries.
