AATIP meaning in Governmental ?

The Advanced Aerospace Threat Identification Program (AATIP) was an unclassified but unpublicized investigatory effort funded by the United States Government to study unidentified flying objects (UFOs) or unexplained aerial phenomena (UAP). The program was first made public on December 16, 2017. The program began in 2007, with funding of $22 million over the five years until the available appropriations were ended in 2012. The program began in the U.S. Defense Intelligence Agency.

According to the Department of Defense, the AATIP ended in 2012 after five years, however reporting suggested that U.S. government programs to investigate UFOs continued. This was confirmed in June 2020 with the acknowledgement of a similar military program, the unclassified but previously-unreported Unidentified Aerial Phenomenon Task Force.

A group including Luis Elizondo, who was the AATIP program director, went on to work to a public-benefit corporation named To The Stars Academy of Arts & Science in 2017.
