The Advanced Aviation Threat Identification Program (AATIP) was a secret investigatory effort funded by the United States government to study unidentified flying objects, but it was not classified. It was first made public on 16 December 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.
