AATIP / TTSA — Pentagon Program Disclosure
On December 16, 2017, the New York Times published a front-page story revealing the existence of the Advanced Aerospace Threat Identification Program (AATIP), a classified $22 million Pentagon UAP investigation program that ran 2007–2012. The story included the first officially released DoD UAP videos (Nimitz and Gimbal) and an interview with program director Luis Elizondo, who resigned citing internal obstruction. The disclosure marked the beginning of the modern era of US government UAP transparency.
