Government program
Advanced Aerospace Threat Identification Program (AATIP)
A small Defense Intelligence Agency program (~$22M) studying UAP, public knowledge of which became the seed of the 2017 Disclosure era.
Established in 2007 within the DIA at the urging of Senator Harry Reid, with funding largely flowing to Robert Bigelow's Bigelow Aerospace Advanced Space Studies (BAASS). Luis Elizondo says he ran AATIP after 2010. Whether AATIP and the related AAWSAP contract are the same program is disputed by the DoD's public statements; Elizondo and supporters say they were continuous.
