AATIP

THE PROGRAM

AATIP ran from roughly 2007 to 2012 as a Defense Intelligence Agency effort to investigate military reports of unexplained aerial objects and the science that might explain them. It was funded through a roughly $22 million congressional earmark championed by Senate Majority Leader Harry Reid, and much of that money flowed to Bigelow Aerospace — the company of Reid's associate Robert Bigelow — which contracted researchers to study cases and possible advanced-aerospace technologies.

ELIZONDO AND THE 2017 REVEAL

Luis Elizondo has said he led AATIP from inside the Pentagon and resigned in 2017 partly in protest at the secrecy around it. In December 2017, The New York Times revealed the program's existence and published three Navy infrared videos alongside the story. The Department of Defense's account of who exactly ran AATIP, and when, has been less than clear — but the program's reality is not in dispute, and the 2017 story is the hinge on which modern disclosure turns.

FROM AATIP TO PURSUE

AATIP was the seed. Its public exposure led to a string of successor efforts — the UAP Task Force, then AARO — and ultimately to the PURSUE program now publishing declassified files. The arc from a buried Pentagon line-item to a public government portal is the story of the whole era, and Umbra is where the record that arc produced can be read.
