Declassified FBI and Air Force records from 1950 show that military intelligence agencies were actively investigating unexplained 'green fireball' phenomena in New Mexico, holding multi-agency conferences at Los Alamos and funding scientific studies, with no explanation ever found.
Declassified FBI files show that in 1960, Joseph Perry of Grand Blanc, Michigan, reported photographs of an unidentified flying object silhouetted against the moon. The FBI stated it was not investigating the matter and turned the photos over to the Air Force, while also correcting a newspaper report that suggested otherwise.
Declassified FBI files from 1947 detail the investigation into a B-25 crash at Kelso, Washington, that sparked rumors of flying disc fragments and sabotage. The FBI concluded the story was a hoax, originating from rock formations found on Maury Island.
Recently released NASA emails show that as of early 2021, the agency had no funded investigations into Unidentified Aerial Phenomena, despite internal queries and coordination with the UAP Task Force.
A declassified DIA reference document from 2010, produced under the Advanced Aerospace Weapon System Applications Program, compares the innovative potential of independent 'maverick' inventors with that of corporate researchers, focusing on unconventional energy and propulsion systems, including free-energy and antigravity concepts.
A declassified Defense Intelligence Agency report from 2010, produced under the Advanced Aerospace Weapon System Applications program, reviews the physics and feasibility of extracting energy from the quantum vacuum, including the Casimir effect and zero-point field, for potential space power and propulsion applications.
A March 13, 2020 letter from the Department of the Navy's Office of the Judge Advocate General denied a FOIA appeal seeking Navy records related to AATIP, stating no responsive records exist and rejecting claims about Navy involvement in the program.
A declassified Defense Intelligence Agency report from 2010 surveys the field of BioMEMS, including brain-implanted electrodes that can detect a person's intent to move, potentially enabling thought-controlled prosthetics for paralyzed individuals.
A declassified Defense Intelligence Reference Document from 2011 details theoretical concepts for negative mass propulsion, suggesting that negative masses could be mined from the Moon's gravitational well to enable interstellar travel.
A 2010 Defense Intelligence Agency reference document, produced under the Advanced Aerospace Weapon System Applications program, speculates on cockpit designs for future spacecraft capable of faster-than-light travel and control over gravitational and inertial forces, including concepts like the Alcubierre warp drive.
A declassified DIA reference document from 2010 surveys the history of attempts to manipulate gravity using superconductors, including the controversial Podkletnov experiments and theoretical work by Li and Torr. The document was produced under the Advanced Aerospace Weapon System Applications (AAWSA) Program.
A declassified DIA status report from August 2009 shows that Bigelow Aerospace Advanced Space Studies (BAASS) was in full compliance with a contract to produce research reports on topics including metamaterials and invisibility, wormholes in spacetime, and antigravity studies. The DIA recommended exercising option year 1 with $12 million in funding, and noted the program would likely become a Special Access Program by June 2010.
