Short answer: The Pentagon’s All-domain Anomaly Resolution Office (AARO) said in its March 2024 historical report that it found no evidence supporting interviewees’ claims of a U.S. government program reverse-engineering extraterrestrial technology. AARO said it had disproved most of the claims it reviewed, with some still under evaluation.
What AARO actually concluded
AARO’s Historical Record Report: Volume 1 reviewed allegations about U.S. government programs, recovered materials and alleged efforts to reproduce non-human technology. Its stated finding was that the office had no evidence for the reverse-engineering narrative supplied by interviewees.

AARO also said the aggregate findings of U.S. government investigations to date had not identified even one UAP case representing off-world technology. That is a conclusion about the investigations and claims reviewed so far—not a declaration that every unexplained observation or every government record has been conclusively resolved.

Most claims were rejected, but the review was not presented as universal
The report says AARO disproved most of the claims it examined. It also says some claims remained under evaluation. Consequently, the report does not support either of these broader statements: that every allegation has been disproved, or that every UAP report has been explained.

How to interpret “no evidence”
“No evidence” in this context means AARO did not find substantiating evidence for the specific reverse-engineering narrative presented by its interviewees. It does not establish that unidentified sightings are impossible, nor does an unexplained sighting by itself establish an extraterrestrial origin.
| Claim or observation | What the official finding supports |
|---|---|
| An observation is still unidentified | It may remain unresolved; unidentified does not mean confirmed extraterrestrial. |
| Interviewees describe a government reverse-engineering program | AARO reported no supporting evidence for the narrative it reviewed and said most claims were disproved. |
| A UAP case involves off-world technology | AARO said investigations to date had found no such case. |
| A material is alleged to be from an alien vehicle | The allegation must be distinguished from laboratory analysis of the material. |
The alleged “alien” metal specimen
AARO reported that it contracted Oak Ridge National Laboratory in 2024 to assess a metallic specimen publicly described as coming from an extraterrestrial vehicle. In the report summary, AARO characterized the sample as ordinary terrestrial material with no exceptional qualities.
Rank #2
That assessment addresses the specimen examined by the laboratory. It does not prove that every material associated with a UAP allegation has been tested, and it does not convert an unverified origin story into evidence of a government program.

What the March 8, 2024 Pentagon statement means
The Pentagon’s public statement accompanying the report is listed in AARO’s official congressional and press index as dated March 8, 2024, with Maj. Gen. Pat Ryder identified as the speaker. The available record establishes the date and attribution; the statement’s exact wording should not be treated as a quotation unless checked against the original release.
Rank #3
Does AARO’s archive contain every UAP record?
No. AARO’s reading room includes responsive Freedom of Information Act material relating to AARO since its establishment in July 2022. AARO cautions that the reading room is not an exhaustive reference for UAP records held across all U.S. government agencies. The absence of a document in that collection therefore cannot, by itself, prove that no related record exists elsewhere.
How people with firsthand program knowledge can report information
AARO accepts initial reports from current or former government employees, service members and contractor personnel who have direct knowledge of U.S. government UAP-related programs or activities dating back to 1945.

- The reporting channel is an initial contact point for firsthand information.
- It is not a place to transmit potentially sensitive or classified information.
- People should follow the form’s instructions and appropriate security procedures rather than placing classified details in an ordinary submission.
What remains unknown
AARO’s findings do not identify the cause of every UAP report. They also do not independently settle every allegation that may exist outside the claims and records reviewed for the historical report. The defensible conclusion is narrower: based on the investigations and evidence AARO described, the office found no support for the reported U.S. government reverse-engineering narrative and no investigated UAP case representing off-world technology.
