(NewsNation) — The Pentagon’s UFO office has released a report indicating a piece of metal purportedly recovered from a UAP likely originated on Earth.

The sample was analyzed by Oak Ridge National Laboratory (ORNL) in Tennessee, which said that despite claims it was an alloy not found on this planet capable of acting as a terahertz waveguide to generate antigravity properties, it was not extraterrestrial in origin.

The lab could not verify the precise historical origin of the sample, in part because of an unclear chain of custody, but said it is consistent with scientific experiments of the time.

UAP Sample

The sample came from Blink-182 frontman Tom DeLonge’s To The Stars Academy, an independent research organization that focuses heavily on the possibility of extraterrestrial life.

In a press release, the group described the material as a magnesium-zinc-bismuth sample, saying there is “no precedent for this structured combination of materials.”

It isn’t clear who gave the sample to the group or where that person obtained it, but the reference to it being recovered from a UAP crash in or around 1947 suggests it is purported to be from the famous Roswell incident.

The Roswell Incident

America’s most famous UFO event, the Roswell incident, began in 1947 after rancher William “Mac” Brazel discovered debris near his ranch just outside of Roswell, New Mexico.

The country was in the middle of a flying saucer craze that Brazel was unaware of since he did not own a phone or radio. However, after telling the local sheriff about his findings, the sheriff alerted the U.S. Air Force.

An initial press release from the Air Force said the military had recovered debris from a flying disc, bringing national attention to the story. Within a day, the Air Force retracted the claim and said the debris came from a conventional weather balloon.

In 1978, a retired officer said the claim was a cover-up and speculated that the debris was of extraterrestrial origin, sparking a conspiracy that has continued for decades.

In 1994, an Air Force report revealed the weather balloon story was indeed a cover-up, but not of alien visitation. The debris actually came from a Project Mogul test. The classified surveillance program was developing high-altitude balloons to monitor nuclear tests, and one such balloon was what Brazel found on his land.

Despite repeated denials from the military, many continue to believe that it was an alien ship that crashed in Roswell, sparking wide-reaching conspiracy theories around the incident and government responses.

A scientific experiment

The Pentagon’s All-domain Anomaly Resolution Office (AARO), tasked with investigating reports of UAPs, issued a report along with the ORNL report. AARO said there is no reason to believe the metal was from a nonhuman source.

The ORNL report stated that scientific experiments of the time included widespread research on magnesium alloys, including those with zinc and bismuth, for aircraft and weapons systems. Because of the unclear chain of custody and the fact that failed scientific experiments are rarely documented, the lab said the exact origin was not determined.

“Regardless of the specimen’s attributability to a specific research project, it is consistent with well-documented Mg alloy research projects during the mid-20th century and is otherwise unremarkable,” the report reads.

Analysts also found no evidence the metal would support acting as a terahertz waveguide.

The report is the latest from AARO that attempts to push back against claims the agency is aware of and hiding extraterrestrial activity. An earlier report found there was no evidence of extraterrestrial origins for UAPs, though not everyone has been accepting of the agency’s findings.
