China News Service, October 24 (Xinhua) Comprehensive report: On October 23, local time, the U.S. Department of Defense released the latest files on "Unidentified Flying Objects (UFOs)" and other "Unidentified Anomalous Phenomena (UAP)". This is the seventh batch of such documents released by the U.S. government since May. The newly released files contain a total of 28 documents in PDF format.
Mysterious "black triangle" attracts attention
In the newly released documents, a large "matte black triangle-shaped" flying object recorded in 2026 has attracted widespread attention.
CBS reported that in June 2026, three federal agents saw an unidentifiable mysterious flying object near a U.S. security facility: a large "matte black triangle."
"While observing the western horizon, we quickly spotted a large, matte black triangular object that resembled a delta-wing drone," federal agents said in the report. "We estimated the object had a wingspan of approximately 9 to 15 feet, a length of 6 to 9 feet, and a thickness of 1 to 2 feet."
According to reports, the flying object rose vertically for about 90 meters above the ridgeline without tilting or swinging, then hovered, flew away horizontally after about 20 seconds, and reached a distance of 2.4 kilometers in 3 seconds. The speed was "comparable to a fighter jet" without making any sound, and finally disappeared without a trace.
One of the three federal agents was equipped with a monocular thermal imaging device capable of infrared tracking, but no "discrete heat source related to propulsion power" was detected on the object, the filing states.
The report also stated that a ground survey of the canyon area the next day found no signs of debris, impact marks or damage to vegetation.
The incident is reportedly similar to other incidents reported by federal agents in the western United States and detailed in previously released UAP documents.
The U.S. Department of Defense's "Global Anomaly Resolution Office" stated that the morphological characteristics and movement trajectories of related sightings are very similar to other reported incidents in the western United States, and further investigation is necessary.
What other newly released documents are there?
According to the American Axios news website, in a 1954 report, a Swedish pilot said that he and his crew witnessed a "flying saucer".
The pilot said: "Before, I was extremely skeptical of all those stories about mysterious objects (i.e. "flying saucers"). However, now I really don't know what to think, but I do feel that what we were seeing was some kind of robot."
In a 1957 report, a B-52 bomber pilot said he witnessed a UFO over Saudi Arabia; in 1949 and 1952 reports, witnesses claimed to have spotted a UFO on Santa Catalina Island, California, USA. According to reports, the island is one of the first places in the United States where "flying saucers" were discovered.
Another document was a handwritten letter describing a UFO sighting.
The letter read, "At around 8pm on April 28, my wife and a school teacher saw six objects in the sky. They did not appear in groups, but existed alone. A few minutes later, she went to her daughter's house in the next block. She, her daughter and her grandson saw four more such objects. They were all flying in the same direction."
A handwritten notation on the document stated that the Air Force believed the incident "lacked sufficient data to allow an assessment."
U.S. President Trump said in February that relevant documents would be made public "given the strong public interest." Prior to this, former US President Obama said in an interview that alien creatures "are real, but I have never seen them." This statement further aroused concern. However, Obama later clarified that from a statistical point of view, there is a possibility of life in the universe, but he "saw no evidence" during his term as president.
On May 8, the U.S. Department of Defense began to release documents related to "Unidentified Flying Objects (UFOs)", including videos, photos and original documents. US media pointed out that although many of the contents are interesting, none of them provide conclusive evidence to confirm the existence of extraterrestrial life.
