Memo Describes Black Object Hovering Over Ridge for 20 Seconds, Then Dropping Into Canyon
The documents don’t explain why agents were deployed, and the FBI said it had nothing to add.

The FBI has not explained why agents with thermal equipment were sent to observe a sensitive site in the western United States. A Pentagon memo describes a black, triangular object that hovered, then accelerated silently, but offers no evidence of its speed or a connection between the deployment and the sighting.
The FBI has not explained why it sent agents equipped with optical and thermal gear to a site considered sensitive to national security in the western United States. The agents reported seeing a black, triangular object, according to the Liberation Times, which cited a Pentagon memo documenting their accounts.
According to the memo, the object rose vertically above a ridge and hovered for about 20 seconds without drifting noticeably. It then accelerated abruptly, turned, and descended into a canyon. The agents heard no sound. A ground inspection the next day found no debris, burn marks, or damage to vegetation.
What the Agents Saw
The agents described an object that was “black, nonreflective, and most similar to a delta-wing drone.” They estimated its wingspan at between 3 and 4.5 meters. The Pentagon’s UFO investigation office estimated a nearly identical range. One agent wrote that the object appeared warmer than its surroundings, with a uniform thermal signature across its body and no exhaust.
The memo cautions that the object’s speed was not measured with an instrument. The agents compared its departure speed to that of a fighter jet, but that was only a visual estimate.
What the Documents Don’t Explain
The documents do not explain the purpose of the deployment or identify the agents. They do not say whether the FBI’s Special Investigations Unit was involved or whether the deployment was related to a suspected crime. The memo includes nine images of the same landscape, with a triangle-like shape in different locations, but does not identify them as photographs of the incident.
Rep. Anna Paulina Luna told journalist Matt Laslo: “We are working directly with them for our investigation.” The FBI has previously confirmed that it investigates unidentified phenomena when there is concern about a violation of federal law, but nothing has been made public about this case.
Asked about the deployment, the FBI replied in a single sentence: “We have nothing to add to the documents.” The Pentagon office wrote that the incident warrants further examination because its descriptions closely resemble accounts of other incidents in the area.
