华盛顿消息——美国国防部最新披露的文件显示，今年美国西部的联邦特工曾遭遇一架大型三角飞行器，它能从静止状态急速升空，全程没有噪音也没有任何排气痕迹。
这些特工的回忆记录在国防部最新发布的UFO（即UAP，不明异常现象）相关文件中。此次周五披露是特朗普总统今年早些时候签署行政命令以来的第七次，该命令要求公开敏感的UAP文件。最新一批文件包含28份PDF文档。
这份三角飞行器的细节记载在两份文件中：一份是国防部全域异常解决办公室（AARO）的备忘录，记录了调查人员对特工的问询情况；另一份是特工向联邦调查局（FBI）提交的签名陈述。
此次遭遇发生在6月，地点是美国西部一处未具名的“国家安全站点”附近。
特工告诉调查人员，他们是被附近另一名在岗特工提醒才注意到该物体的。他们迅速调整位置以便观察，在日落余晖的映衬下，于几英里以西的山脊线上方发现了这架飞行器。
他们在FBI的陈述中写道：“我们随即对西部地平线展开目视观测，很快就看到一个体积不小、无反光、漆黑的三角形物体，外形极像三角翼无人机。我们估算该物体的翼展约为9至15英尺，高度为6至9英尺，厚度为1至2英尺。”
这份FBI文件包含了现场图与飞行器示意图。
AARO的报告指出，这架“不明飞行器正在山脊线上方缓慢、可控且完全垂直地上升。它攀升了约200至300英尺，全程保持完全静止的姿态，没有倾斜、摇晃或摆动。其无反光的哑光黑色表面呈现出连续、无特征的轮廓。”
调查人员写道，此次上升过程中“绝对静音”。
特工向FBI表示，通过红外瞄准镜观察时，该物体“机身整体热信号完全一致，温度高于环境温度，且没有可见排气气体”。
AARO的问询记录显示，当飞行器升至山脊线上方200至300英尺时，它“瞬间”停止移动并开始悬停，静止约20秒。
随后这架飞行器加速驶离，速度“堪比军用战斗机”。特工在几秒内就失去了它的踪迹。
备忘录称：“在高速飞行阶段全程保持绝对静音，未观测到任何撞击痕迹、烟雾、尘土或物理扰动。次日清晨对峡谷排水区的地面勘测未发现任何残骸、地面划痕或植被损坏。”
这一事件与美国西部联邦特工此前报告的其他遭遇类似，这些内容都记载在之前发布的UAP文件中。
2023年5月公布的文件显示，美国联邦执法人员在一处未公开地点报告，曾在两天内目睹橙色球体释放出更小的红色球体；后续一批文件中收录了特工的自述，其中一人描述这些红色灯光“瞬间加速”，另一人则将这些球体比作“从篮球里挤出来的葡萄”。
8月公布的另一案例中，一名特工录制了红外视频，显示两个“黑热”物体以相同的慢速一同移动。
关于6月发生的这起事件，五角大楼指出，AARO表示该事件“值得进一步调查，因为其报告的现象形态特征与运动轨迹，与美国西部地区其他报告事件高度吻合”。

New UFO files include details of strange triangular craft: “Absolute acoustic silence”
October 23, 2026 / 5:02 PM EDT / CBS News
Washington — Federal agents in the western U.S. this year encountered a large, triangular aircraft that zoomed through the sky from a standstill while making no noise or giving off any exhaust, according to new documents released by the Pentagon.
The agents’ recollections were included in the Defense Department’s latest release of files related to UFOs, or UAP, unidentified anomalous phenomena. Friday’s disclosure was the seventh under an executive order that President Trump signed earlier this year mandating the release of sensitive UAP files. The latest batch included 28 PDF files.
The triangular craft is detailed in two documents: a memo from the Pentagon’s All-domain Anomaly Resolution Office describing investigators’ debrief with the agents, and a signed statement the agents gave to the FBI.
The encounter occurred in June near an unspecified “national security site” in the western U.S.
The agents told investigators that they were alerted to the object by a third agent stationed nearby. They quickly repositioned themselves to get a better look, and spotted the craft above a ridgeline a few miles to the west, against the glow of the sky after sunset.
“We initiated a visual survey of the western horizon and almost immediately observed a substantial, nonreflective, dark black triangular object most resembling a delta wing drone,” they said in their FBI statement. “We estimated the object’s wingspan at approximately nine to fifteen feet, its depth at six to nine feet, and its thickness at one to two feet.”
The FBI document included illustrations showing the scene and a representation of the craft.
The AARO report notes that the “unidentified craft was executing a slow, controlled, perfectly vertical ascent directly over the ridge line. The craft climbed approximately two to three hundred feet while maintaining a completely static orientation without tilting, swaying, or wobbling. The non-reflective, matte black exterior presented a continuous, featureless profile.”
Investigators wrote that the “ascent occurred in absolute acoustic silence.”
The agents told the FBI that when viewed through an infrared scope, the object “appeared hotter than ambient temperature with a completely consistent thermal signature across the entire airframe and no visible exhaust gases.”
When the craft was 200 to 300 feet above the ridgeline, it “instantaneously” stopped moving and began hovering, staying perfectly still for about 20 seconds, the AARO debrief said.
The craft then sped off, reaching a velocity “compared to that [of] a military fighter jet.” The agents lost sight of it within a few seconds.
“Absolute acoustic silence persisted throughout the high-velocity phase,” the memo said. “No impact signature, smoke, dust, or physical disturbance was observed. A ground survey of the canyon drainage conducted the following morning located no wreckage, ground scarring, or vegetation damage.”
The incident is similar to other encounters reported by federal agents in the western U.S., detailed in previous releases of UAP files.
In 2023, federal law enforcement agents at an undisclosed location reported seeing orange orbs that released smaller red orbs over a two-day period, according to files released in May. A later batch included the agents’ own accounts, with one describing red lights that “accelerated instantly” and another comparing the orbs to “grapes being expelled from a basketball.”
Another instance, detailed in August, involved an agent who recorded infrared video of two “black-hot” objects moving together at the same slow speed.
Regarding the June incident, the Pentagon noted that AARO said it “warrant[s] further investigation due to the close alignment of the phenomena’s reported morphological features and kinematic profiles with those of other reported incidents in the western United States region.”
