United States.U.S. East Coast · a civilian aircraft films a small, fast object

In 2019, on a date that has not been made public, an infrared sensor mounted on a civilian aircraft, not a military one, recorded 20 seconds of video over the U.S. East Coast. An infrared sensor builds its image from the heat that objects give off, not from visible light. The U.S. Navy sent a report of the event to the Pentagon office that studies these phenomena, the All-domain Anomaly Resolution Office (AARO).

The video came with a follow-up report titled "Range Fouler Debrief" (in military jargon, a range fouler is anything that strays into an area set aside for exercises or tests). According to the lines AARO quotes from it, the observer said the object showed "flight characteristics unlike anything [the observer] had seen in 28 years [of service] for the U.S. Air Force and U.S. Navy." The brackets are AARO's. The quote does not say whether those years were military service or civilian work for both branches, which matters because the aircraft was civilian; either way, they point to long experience in aviation. The report describes the object as "small" and "travelling in a straight line [in the] opposite direction at high speed."

AARO also published a second-by-second description of the video, and it shows far less than the observer describes. From second 1 to 11, an area of contrast (a patch that stands out from the background) is visible near the center of the screen. Between seconds 12 and 14, the sensor changes its zoom and display mode, the image flashes white and, when it returns, the patch leaves the frame on the left. From second 15 to 20, the sensor changes settings again and the screen goes white, with nothing on it. The object is therefore visible for about 11 of the 20 seconds, and the clip ends on a blank white screen, not with the object moving away in the frame.

AARO released the video on July 10, 2026, in the fourth batch of its PURSUE release program. What is known of the report comes from the lines AARO quotes on its page at DVIDS, the Defense Department's image distribution service; they do not give the exact date or the area.

The video comes with the testimony of the person who saw the object: a direct quote, recorded in a formal follow-up report, from someone with 28 years of work for the Air Force and the Navy who says they had never seen anything fly like this.

The video, however, cannot back up what the observer describes. The object is visible for about 11 seconds and the sequence ends on a white screen, so the recording does not confirm the path "in a straight line [in the] opposite direction at high speed" that the report records. The testimony is richer than what the sensor managed to capture.

No source proposes a cause. In its 2024 annual report, AARO stated that 174 cases had been resolved, all to conventional objects including balloons, birds, drones, satellites and aircraft, and added that many other cases remain unresolved. By our own reasoning, not any source's, the simplest explanation for a small, fast object seen from an aircraft is another aircraft passing it in the opposite direction, or a small drone. When two aircraft pass each other, each sees the other go by at the sum of their two speeds, which gives exactly the impression of moving in the "opposite direction at high speed" without the object moving in any unusual way. That the observer did not identify it at the time does not rule out that reading.

Without flight data from either aircraft or a check against air traffic for that date and area, that reading is the simplest one, but it is not confirmed.
