Report from 307th Bomb Group during Operation Dagger
"Generall agreed by observers that it was a single jet propelled A/C employing probably rocket assists with tremendous reserve power, more than normal curising speed for jets of the 1947 variety."
Unknown speaker, USAFE Intelligence / USAFE
Evaluation of Holland sighting
"Their answer was that some reliable and fully technically qualified people have reached the conclusion that 'these phenomena are obviously the result of a high technical skill which cannot be credited to any presently known culture on earth.'"

Unresolved UAP Report, United Arab Emirates, October 2023
The United States Central Command submitted a report of an unidentified anomalous phenomenon to the All-domain Anomaly Resolution Office (AARO) consisting of four minutes and 57 seconds of video footage from an infrared (IR) sensor aboard a U.S. military platform in 2023. An accompanying mission report, DoW-UAP-D23, mentions a UAP was observed during the mission. Video Description: 00:00-01:55: No content. 01:56: An area of contrast becomes distinguishable against the background in the center of the right side of the display. 02:04: The IR sensor pans to center on the area of contrast. 02:14: The sensor field-of-view narrows to zoom in on the area of contrast. 02:15-03:26: The area of contrast remains generally in the center of the sensor field-of-view. 03:27-04:57: The sensor motion causes the area of contrast to move erratically across the display. Due to this motion, the sensor system repeatedly loses and reacquires the area of contrast within the center area of the display. This video description is provided for informational purposes only. Readers should not interpret any part of this description as reflecting an analytical judgment, investigative conclusion, or factual determination regarding the described event’s validity, nature, or significance.

Unresolved UAP Report, United Arab Emirates, October 2023
The United States Central Command submitted a report of an unidentified anomalous phenomenon to the All-domain Anomaly Resolution Office (AARO) consisting of 43 seconds of video footage from an infrared sensor aboard a U.S. military platform in 2023. An accompanying mission report, DoW-UAP-D23, mentions a UAP was observed during the mission. Video Description: 00:00-00:17: An area of contrast remains generally within the top left quarter of the display. 00:17-00:18: The sensor pans from right to left, causing the area of contrast to pass through the center of the display. The sensor then pans from left to right, causing the area of contrast to return to its approximate initial position within the sensor field-of-view. 00:29: The sensor stops tracking the area of contrast, causing it to leave the sensor field-of-view on the left side of the screen. 00:30-00:43: The sensor resumes its motion relative to the background but does not reacquire the area of contrast.

Unresolved UAP Report, Syria, October 2024
The United States Central Command submitted a report of an unidentified anomalous phenomenon (UAP) to the All-domain Anomaly Resolution Office (AARO) consisting of five seconds of video footage from a full-motion video (FMV) camera aboard a U.S. military platform in 2024. An accompanying mission report, DoW-UAP-D32, described the UAP as consisting of a “misshapen and uneven ball of white light,” and reported that a “light/glare halo effect” occurred at the top of the FMV feed. Video Description: 00:01-00:03: Two semi-transparent, irregularly shaped orange areas overlay the background imagery, persisting for less than two seconds each.

Unresolved UAP Report, Syria, October 2024
The United States Central Command submitted a report of an unidentified anomalous phenomenon (UAP) to the All-domain Anomaly Resolution Office (AARO) consisting of six seconds of video footage from a full-motion video (FMV) camera aboard a U.S. military platform in 2024. An accompanying mission report, DoW-UAP-D32, described the UAP as consisting of a “misshapen and uneven ball of white light,” and reported that a “light/glare halo effect” occurred at the top of the FMV feed. Video Description: 00:02-00:04: An area of irregular color and brightness, mainly consisting of white and red highlights, appears near the center of the top edge of the sensor display. The area extends to a width of approximately one-third of the horizontal frame, with a vertical area comprising approximately one-sixth of the viewing area. Overall, its shape is best described as a horizontally-oriented half-oval bisected along its major axis. This video description is provided for informational purposes only.
