Instrumental evidence of anomalous craft
This is a dynamic list
and may never be able to satisfy particular standards for completeness. You can help by adding missing items.
Instrumental detection of anomalous craft encompasses data gathered by radar, ELINT receivers, spectrum analysers, magnetometers, seismometers, and other scientific or military sensor systems that record anomalous signatures attributed to unidentified aerial phenomena or their associated technologies. Unlike video or photographic evidence, instrumental data is captured by calibrated instruments with known performance envelopes, allowing quantitative analysis of speed, altitude, electromagnetic spectrum, and other physical parameters. Calibrated military sensors operate against known baselines, making anomalous returns quantifiable rather than subjective; the Nimitz encounter involved simultaneous returns on radar, infrared, and four aviators' visual observations — a level of cross-sensor corroboration rarely achieved in civilian sightings. By 2024, Ryan Graves reported that more recently observed anomalous craft were undetectable on infrared, reportedly indicating active thermal signature management beyond any known technology. This catalogue includes only cases where calibrated instrument data (radar tracks, electromagnetic intercepts, spectral readings, seismic data) constitutes the primary evidence; infrared video captures such as the FLIR1 video, Gimbal, and Go Fast are catalogued under Pentagon UAP videos.
Catalogue
| Dataset | Date | Sensor type | Location | Description |
|---|---|---|---|---|
| 1952 Washington D.C. radar returns | July 1952 | Airport surveillance radar | Washington National Airport; Andrews Air Force Base | Multiple radar installations tracked unknown objects over the restricted airspace of Washington, D.C. on consecutive weekends (19–20 July and 26–27 July 1952). Visual confirmation was obtained by airline pilots and F-94 Starfire interceptor crews. The incidents prompted the largest Pentagon press conference since World War II.[1] |
| RB-47 electromagnetic detection (1957) | 17 July 1957 | Airborne ELINT receivers; ground radar | From Mississippi to Oklahoma | A US Air Force RB-47 electronic reconnaissance aircraft tracked an anomalous object simultaneously on its onboard electromagnetic intercept equipment, ground radar at multiple stations, and visual observation by crew members over a flight path of approximately 700 miles and 1.5 hours. The onboard ELINT gear detected a signal at approximately 2,800 MHz emanating from the object's position.[5] |
| Tehran UFO incident radar and weapons-loss data (1976) | 19 September 1976 | Airborne radar; weapons and instruments | Tehran, Iran | Two Imperial Iranian Air Force F-4 Phantom II jets scrambled to intercept a bright anomalous object. The lead aircraft's radar locked onto the target, but when the pilot attempted to fire an AIM-9 Sidewinder, all weapons control and instrumentation simultaneously failed; systems restored when the aircraft turned away. A Defense Intelligence Agency evaluation report rated the case as meeting all criteria for a legitimate study of anomalous phenomena.[6] |
| Project Hessdalen automated monitoring | 1983– | Magnetometers, spectrum analysers, radar, cameras | Hessdalen, Norway | Long-duration automated scientific monitoring of recurring luminous phenomena in the Hessdalen valley. The station has recorded light phenomena exhibiting structured spectral output, radar returns inconsistent with plasma, and magnetic field perturbations synchronised with visual events. Data has been published in peer-reviewed journals including Physica Scripta.[7] |
| Japan Airlines Flight 1628 radar data (1986) | 17 November 1986 | FAA ground radar; airborne weather radar | Over eastern Alaska | Captain Kenju Terauchi and crew observed a walnut-shaped anomalous craft several times the size of an aircraft carrier. FAA radar independently confirmed a primary return in the vicinity of the 747 for 31 minutes. FAA Division Chief John Callahan later testified that a CIA team confiscated the radar data and instructed attendees the event "never happened."[8] |
| Belgian Air Force F-16 radar lock data (1990) | 30–31 March 1990 | F-16 airborne pulse-Doppler radar | Belgium | During the Belgian UFO wave, two Belgian Air Force F-16s obtained multiple radar locks on a triangular object. Onboard instruments recorded the target accelerating from approximately 280 km/h to over 1,800 km/h in seconds while dropping from 3,000 m to 1,000 m altitude — an acceleration of roughly 40g. The radar tapes were publicly released by the Belgian military.[9] |
| USS Princeton SPY-1 radar tracks | November 2004 | AN/SPY-1 phased-array Aegis radar | Off Baja California / San Diego | The Princeton's radar tracked objects descending from approximately 80,000 feet to sea level in less than one second and executing right-angle turns at speeds exceeding Mach 3. Senior Chief Kevin Day observed the returns and vectored the Fravor flight to intercept.[2][3] |
| Galileo Project sensor network | 2021– | Multi-spectral camera arrays, radar, audio, magnetometer | Harvard University, multiple sites | Founded by astrophysicist Avi Loeb to apply systematic scientific instrumentation to anomalous craft detection. Deploys a standardised sensor suite to collect calibrated data. Preliminary results reported anomalous metallic spherule composition in Pacific Ocean samples.[10] |
| InSight lander seismic anomalies | April 2021 | Seismometer (SEIS) | Elysium Planitia, Mars | NASA's InSight lander detected seismic events on Mars that, in the context of exopolitical claims about subsurface Martian civilisations, have been cited as potential evidence of underground activity. Mainstream interpretation attributes the signals to marsquakes; according to Michael Salla, the timing allegedly coincided with purported Galactic Federation of Worlds operations to clear Ciakahrr (Draco reptilian) bases from Mars.[11] |
