Expand all Collapse all IFOs An IFO is an “identified flying object”: a report that began as a UFO because the witness or sensor operator could not immediately identify it, but which later turns out to have a conventional cause. The most important point is that “UFO” or “UAP” is a status label, not an origin label. 241 pages Read more A Head On Aircraft Can Look Like A St...

Read more Status Labels UFO Does Not Mean Alien | IFOs UFO and UAP are status labels for unresolved identification, not proof of extraterrestrial craft or unknown physics. 6 pages +Show subtopics Read more AARO Claims What AARO Says Evidence Still Has Not Shown | Status Labels AARO separates unresolved reports from verified origin claims, keeping prosaic explanations and extraordinary claims on different evidence standards. Read more Label Changes When Does a UFO Stop Being a UFO? | Status Labels A sighting can move from unidentified to identified when new timing, location, sensor, or comparison data support a prosaic match. Read more NASA Data Why NASA Focused on Better UAP Data | Status Labels NASA's UAP study shifted attention from speculation to the need for standardized, reproducible observation data. Read more Stigma Why UFO Wording Changes What People Report | Status Labels Loaded UFO language can discourage serious reporting, while clearer UAP wording can help aviation and defense systems collect better data. Read more Unresolved Cases Why Unresolved Does Not Mean Alien | Status Labels Unresolved UAP cases may reflect missing records or weak data rather than evidence of extraterrestrial craft. Read more Strong Cases What Makes a UFO Report Harder to Explain | IFOs A report becomes more interesting when common explanations are tested against specific data and still fail to fit. 6 pages +Show subtopics Read more GEIPAN Not All Unidentified UFO Cases Are Equal | Strong Cases GEIPAN's split between missing-data cases and investigated unknowns offers a clearer way to avoid treating every unexplained UFO report as equal. Read more Time checks The Details That Make UFO Reports Testable | Strong Cases A precise time, location, direction, elevation, and duration can turn a strange story into a testable case against flights, satellites, planets, and... Read more Lakenheath The Radar Visual Case That Would Not Settle | Strong Cases The Lakenheath-Bentwaters incident shows why radar-visual UFO cases can be unusually interesting while still vulnerable to propagation and... Read more Multi sensor When Do Multiple UFO Records Really Agree? | Strong Cases Multi-sensor cases become stronger only when radar, infrared, visual, and witness records converge without sharing the same failure mode. Read more Nimitz Why the Nimitz Tic Tac Still Matters | Strong Cases The Nimitz case remains debated because pilot testimony, military context, radar claims, and infrared video create a structured but incomplete... Read more UK Files What the UK UFO Files Reveal | IFOs The UK MoD files show the practical limits of public sighting collection and why a hotline can gather many weak reports. 6 pages +Show subtopics Read more Lantern surge Did lanterns fuel the Mo D UFO surge? | UK Files A rise in orange-light reports showed how lantern releases, media attention and easy reporting could inflate UFO sighting numbers. Read more Light reports How ordinary lights became Mo D UFO reports | UK Files The MoD sighting lists show how distance, speed and formation can be misread when a witness sees only lights in the sky. Read more Condign What Project Condign really asked | UK Files Project Condign tested whether decades of UAP reports justified intelligence interest, not whether every sighting could be solved. Read more Desk closure Why Britain shut its UFO desk | UK Files The UFO desk closed because decades of reports had not shown a defence threat, while the workload kept growing. Read more Hotline data Why easy UFO reporting made weak evidence | UK Files The MoD hotline made sightings easy to report, but most entries lacked the measurements needed to identify what witnesses saw. Read more Unresolved Cases Why Some UFO Cases Stay Open | IFOs Some cases remain open because evidence is incomplete, conflicting or too ambiguous for a confident ordinary identification. 6 pages +Show subtopics Read more Active Archives Can Old UFO Reports Become Useful Later? | Unresolved Cases An unresolved case may become useful later when analysts compare it with clusters, patterns and newly available records. Read more Weak Files When Is Unresolved the Honest Answer? | Unresolved Cases A weak UFO file can be more honest as unresolved than as a forced identification with evidence it does not actually support. Read more Starlink Gaps Why Satellite Lights Still Leave Open Cases | Unresolved Cases Even common satellite lights can remain unresolved when reports lack altitude, direction, imagery or reliable timing. Read more Witness Limits Why Sky Witnesses Disagree So Often | Unresolved Cases Distance, speed, size and silence can all be misjudged in open sky, turning ordinary objects into unresolved reports. Read more Sensor Context Why UFO Videos Need More Than Footage | Unresolved Cases Military or aviation sensor footage can preserve useful evidence, but without range, calibration and platform motion it may still mislead. Read more Venus Is That UFO Really Venus? | IFOs Venus, Jupiter and Mars can appear to pulse, change colour or hover when viewed low through haze or moving cloud. 6 pages +Show subtopics Read more Sky Checks How to Test the Planet Explanation | Venus A planet explanation becomes stronger only when the reported time, direction, elevation, duration, and motion match the sky. Read more Formations When Planets Look Like a Formation | Venus Venus, Jupiter, Mercury, Mars, and the Moon can line up in twilight and look like an arranged formation of strange lights. Read more Following Lights Why a Planet Seems to Follow You | Venus A fixed planet can seem to follow a car or drift against buildings when foreground objects move across the line of sight. Read more Color Shifts Why Low Planets Seem to Change Colour | Venus Low planets can pulse, redden, or flash colours when their light passes through turbulent air, haze, and thin cloud. Read more Bright Venus Why Venus Can Look Too Close | Venus Venus can look unnaturally close because its brightness overwhelms the weak distance cues available in twilight skies. Read more Weather Records Weather Clues That Explain Strange Lights | IFOs Haze, fog, cloud layers and visibility records often decide whether an ordinary object would look distorted or hidden. 6 pages +Show subtopics Read more Cloud vanish Did the UFO vanish into cloud? | Weather Records Low or broken cloud can make a steady light seem to blink out, vanish upward or pass behind an invisible barrier. Read more Blue Book The weather questions Blue Book needed answered | Weather Records Project Blue Book treated missing weather details as a reason a UFO report could remain impossible to evaluate. Read more Fog limits When fog makes UFO distances fall apart | Weather Records Fog can make a nearby ordinary light look distant, large or suddenly appearing when visibility drops below familiar judging range. Read more Rain halos When rain turns lights into UFOs | Weather Records Rain, mist and wet air can put halos around ordinary lights and make aircraft, beacons or runway lights seem larger and stranger. Read more Haze planets Why a low planet can look alive | Weather Records A bright planet near the horizon can redden, blur, shimmer or seem to move when thin haze sits along the line of sight. Read more Wind Data Following a UFO With the Wind | IFOs Wind direction and altitude data can show whether a slow object was likely a balloon, lantern or other drifting source. 6 pages +Show subtopics Read more Wind Direction Are you reading the wind backwards? | Wind Data Wind direction labels say where air comes from, not where a balloon goes, so a simple reversal can spoil a drift test. Read more Trajectories Can a model trace the UFO's drift? | Wind Data Trajectory runs can test whether a plausible balloon release point and altitude match a reported path, while still showing uncertainty. Read more Lanterns Do orange lights move like lanterns? | Wind Data Clusters of warm orange lights that rise, spread, drift downwind and fade can match the short-lived behaviour of sky lanterns. Read more Surface Wind When ground wind tells the wrong story | Wind Data A ground weather reading can help a UFO check, but it can also point the wrong way when the object is higher than the mast. Read more Soundings Why balloons can change course overhead | Wind Data Radiosonde profiles can show why a balloon seems to curve, slow or change direction as it climbs through different wind layers.
