For the curious among us
This is a growing field guide to UFO encounters and the culture around them. We collect notable reports, explain their context, and point you to the material you can read for yourself.
What we mean by UFO and UAP
UFO means unidentified flying object. NASA uses UAP for unidentified anomalous phenomena: observations that cannot be identified as aircraft or known natural phenomena with the available information. Both terms describe an identification problem. Neither means alien. Unidentified describes a limit of the available information. It doesn’t identify an origin.
NASA’s UAP research and independent studyThe record and the story
Encounter files distinguish witness reports, documentary evidence, and unresolved questions. Lore articles explore the histories and claims that gather around those events. Dedicated people profiles examine the lives, work, and accounts of the figures behind the research, reporting, and stories. A report being genuine does not mean its interpretation is correct.
Sources before certainty
We favor original documents, official archives, firsthand statements, and useful measurements over dramatic retellings. Official sources can still have limitations; their value is that readers can inspect what they actually say. Every case, field note, and person’s profile links to its sources.
Images set the scene
The UFO and landscape artwork sets the scene and does not depict the reported events. Each illustration is labeled “Not a real photo.” Historical photographs and documents are identified and credited beside each image.
How the archive is made
uap.fun is made with AI. Research agents search archives, newspapers, and official records for sources; the case files, field notes, and profiles are drafted with AI; and separate fact-checking passes test each substantive claim against the sources it cites. Translations are produced the same way. Tyler sets the editorial direction and spot-checks finished pages, but not every page is read by a person before it goes live. Mistakes can slip through, which is why every claim links to something you can check.

Our growing collection includes 87 encounters, 9 field notes, and 22 people. The aim is to build carefully: useful context, traceable sources, and space to revise a conclusion when the evidence changes. The case files and their sources are also free to download as an open dataset, for anyone who wants to map, count, or dig further.
