About UCD

UCD restructures publicly released UAP records into individually verified, comparable incidents rather than raw documents — so patterns across time, geography, and phenomenon type can actually be examined instead of buried in file counts. Every incident is scored on a credibility tier (evidentiary weight, not how dramatic the account sounds) so the record can be filtered down to only the cases that can actually support a claim.

Credibility tiers

Tier A — sensor/physical-evidence corroborated and/or formally reviewed with a stated confidence rating.
Tier B — sensor, radar, IR, or FMV contact logged in real time, no formal review.
Tier C — multi-witness or institutionally documented narrative, no sensor data.
Tier D — single-source, secondhand, or thin narrative.

Have a source document describing a UAP incident? Anyone can submit one for review — it stays off the dashboard until a curator verifies and publishes it.
