Official reports, contemporary documents and original recordings can establish what was recorded or concluded. Even official material has limits. Secondary reporting adds context. Encyclopaedias are useful starting points and should be followed back to their references.

Coverage by topic

Link checks describe access during research, not proof of a claim. Review flags include inaccessible originals and source limitations. Individual references explain their scope. The original UFO workbook retains its outstanding source-review flags.

Case status labels

These labels describe the state of a case and its uncertainties. They are not ratings of a source or proof of an extraordinary explanation.

Unresolved

The supplied record does not establish a settled explanation. This does not establish an extraordinary origin.

Disputed

Material interpretations or accounts are contested.

Partially explained

A conventional explanation addresses part of the reported event, while other aspects remain disputed or uncertain.

Likely conventional

The supplied record favours a conventional explanation without presenting every detail as settled.

Explained

The supplied record reports a conventional resolution of the apparent performance. This does not necessarily identify the object or settle every account.
