Timeline of Ufology

This is a timeline of key events in the reported, sometimes ostensible study of unidentified flying objects (UFOs). Note that ufology, nowadays also known as UAP studies, is not an established academic subject. The timeline primarily includes inquiries into the subject from governmental commissions, public institutions, and private sectors. It also includes the publication of books and reports of alleged evidence.
