UFOs and Intelligence — a timeline of UFO events and relevant military intelligence activities, by George M. Eberhart of CUFOS

I just found this on the CUFOS website (legacy website of the late J. Allen Hynek), via the UAP News Center. As the title says, this is an up to date timeline of UFO events and related intelligence activities. This version is dated December 30, 2023, and is a monstrous almost 1000 pages pdf document, complete with references and sources and links. It dates back to the year 743.
