Lue Elizondo was a former intelligence officer who worked in the shadows on sensitive national security issues, including 10 years heading up the Advanced Aerospace Threat Identification Program (AATIP), which investigates UFOs.

Since the public seeks to link UFOs to extraterrestrials, the government now refers to UAPs or Unidentified Aerial Phenomena.

Elizondo believed in the existence of mysterious phenomena after speaking with U.S. military sources who had seen UFOs, watched recordings of them, and seen photos.
