Unidentified: Inside America's UFO Investigation

HISTORY | 9:00 pm

Season 2 comes to a close with two final back-to-back episodes, starting with "Sightings Surge," wherein Luis Elizondo utilizes some new cutting-edge technology to scrutinize a series of UFO videos from 2019, a year that saw a sharp uptick in the sightings of unidentified flying objects. Then, in the finale "Extraterrestrial Encounters," Elizondo ponders an invisible threat these mysterious aircraft may pose, something not previously considered among the five "observable characteristics" of UFOs.
