This January Project Blue Book reopens its pages for a second season of investigating UFO sightings and crashes.

This season 'Captain Michael Quinn' (Michael Malarkey) and 'Dr. J. Allen Hynek' (Aiden Gillen) realise they are part of a wider government conspiracy as they investigate the infamous crash in Roswell, New Mexico and the truth of Area 51.

These sophomore season billboards were photographed along the Sunset Strip and San Vicente Boulevard from December 15, 2019 to January 10, 2020.

Fans of the History channel drama can also enjoy these season one billboards for Project Blue Book.
