Soldiers recount stories of strange objects in the sky. Is there a normal explanation for this, or did they just uncover evidence of alien life? With the recent declassification of military records, service women and men are coming forward for the first time to share eyewitness tales of unexplained events from the front lines – events for which no training could have prepared them. From mystifying lights to terrifying apparitions and mechanical mysteries, this series launches viewers into the action in an immersive way.
