Terror from the Sky

S3, E21: Across North America there is something strange and frightening circling overhead. Witnesses tell of human-like creatures that float or hover in the skies and often descend to attack. Legends and folklore tell of strange flying creatures, but in the 1940s and 1950s, strange humanoid forms were spotted above small towns, bringing waves of panic. Sceptics claim that misidentification explains these creatures, however the mounting evidence says otherwise. MonsterQuest will analyze the video proof of this monster while scientists work to discover the identity of an eerie corpse that may unlock the mystery of these flying humanoid monsters.
