TV Ancient Aliens - Season 1 Episode 5 : The Return Ancient Aliens - Season 1 Episode 5 : The Return 7/10 by 287 users There is evidence that suggests we experienced 20th century alien contact. In 1942, the Battle of Los Angeles involved the US military and Air Defense allegedly fighting a UFO. WWII Allied Air Force planes were buzzed by balls of light that some think could have been extraterrestrial. And the alleged crash of a flying saucer in Roswell, New Mexico in 1947 propelled the world into the age of UFOs. For decades, some people have been searching for the sounds of extraterrestrial intelligence, while others have been sending messages out into deep space. What would happen if aliens answered... or came calling? What protocols exist to determine who would speak on behalf of mankind, and how might we communicate? What happens if they return? Some believe they already have.
