The "omg aliens" media card always seems to get pulled out when there's no $CURRENT_OUTRAGE and people are looking for something. It's like filler content when there's nothing else to rile people up.
When was the last time a UFO/aliens story was competing for air time with a major real world news event (disaster, protest, shooting, terrorist, election, etc)?
Well, the top story right now is a major dam in a war zone having been destroyed. Given that this story is coming out right now... literally right now?
That story is below the fold, as a small subsection on CNN.com. Their current major top story is "New York City’s air pollution among the worst in the world." It's clearly a slow news day.
