Earlier this year, dozens of reports were rolling in from all over the world
about incredibly loud sounds like airplane engines coming out of the sky with no explanation. Some call them "apocalypse sounds," and others "Earth sounds." Either way, when you hear them, they are downright scary.

have unearthed two more vids online - one of a sound in Germany recorded earlier this month, and another from a freaked-out woman in Florida in March, who heard the noise over her house.
