Today is the day that extraterrestrials make contact with Earth! According to a retired NORAD officer who has studied alien phenomenon since WW2, a fleet of UFOs will perform a massive display for hours over the world's principal cities today, the first step in mankind's acceptance of alien existence. Drawing upon his military experience and a wealth of historical data from NORAD intelligence, Stanley Fulham has concluded in his recently published book, Challenges of Change, that October 13, 2010 is the date of first contact. Although they won't land or communicate today (so as not to cause a worldwide panic), the aliens come with the benevolent intention of saving humans from ecological disaster. Hoopy froods should know where their towels are.

"Uncontacted" tribe contacted in Javari region of Amazon
A team of Brazilian anthropologists has made contact with a group of indigenous people in the Amazon region. They had initially only wanted to learn about uncontacted groups indirectly, but chose to seek out this group to make sure they weren't being exploited by a neighboring group.
