NORAD air base on heightened alert

As the U.S. continues to express concern about the possibility of a North Korean missile test directed toward American territory and the rest of the world holds its breath over a close encounter with an asteroid, several U.S. air bases are on heightened alert. But no one is talking about why. The Cheyenne Mountain Air Station, which houses NORAD – charged with monitoring the North Korea situation – is now at "Bravo-Plus." Other air bases in Colorado, California and Florida are also on heightened alert status. http://www.wnd.com/news/article.asp?ARTICLE_ID=50891
