A story by the The Sun-Sentinel of South Florida, declaring that UAL (United Airlines) had filed for bankruptcy, sent shares of UAL crashing this morning. Only problem? The story was six years old: The story was actually published on Dec. 10, 2002, when the world’s second-largest airline by passenger traffic entered Chapter 11 bankruptcy. It emerged four years later, in 2006. Jean Medina, a spokeswoman for the airline said the Sun-Sentinel story was untrue.  Losing nearly all their value, shares of United traded at one cent in late morning on the New York Stock Exchange, down 99.92 percent, or $12.29.
