BAD DAY FOR: Old news, after a 2002 story about United Airlines’ bankruptcy filing appeared on Bloomberg’s ticker, briefly sending UAL’s stock down to about $3 a share, from about $12. The story was posted to the Bloomberg Professional service by a reporter from the Florida-based Income Securities Advisors, who found the item after doing a Google search for “bankruptcy 2008.” (The Washington Post)
