More than 20 years after his retirement, former CBS anchorman Walter Cronkite says he still regrets giving up his career. The urge to return to the front lines hits the 85-year-old broadcast legend especially hard during major news events such as the Sept. 11 attacks. "When the big story is breaking, you want to be there," he said. "I knew that was going to happen, I just didn't know it was going to happen over so many years."
