PORTLAND, Maine - Chet Lunner is a former editor of the Portland Evening Express newspaper. But the biggest story that he's encountered, by far, is the one that happened after he left journalism: the terrorist attacks of September 11, 2001. By then, Lunner was working for the federal government. As the 15th anniversary of the attacks approaches, Lunner talks with MPBN's Morning Edition host Irwin Gratz about where he was that fateful day, what it meant for his career in government, and what worries him today.
