The 'Unstoppable' Real Life Backstory

Following up on my post yesterday (with Kenneth Turan's review), things turned out and I was able to take my two sons to "Unstoppable." This is one thriller in which the description "non-stop action" is definitely not a cliché. The viewer is totally pumped by the end, and completely satisfied. But is it really a "true story"? Actually, the movie is "inspired by actual events." Even the most faithful dramatic picture throws in a little license here and there, and it's no exception with "Unstoppable." Plot Spoiler Warning: See the Pittsburgh Post-Gazette, "At Times, 'Unstoppable' Goes Off Track From Reality."
