Chuck, that's the neat thing about these type of shows; they can spark an interest and we can learn more through research.
Years ago I had learned about the Johnstown flood disaster resulting from the failure of South Fork dam; I recall that there had been calls to reinforce the dam before watching that episode, and seeing the computer generated effects reinforces the horrible event that occurred. All in all it's a decent series. Compared to the general garbage on TV today, it's very interesting and serves to remind us of our nation's industrial roots.
