A year ago today

Here's a look back from a blogger, Brendan Loy, whose Irish Trojan's Blog was one of the voices from New Orleans in the middle of Hurricane Katrina, that attracted the attention of readers all over the world. In this post, he links to other bloggers who were covering the storm then, to his posts from the time, and other thoughts. (Among them, a link to the interesting work on the storm surge on WunderBlog by Margie Kieper, The Invisible Coastline.)
Among them, Loy links to a posting from WizBang Blog, another blog that was covering the arrival of the storm a year ago. This post, The Katrina Video:

Congress confiscated a video of the floodwall collapsing and refused to let the public see it until (a perfectly timed) 10 months after the storm. - Well after the storm passed but a few months before the current 1 year anniversary hype.
You've probably never seen it, but we have video taken by New Orleans firefighters as the 17th street canal floodwall was actually in the process of breaking during Katrina.
..New Orleans was doomed with or without Katrina, we just didn't know it. A good high tide puts more water in the canal than this. As the video shows, the water was barely higher than normal levels. The walls could have failed on a decent high tide.

Here's WizBang's anniversary thoughts.
