Eric W's review is
the one to read, as it's the one that got me to read this book. (I had, however, really liked Langewiesche's great book on the new piracy at sea.)
I've little to add--a precise yet remarkably informative analysis of the Hudson landing as it illustrates a lot about modern flying, and even more about modern airplanes. My favorite part was actually the opening, where Langewiesche recounts and "translates" the subtext of the dry NTSB testimony; in a few short pages, a few sly, dry explications of what a pat reply to the investigative panel might really mean, WL lays out so much about the modern industry. This is the best kind of informed investigative journalism.
