Tangentially related, you might find the documentary "Out of the Clear Blue Sky" interesting. It's about bond trading firm Cantor Fitzgerald (headquartered on the top floors of the World Trade Center) in the days after 9/11. Not even the best plan could have helped them open for business in two days after having lost just about everything. Over the last decade or so we've put a lot of emphasis on documentation when it comes to incident response but the movie is really a testament to how leadership and execution are so much more important.
