September 2009 might have been one of those dates etched in our history. That is when al Qaeda terrorists planned to walk onto New York City subway trains and into Grand Central Terminal with bombs in their backpacks. Those trains are ridden by more than 5 million people each day.

These notes are the handwritten recipe for bombs Najibullah Zazi hoped to explode on New York subway trains. The nine pages of instructions were written by Zazi in 2008, after he attended al Qaeda training classes in Pakistan.
