The updated version of Inside 9/11, the National Geographic Channel's Emmy-nominated documentary, is being re-broadcast on March 25 at 7:00 p.m. Since the original four-hour miniseries first aired, new details about the tragedy have sprung up, including the trial of Zacarias Moussaoui; information on Able Danger, the intelligence team assigned to track al Qaeda; new video of the attack on the Pentagon; audio from Flight 93; the CIA's dismantling of the bin Laden unit; the death of Abu Musab al-Zarqawi; and new video from bin Laden himself.

It's been over five years since the events of September 11, 2001, and I can understand how some might be sick of hearing about it, but it's not surprising that the aftershocks of an event of this magnitude would still be felt even today. I'd like to think my ongoing curiosity is natural and not morbid, but I still want to learn as much as I can about everything that happened that day, and the people and events it connects to.
