By the time I got out of training, the news cycle had moved on so it wasn't until the first anniversary of 9/11 that I saw the news footage of the event for the first time.
Coincidentally I ended up stationed in Washington, D.C. and from my barracks I could see the construction cranes working on the damage to the Pentagon.
So it's this weird combination of feeling connected since I was in the military when it happened and then lived near one of the sites, but I also missed a lot. This site could help me see some of the experience I missed.
