NASA and 9/11

As I'm a photographer (as most of you know) Photographs to me hold a variety of different emotions, but this one that NASA captured on 09.11.2001 make chills run down my spine. It's a wonderful image, but also shows a very sad time in our countries history. Below is the photo, but I've also attached the link to NASA's website that has the image and a short blurb about it.
