This is terrible news. I have great respect for nasa and all their men and women. I hope they discover what happened quickly.
Not to make light of the subject, but the sts-107
patch appears to have a shooting star on it. Similar to the images of the shuttles demise.

http://spaceflight.nasa.gov/gallery/images/shuttle/sts-107/html/sts107-s-001.htmlThe seven stars (on patch) represent the mission crew members and honor the original astronauts who paved the way to make research in space possible. The constellation Columba (the dove(the seven stars)) was chosen to symbolize peace on Earth and the Space Shuttle Columbia.
With all Respect,
