A very sad accident as many have said, nothing else, except that there are many more consequences than with a 'normal' train accident.

And there is nothing unexpected about this tragic (or should it be 'pathetic'?) loss in a statistical sense. The numbers I have read are that NASA expects 1 total loss for 50 to 75 flights. So two losses on 113 flight are well within the limits of expectation. Though these considerations do not help at all the relations whose grief I can feel.
