It is a sad day for America.
There is no words that can express my personal feelings and my heart goes out to the families. I had awoken at 5am Hawaiian time to go to work and when I jumped in the car my heart missed a couple of beats when I heard it on the news on the radio.
With Columbia lost NASA will have to piece to together what happened. We will be inundated with reports and speculation. I am at a loss for words so I will close with this thought.
Americans have suffered through many National Losses and we will do as we have always done is pick up and carry on.
