I made a Baby Countdown web page to answer some of the questions I was getting. I'll be updating in periodically, I hope...

Thanks for your words, my wife and I have commented several times today how good it is to know we have such good friends in the world. You can share this with those you know, if you wish.
We woke up with a phone call from one of our friends who was watching the news this morning. My work at NASA involves spacecraft re-entry for other vehicles besides the shuttle and I have also worked on analyzing entry breakups such as the Space Station Mir. I immediately recognized from the videos that we were seeing a breakup... and that the chance of the crew surviving was infintismal. It was not going to be a good day. I thought of the astronaut families that would have been excited and eager to see their loved ones arrive, and now never would. I tried to imagine what the last moments of the astronauts might have been like, and realized I really couldn't handle that right then. So my engineering mind took over.
The space shuttle should not have been visible from Dallas. It was too late in the morning, the sunlight too bright, to make out the shuttle or the usual plasma trail it leaves behind. Given that it was clearly visible was not a good sign -- breakup was probably already underway before the bright and large fragments were videotaped splintering away over DFW.
During and after breakup, each debris piece would create its own sonic boom until it slowed below the speed of sound. The reports from people on the ground of hearing a 'train-like rumbling' or several explosions was likely the effect of dozens or hundreds of overlapping supersonic booms being heard as the debris soared overhead.
Later that morning as we watched the news reports, I received a call to head in to work to perform some analysis work. A few of us were asked to estimate where debris may have fallen to help direct the emergency response teams and focus the search area. By the time we had that done, there were already reports of fragments in Nacodoches and other locations. It looks like our estimates were very close to what others were finding. By 2pm there was little else I could do today. So my wife and I went home.
As we sat at home I realized how nice it had been to be busy and working, instead of having a lot of time to dwell on the events of the day. It was the first time in my career that I had dealt with and observed something of this magnitude, and now that I think about it I was proud. Not of what I did, because it was but a small part, but of how the people at Johnson Space Center were responding: efficient and professional.
I'm proud to be a part of this team that can deal with unexpected situations, the team that is going to determine what happened, and the team that is going to find solutions and return Americans to space. The months ahead will be difficult and challenging, but they will be months with a purpose that I imagine few ever experience. Those I saw at NASA today felt great sorrow, but by no means felt disheartened. And hearing all of the thoughts and prayers from our family, friends, and even strangers steadies our resolve even further. I don't think I can ever express how much that means to us.
One of the experienced flight directors commented in a news conference this afternoon how it is events like this that really bring this country together and how it is too bad that we don't come together more often in times of happiness rather than in times of tragedy. I thought they were good words. I look forward to us all coming together again when the next crew launches from Florida for the skies above.
Thanks for writing me, hope you are faring well.
Gavin
