Larger pieces of the shuttle will certainly be found. I was responding to a post asking about remains of the astronauts. I've done recovery on civilian aircraft that came down from about 10,000 feet. The shuttle was much higher and apparently involved an explosion and breakup before impact, so the dynamics of this are much different. In my experience, decent size pieces of the craft may be found, but the people are a different story. This isn't the thread for detailed discussion, so I was trying to give an idea without being too descriptive.
