Members of the independent board investigating the Columbia disaster are getting a first-hand look at scattered debris. They arrived in East Texas this morning by helicopter from an Air Force Base in Louisiana.
The chairman of the commission says "it makes the accident more personal" for the experts as they conduct their work.
Searchers have been working since daylight this morning to recover more bits and pieces from the shuttle. They say they've recovered about 12-thousand fragments since they began searching for debris on Saturday -- including some human remains.
One of their largest finds so far has been the shuttle's nose cone. Officials say it's about five feet long and remains partially buried in a heavily wooded area in eastern Texas.
