-for the second time in nasa s history, a space shuttle has been lost along with its entire crew. once again, we are asking ourselves, how could this have happened? -do you have any idea how big that piece of foam was that came off? -we d heard some reports that during launch there had been some concerns that some debris hit the wing. is that true and is that any cause of concern and that could have caused today s problems? -it is true. it was judged that, erm , that event did not represent a safety concern. -this happened under my watch, but i didn t have the answers. in every public forum i m gonna have to be in, how am i gonna explain this to anybody? at this time, we have no indication that the mishap was caused by anything or anyone on the ground. -nasa never wants to look stupid. nasa wants to be the agency with the answers. -my thoughts are on what we missed, what i missed to allow this to happen. -but if you overlook something, it will come to bite you one day or anot
all of that data pointed to a problem at rcc panel 8. something very different happened in this location on the orbiter. and so, let s go see if we can understand what that was. -ok, so, as the vehicle is entering the atmosphere, these black tiles are protecting the structure, the aluminium of the vehicle, in high-heat areas. and the grey is the wing leading edge reinforced carbon-carbon, rcc panels. those protect the vehicle from the highest level of heat, those 3,000 degree temperatures, so that you don t get metal melting. but we had never had any experience in breaking a panel.
And if you follow the logic, you begin to see pieces that are telling you a story. As we were progressing through the leftwing reconstruction, you can see these burned tiles, this reinforced carboncarbon, looks like its been burned in a way thats very different than everything else.
