Although the resolution of the photo evidence is not very good, a large area of damage as purported by some NASA engineers is not evident at all. In fact, no damage is evident. No gleaming white surfaces that would indicate damaged tiles.
I am now more than ever convinced that the foam hitting the wing is a red herring.
Again I believe that something not yet considered, was the catalyst for the failure of the craft. Their are so many possibilities that it boggles the mind but, we must figure it out and soon.
The media is putting up a statement that the 30 seconds of data could not be retrieved by NASA. They are wrong, that is not what NASA said. What they said was the data was too corrupted to make any sense.
The evidence then, must be on the ground. IMHO
