I expect that there are certain tiles that are more critical than others - perhaps it was one of these that was hit.

One theory I heard this morning is being investigated is that the "foam" may have hit a left side wheel well cover, damaging its seal, which could have let heat into the well during re-entry. One of the first sensors to go out was at that location.

BTW, I also heard a report that the "foam" when hardened has the consistency of a brick.

I've speculated that -- is there a news or NASA source on it?
