There’s a guy out there who thinks he has one. He claims that it wasn’t tile damage that destroyed the vehicle, but what he thinks is proof that it entered sideways.

Without even bothering to examine his fuzzy pictures that supposedly constitute his “proof,” I have to say, sorry, it doesn’t hold any water. Even ignoring his implausible theories about sensor failures and software glitches, the entry g-loads are such that a sideways entry would be immediately noticed by the crew, as would the direction of the earth motion, particularly for an experienced crew (there were several veterans on this flight). The seats aren’t designed to take loads in that direction at those levels. But the cockpit chatter indicates nothing abnormal until just shortly before breakup.
