I'm not a technical expert where shuttle construction is concerned, but
I have some doubts that O-ring burnthrough was the primary cause of the blowup.
I'm recalling the "puff of black smoke" we saw on the launch pad at the 
time of ignition. There wasn't time for any kind of burnthrough then; the
nature of the "puff" indicated that something BLEW OUT, like a cap or plug
of some sort. This might support the idea of a crack in the propellant, eh?
