There was a thread in here about a bb shell replacement where the owner of Franklin Frames was quoted as saying "young guys can't do this" or something like that. I'm not young, but I took that as a challenge. I wasted quite a bit of gas and time taking a bb shell off. It wasn't as bad as I thought, but I really wouldn't want to do it again. If I had to, I think I would want to set up some firebrick with a couple of torches going and then it might not be so bad.
The thing I think happened with OP's bike is the tube separated because of improper brazing and then the crack went into the bb shell. If it's possible for that to happen without cracking the tube, I'm not sure.
I went back and looked for previous threads and didn't find the most recent one I was thinking of. I don't think it's in C&V. Maybe.
