True enough...but I still think it should have been able to handle the
loss of the rig above.

What makes you think it wasn't designed to do so? The point you seem to
be missing is that the blowout preventer did not work the way it was
supposed to work, and while one can speculate forever about the reason,
we won't _know_ the reason until they get the well closed off and
recover the non-functional preventer.
