The point to ponder is that we really don't know why the
joint failed.  Did the cold have something to do with it?
Joints have suffered damage in warm weather.  Perhaps
increasing the leak test pressure to 200 psi?  Or maybe
the stretching of used booster segments?  Or something else
that hasn't been discovered?  Since we don't know, we can't
be confident the problem has been fixed.
