I remember from somewhere that all US manned space flights have lifted off
in a head-down position so the astronaut(s) could use the horizon as an
emergency backup attitude reference.

The previous almost-burnthrough of an SRB occured in the nozzle liner.
(A Morton-Thiokol spokesman, when questioned about that incident, claimed
that there were still 15-20 seconds of safety margin left.)  The right SRB
on the Challenger almost certainly failed much higher up.  Thus I suspect
the two problems are unrelated.

The above viewpoints are mine.  They are unrelated to
those of anyone else, including my cat and my employer.
