From the actual control room voice recorders at the time of the event on that
launch "expletive deleted solids" . Look it up.
Don't get me wrong, I manufacture a lot of solid rocket motors. From small to
sub-orbital, over 16K units last year.

Bill - where in that do you count liquid boosters that failed due to a
solid strap-on failure? I recall several such even without looking up
the records, which suggests this may be a statistically worthwhile
subcategory to break out.

The data set of all launches to orbit 1980 - 2010 shows solid rockets
having about 1/2 the failure rate of liquid rockets.

What is the failure rate for solid boosters if we
ignore BuSabInternal effects.
Hmm, stage trees.
