I am sure you have all heard by now, Challenger exploded.

The early reports have it that one of the SRB's may have exploded.

The weather reports had been of very cold weather.  What are
the temperature cycling limits on the SRB's?  Could the chilling
on the pad followed by the heating of the outer layers (morning
warmth, aerodynamic heating, etc.) have caused a problem with the
SRB fuel?  Either chemical or physical  (fracturing or sepparation
from the container).

I can only wonder now, what does the future hold for the shuttle.
