    I have read a lot of interesting on the SRBs which really surprised me.
  First of all if one SRB is destroyed then both are. I think they send a
  signal to each but if one receives a destruct signal then it sends a
  signal to the other one incase the other SRB didn't recieve the orginal.
  (I my be wrong but that's what I remember the reporter saying.)
    Another interesting fact is that in the SRB the fuel is burning the
   entire length of the rocket. When they send a destruct signal to the
   SRBs it DOES NOT BLOW UP THE WHOLE THING!! I never realized this.
   What is does is blow off the top of the rocket. Now with the fuel
   burning the entire length it ends up burning at both ends. This
   stops the forward motion of the rocket and it falls to the ocean.
   If it survives the fall and they can find it, NASA will be able 
   to tell alot from it. As of Wed. Feb 5 NASA has said they think
   they found one of them but needs a closer look.
