According to Mar 3 AW&ST, the following changes may be made to the SRBs:
Add high strength bolts in the area of the 177 pins joining the segments
Catches similar to joints on the new composite SRB's
Changes in insulation putty
Improved O-ring seals, possible the .291 in diameter seals used in the
composite SRB's, permanently sealed.
External band heaters
According to Mulloy, there are 829 Criticality 1 items on the shuttle,
including 213 on the SRB system.
Could somebody from NASA post some of that list?
--------------< end of USENET note >------------
These make sense. I would not want to see a totally re-designed SRB seal
or casing. That would require going back to square 1 as far as testing
is concerned.

| They may not be going back to square one as far as testing is concerned, but
I'll bet they're going back to exhaustive testing/demonstration at square two!
