	Also, they're counting on the new composite-case SRBs to get a decent
payload from Vandenberg. As reported recently in Aviation Leak, a test case
failed under internal hydraulic pressure at 1.2 of the design load. Problem
is, ultimate failure is supposed not to occur before 1.4 design pressure.
This suggests that not all the bugs in the manufacturing process have been
worked out yet. Some people may be happy about the extra time margin.
