Agreed that I overstated the case a bit, but only a bit.  Being careful with
the O-rings will not reduce risk to zero, but it will improve the odds a lot.
Yes, there were O-ring problems in favorable conditions, but the points on
the graphs cluster awfully heavily on the "unfavorable" side.

> ... It would be mad to launch an unfixed SRB with that kind of track record.

Not mad, just a little daring in a good cause.  There is no such thing as
a zero-risk mission.  Remember "if we die, we want the program to continue;
the conquest of space is worth the risk of life"?  The continuation of the
shuttle program is receding steadily farther into the future.

Sounds like a fine idea to me; pity it won't happen.

I do agree that flying the shuttle again immediately is unacceptable without
a firm commitment to replacing further losses.  That's the biggest reason
why, unfortunately, it's not going to happen.
