According to the Rogers commission, "O-ring thermal distress" has occurred
during launches in temperatures as high as 75 deg F (STS-61A, two different
joints). Anomalies also occurred on STS-41D and STS-2, which were both
launched at 70 F, despite a lower leak check pressure (100 psi on the nozzle
joint on 41D, 50 psi on STS-2).  It would be mad to launch an unfixed SRB
with that kind of track record.

Perhaps I'd approve of a military flight of an unmodified shuttle if the DoD
FIRST turned over its SDI funding for a year and built another orbiter (and
possibly another launch pad) to cover NASA in the event of another disaster.
Unfortunately, though, it's always NASA who gets to eat the risks.
