2) With regard to 51-L: Didn't it turn out that there was enough of a
chamber pressure differential between the left and right SRB where a
problem could have been detected had that system been monitored in real
time during launch (as I recall, the chamber pressures were being
recorded, but not monitored in real time)?

Yes, but a better parameter to look at would have been the gimbal angles
of the SSMEs and SRBs. When compared to the expected gimbal angles, it was
really evident that something was wrong. And, this occurred earlier and
was a larger change than the chamber pressures.

On Columbia, the same could be said about the "gimbel" or deflections of
the aerosurfaces. They too, when compared to the expected deflection
diverged radically.

If the controls are diverging radically from what is expected, something
is seriously wrong.
