(Air Florida accident)
Icing in the engines disabled some sensors, and the pilots thought
they were developing much higher power than they really did. I recall
reading that the accident was avoidable - had they recognized what was
wrong and pushed the throttles forward...

I read that report not long ago, so I happen to remember the details:

Mistake 1: They used reverse thrust for push-back on ground. This was
against a clear company policy. Doing so, they sucked a lot of snow into
the engines.

Mistake 2: They forgot to engage the de-ice system of the engines. This
resulted in clogged probes, resulting in wrong power readings. (The
instruments showed much more power than the engines actually delivered.)

Mistake 3: The copilot realized during the take-off run that there was
not enough power. The captain ignored his warnings and continued the
take-off. He also ignored the fact that the take-off run needed 800
meters more than expected.
