After reading some of the transcripts from the "Last Words" website,
where the flight engineers were dumping fuel when it became evident
that an emergecy landing was a certainty, it dawned on me that there
might be some benefit for a small plane as well. The less energy you
carry into a crash landing the better off you're going to be.

I think I'd prefer to maximise the chances of keeping all the
remaining fuel safely in the tanks after landing. My view is that any
reduction in landing weight is more than offset by the chances of
having fuel still in the dump system on landing and making fire more
likely.
