The author's main point was that a moron like JFK Jr. can fly legally
(LEGALLY, that is the point!) with VFR at night in hazy conditions,
unsupervised. This is a fact

I don't think it's appropriate to disparage the deceased, I don't think
the guy was a moron - he just made a bad decision that had tragic
results.

As long as the visibility is 3 miles with a 1000' ceiling, yes you can
fly "unsupervised" at night. Few would attempt VFR flight in those
conditions, and that's where the poor judgement came into play.
