Nubian,
It is a difficult concept I suppose.
Folks burn to death following a crash in an aircraft without crash resistant fuel cells.
Folks drown in frigid waters due to improper safety harnesses.
Both are sight seeing flights.
That is eleven deaths or so in two crashes in what....a month or so?
Where do you think the Media, FAA, NTSB, Insurance Carriers, and Lawyers are going to be looking for explanations?
