The Super DC-3's range was 1,900 nm, only slightly short of enough to
fly SFO-HNL (2,084 nm).  Given its 218 kts cruise speed, it would be
well over four hours away from land at mid-point.  Even assuming it
had the range, would you claim such a flight would not be dangerous?

Keep in mind the first case of a large airliner ditching involved a
Boeing 377 Stratocruiser, which had two engines fail near midpoint of
an LAX-HNL flight.  It's PW R-4360 Wasp radials were advanced (and
perhaps overstressed) versions of the R-1830 Wasps used on the DC-3.
(DC-3s also used Wright GR-1820 Cyclones.)

Yes, in that environment, a DC-3 would have been very dangerous.  A
modern jet, regardless of how many engines it has, is dangerous in
such an environment, too, though far less so than a DC-3.
