Terrible situation to be in. As to how they got there will be determined.
I think I would rather have attempted an on airport landing by descending on the VOR appch from a calculated VDP on the 3* appch path to below minimums to a lit runway as a last resort rather than attempt a night ditching in pitch black conditions in bad weather.
Assuming that is the type of appch they were doing???
Pelair's aircraft are not equipped to do the SCAT 1 appch???
Great to see all survived
