Top effort from the crew to salvage a diabolical situation.
However, I have to ask the question is this an why such an operation is permitted in the first place? I have never operated into Norfolk Island, however anecdotally I believe that it is a difficult destination due WX & its remote location.
I find it difficult to believe that to operate into a isolated aerodrome without an alternate is an appropriate for commercial operation, given that other possibilities exist (larger aircraft with greater fuel capacity).
Questions need to be asked of the operator & the regulator.
Here are the
METAR's for the 18th November.
