A good ditching does always have an element of luck doesn't it? The fact that they all are alive is a great thing and the Cpt has obviously done a great job getting the aircraft on the water in one piece. The odds were significantly stacked against him. Night, poor wx, significant swell, maybe aircraft type too.
However lets hope at the end of this enquiry that the fuel regulations especially with regard to remote island opeartions are made far clearer!
Instigation of proper ditching training, not the fluffy box ticking crap that gets passed as training.
Great work to the locals who responded quickly at fetched them from the sea!!
