Its not as cut and dry as a simple CFIT.Not by any means.For many people,the jury remains out and always will.The accident can be interpreted and dissected in so many ways.Collins was PIC and the PIC must know where he is(thats one angle).The Company handed Collins a flightplan that differed considerably to the one he had been briefed on(there's another angle).And the CAA oversaw the whole sorry incident,making only one inspection flight,not demanding that Antarctic survival equipment was carried or whiteout briefings performed,and feebly acquiescing to the company's request to drop the previous-visit requirement(yet another).
