History
Interesting to read about 2 relatively recent cases of use of autoland during fog in Australia.
More than 20 years ago, during interesting conversations with Australian pilots in our company, exactly this kind of "legality and wisdom" matters were the subject.
The Ozzies then already described a case of a crew being caught by fog at Sydney - and they were a crew not (yet) qualified for Low Visibility autoland. So, they considered themselves to be legally not allowed to land, only alternative was to ditch, perhaps in Syney harbour, were the fog did not reach. Some smartass suggested over the radio "how legal do you think that ditching would be?" The crew then decided after all to go ahead with the autoland.
Have never been sure whether it was a 100% real story, or more of a saga to teach airmanship - well, here is documented proof that it happened more than once in years since back then.
