A number of posts as well as the report mention the crew could have done an Autoland in the low vis conditions. Whilst it might be an absolute last resort option it carries a large risk.
There is a very good reason why an airport is only classified Cat 1 and not Cat 2/3. It is not a "free get out of jail card" as many pilots seem to think. It has a large risk associated with it, namely it is not guaranteed to deliver the aircraft to the correct position on the runway.
Australia is about the only country that I am aware of that allows "practice autolands" to Cat 1 runways. It was not permitted when I was operating O/S. All autolands in whatever met conditions were only permitted on certified Cat 2/3 runways.
