OK. BTW, the C141 had autoland but the Avro Vulcan was the first 4 engined aircraft to make a fully automatic landing in 1959. The difference between the military's application and the civilian one is that the military use of autoland was not primarily for fog but to lessen the load on the crew in combat conditions - a lesson learned by most civilian crews in the "combat" of busy TMAs!!
The Trident had the first system designed for civil transport use and the aircraft made the first fully automatic airliner landing, the first CAT3 landing and CAT3A landing, both on test and with fare paying passengers under real conditions.
Ray, you are right about CAT2, as I stated in an earlier post but, in the context of the late 1960s, CAT2 blind landings in fog were almost miraculous. Autoland saved BEA many diversions and won them passengers due to the likelihood of arriving at the intended destination.
In the days when dozens of flights were diverted from Heathrow each winter due to fog, there were very few days after the system was certificated when Tridents could be seen diverting to MAN, BHX, GLA etc. whilst their competitors were having to bus and train passengers from their diversion airports
