A movie movie landing in the mist with little visibility

It is a movie that land in the mist with almost no visibility. Since the route is instructed from the control tower properly, it seems that there is no visibility because there is no sight, but when you look as a movie like this it will not look like you can land very much. Is he a professional skill?

The playback of the movie is from the following.
'City of Mist' landed at Heathrow Airport in London. By the way, the "foggy city" seems to be a name attached since smog often occurred during the Industrial Revolution, and it seems to have nothing to do with the fog of weather.

Furthermore, even if it says to landing in the fog, it is not that it is a veteran skill, but I got the Tsukkom that such technology was established. There is a category in the accuracy of the instrument landing gear (ILS), and in category IIIa it seems that it is possible to landing by precise intrusion landing with a runway viewing distance of 200 m and it can be landed by autopilot, although there are cases where the instrument landing without ILS is.

In the following linked article, it is explained in an easy-to-understand manner by using images.
