I worked at HLLT in the 60s and had the misfortune to be there when an airliner crashed. It was early morning, very quiet traffic-wise, weather good but some mist patches. Aircraft was on a fairly short flight with an experienced crew including a check-captain on the flight deck. A visual approach was made from some distance out but slant vis close-in caused a go-around. The pilot elected to make a visual circuit to the opposite end and crashed several miles short of the runway.
There was no problem with ATC or the airfield. There was no ILS but weather was usually good enough for visual approaches, which was the preferred approach for the majority of crews, whether based or not.
Many airfields around the world are not so well equipped as say JFK, CDG, Heathrow, etc., but they function quite normally with no problems, H24 365 days a year.
My thoughts are with the crew and pax who lost their lives and with the ATC staff who were on watch.
