The crash happened at 16:45 in Fog and darkness
Sunset was 16:11, ECT was 16:45 local time. Why the hell would you continue in conditions like this?
"It is unclear why he even attempted the last leg of the flight or attempted a landing in such difficult weather conditions. At the time of the accident around 4:45 p.m. it was not only darkness but also thick fog. According to various sources and based on recordings from the webcam, the visibility was only around 150 meters. If so, instrument flight conditions (IFR) would have existed."
