From the Wikipedia article

KLM Flight 676 was a scheduled international passenger flight operated by KLM that crashed on 6 April 1935 near Brilon, Germany. The aircraft, a Fokker F.XII named Leeuwerik (registration PH-AFL), flew into a mountain during a severe snowstorm and caught fire. All seven people on board were killed.

The crash occurred shortly after the opening of the Amsterdam–Prague air service and was one of several early fatal accidents of the KLM.

Accident

On 6 April 1935, the aircraft departed from Prague, Czechoslovakia for Rotterdam, the Netherlands with an intermediate stop at Halle-Leipzig. After departing the stopover at 13:14 local time, the aircraft encountered extremely poor weather conditions, including a heavy snowstorm, limited visibility of around 200 metres, and thunderstorms.

At 14:39, the pilot reported to Cologne radio station that he was retracting the antenna due to lightning. This was the last communication received from the aircraft..

Shortly afterward, the aircraft crashed into the Burgberg mountain near Brilon in the Sauerland region, approximately 80 kilometres east of Dortmund. The aircraft caught fire on impact and was completely destroyed. All seven occupants were killed.

Contemporary reports described how the aircraft was flying at low altitude in the snowstorm before striking the terrain. Witnesses reported hearing the engines and then a sudden impact followed by flames.

Investigation and cause

Cause

Initial reports suggested that ice accumulation on the wings may have caused the aircraft to lose altitude and crash into the mountain.

However, the official investigation by German authorities concluded that the aircraft had been flying too low for reasons that could not be definitively determined. The report suggested that the pilot may have descended to maintain visual contact with the ground in poor weather conditions. Other possible contributing factors included reduced engine performance or concerns about icing, but the exact cause was never established.
