KLM Flight 676

The aircraft involved was a Fokker F.XII named Leeuwerik, registered PH-AFL. It was built in 1929–1930 at the Fokker factory in Amsterdam and was part of a fleet of eight aircraft of the type operated by KLM. The aircraft type was developed as an improvement over the Fokker F.VII and was used on both European and long-distance routes. The aircraft was powered by three Pratt & Whitney Wasp C engines, each producing 425 horsepower. It had a cruising speed of approximately 205 km/h, a range of about 1,350 km, and a maximum takeoff weight of 7.2 tonnes. It could carry up to eight passengers on European routes. == Crew and passengers ==

at the KLM office on Leidseplein after the crash 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.. 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. == 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. == Aftermath ==

The crash caused widespread shock in the Netherlands, occurring shortly after the launch of the Amsterdam–Prague route. It followed closely after the crash with the Uiver, contributing to national mourning and concern about air travel safety. Due to these crashes, the KLM had in July a significant shortage of personnel and equipment. Soon after the disaster, though only after the first extensive reports about it had already been published, the German press authorities imposed a ban on publishing details of the accident. The victims were later transported to the Netherlands for burial. Most crew members were interred in a common grave at Zorgvlied cemetery in Amsterdam, while the passengers were buried separately. In 1967 a monument was placed, a Drenthe field stone with a bronze plaque. == References ==
