A DC-3 aircraft, registration OK-WDK, experienced a significant incident during a cargo flight from Prague to Brno and Bratislava-Ivanka. The flight began uneventfully, with communication established with Bratislava at 22:42. Upon approaching the runway, the aircraft impacted a wooded hillside approximately 14.5 km from the threshold. A fire erupted, originating from blocked pitot tubes due to inclement weather conditions ? specifically, reduced visibility and overcast skies. Incorrect altimeter readings resulted in the crew descending to 70 meters above the airfield elevation, deviating from the intended altitude of 600 meters.A DC-3 aircraft, registration OK-WDK, experienced a significant incident during a cargo flight from Prague to Brno and Bratislava-Ivanka.
