Prague - Zurich

While descending to Zurich-Kloten Airport, the flight engineer encountered technical issues with the cabine pressure and was forced to control it manually. Focused on this problem, he failed to hear and understand the instruction of the captain to lower the gear. In such circumstances, the airplane landed on its belly on runway 16 and slid for 875 meters before coming to rest in flames. All 20 occupants were quickly evacuated and uninjured while the aircraft was damaged beyond repair. Apparently, the crew failed to hear the gear alarm.
