Accident

Aeroflot Flight SU99 took off from Leningrad-Pulkovo Airport at 14:21. The flight went smoothly during takeoff and cruise. However, during the descent towards Murmansk, weather had deteriorated with cumulonimbus clouds at 260 meters, snow and visibility of 1.5 km. During the approach, 7.1 km from the runway, the Tupolev was flying 400 m to the left of the extended centreline. About 2400 m from the runway, the aircraft entered a snowstorm. The pilots descended below the glidepath for some reason. To make matters worse, the pilots noticed neighbourhood lighting on the ground near the middle marker. This caused the pilots to mistake them for runway lights and increase their rate of descent. When the pilots noticed the mistake, it was too late and the aircraft crashed onto the frozen Lake Kilp-Yavr. After hitting the ice the aircraft lost the left wing, and the fuselage broke in two, separating the cockpit. The right wing then separated. The fuselage stopped on the ice 1562 m from the beginning of the runway, and quickly sank. Soldiers managed to save several passengers from the sunken fuselage. The cockpit stopped on the ice 166 m to the left of the fuselage and also fell through the ice in shallow waters near a small island in the middle of the lake. It sank partially. All crew members, except the navigator, managed to escape.
