Tupolev ANT-4 (TB-1 & G-1)

Polyarnaya Aviatsiya

The crew was performing a flight from Kresty Kolymsky to Anadyr on behalf of the Chukotskaya Aviagruppa on this Tupolev G-1, a version of the ANT-4. The captain (M. N. Tomilin) decided to cut the route short when shortly later, he encountered below-minima weather conditions (poor visibility, snow and icing). Instead to return, he decided to continue in such conditions when the aircraft crash-landed in the foothills of the Pekulny range on the upper reaches of the Afonkin River, some 60 km east of Stalino (now Mukhomornaya). The aircraft was lost while all three crew members were slightly injured and rescued.

The pilot failed to cope with landing on the river Anadyr near Snezhnoye in 'mirror' conditions. The aircraft crashed into the water and came to rest in a depth of 8-9 meters. All four crew members were killed.

Dobrolet

The crew was performing a local test and control flight in preparation of the first flight between Moscow and New York. In flight, a technical failure forced the crew to attempt an emergency landing in the taiga. While both occupants were unhurt, the aircraft was damaged beyond repair.
