What happened
The incident involved an aircraft that was tasked with transporting two individuals: a pilot and a communication officer. The passenger, identified as Lieutenant Lebedev, was assigned to Stalingrad. Despite the planned itinerary, the airplane failed to reach its intended destination. Search efforts or subsequent investigations did not yield any physical evidence of the crash site or wreckage. Consequently, the aircraft and its occupants were classified as lost without trace.
Findings
Due to the complete absence of debris or other physical indicators, specific mechanical failures or environmental factors could not be definitively identified from the available records. The primary conclusion drawn from the disappearance is that the aircraft ceased operations during the flight phase leading to Stalingrad, with no further contact established thereafter.
