From the Wikipedia article
Aeroflot Flight 9 (flight number: SU9, callsign: AEROFLOT 9) was a Soviet domestic scheduled flight operated by Aeroflot from Irkutsk to Chita. On 14 October 1953, an Ilyushin Il-12P crashed on this flight immediately after takeoff from Irkutsk Airport. Four of the 28 occupants on board the aircraft were killed in the accident.
Sequence of the accident
About 50 to 60 seconds after takeoff and on reaching an altitude of about 100 to 120 metres, the captain reported by radio: "Что там у вас? – вижу встречный самолет!" ("What is that there? I see an oncoming aircraft!"). The air traffic controller still asked "Где видите встречный самолет?" ("Where do you see the oncoming aircraft?"), but received no further reply. The next moment, the captain flew a sharp right turn during which he lost control of the aircraft. The aircraft rolled to the right and crashed to the ground 2.5 kilometres beyond the runway and 500 metres to the right of the extended runway centreline.
Investigation and cause
Cause
The accident investigation revealed that at the time of the accident there had been no other aircraft in the surrounding airspace. The captain had misinterpreted the lights of the inner marker, located four kilometres from the runway, as the lights of an approaching aircraft and had made excessive control inputs to avoid a collision he feared. In this way, the loss of control and the crash of the aircraft occurred.
