Aerolíneas Argentinas Flight 670

The crash of Aerolíneas Argentinas Flight 670 was an accident involving a Douglas DC-4 of the Argentinian airline Aerolíneas Argentinas in San Carlos de Bolívar, Argentina on 8 December 1957, killing all 61 people on board.

Accident

Aerolíneas Argentinas Flight 670 took off from Ministro Pistarini International Airport in Buenos Aires, Argentina at 3.54 pm on 8 December 1957 on a scheduled flight to San Carlos de Bariloche International Airport in Bariloche, Argentina, carrying 6 crew and 55 passengers. ATC cleared Flight 670 for an IFR flight outside airways, at an altitude of 3937 ft towards Neuquen, with the remainder of the flight being cleared for 7874 ft.

However the aircraft only flew at a height of 328 ft to 492 ft for a distance of 35 to 40 km and thereby deviated 21 km from its intended course. The captain of Flight 670 executed this tactic in an effort to avoid an intense cold front by flying under it.

The captain ultimately flew the aircraft into the worsening storm at its most active part, and proceeded to climb sharply. At a height of 8202 ft, the aircraft's left wing failed, followed quickly by the tail section as it dove uncontrollably towards the ground.

At 4.45 pm, Flight 670 crashed 25 km Southeast of San Carlos de Bolívar at a descent angle of 35 degrees and a 25-degree left bank while going over 400 km/h. The aircraft was destroyed by the impact and post-crash fire. None of the plane's 61 occupants survived the crash.
