Lufthansa Cargo Flight 527 was a Lufthansa Cargo flight scheduled to fly from Rio de Janeiro in Brazil to Dakar, the capital of Senegal. On 26 July 1979, shortly after take-off in Rio, the Boeing 707 flew into a slope and crashed. All 3 crew members, consisting of the captain, the first officer, and a flight engineer died; there were no survivors. The principal cause of the crash was the failure of air traffic controllers to pay the necessary attention to each aircraft and ensure the necessary attention to rising terrain.
