What happened
Shortly after departing from Lisbon-Portela de Sacavém Airport, a four-engine aircraft experienced a loss of control during its initial climb. The aircraft drifted off course and impacted the ocean surface a few kilometers away from the coastline.
The flight was operating as a repatriation mission, transporting the remains of Brazilian military personnel who had died during the Second World War back to Brazil. During the descent into the water, the impact resulted in eight fatalities, accounting for all crew members on board.
Findings
Following the departure from the Lisbon area, the aircraft became uncontrollable during the climb phase, leading to the fatal crash into the sea.
