Atlantic Ocean

Named 'Croix du Sud', the aircraft was performing its 25th cross Atlantic flight from France to South America. The trip was officially from Marseille to Rio de Janeiro with two intermediate stops in Dakar and Natal. Less than one hour after it left Dakar, the crew confirmed by radio he was encountering a technical problem with the rear right engine and that he was returning to Dakar. Several controls were made on this engine but an oil leak was detected and the engine must be changed. As no spare engine was available, the crew made a complete thorough cleaning and took off again from Dakar at 0643LT. Four hours later, the radio navigator sent a brief message 'we shut down the rear right engine'. This was the last message received by ground. Important SAR operations were initiated but no trace of the aircraft nor the five crew members was ever found. Among the crew was the famous French aviator and pioneer Jean Mermoz.

The American and Polish Aviator Stanley Hausner (Stanisłas Hausner) was attempting the first solo and nonstop transatlantic flight from New York to Warsaw, Poland. With 525 gallons of fuel and 25 gallons of oil on board, the aircraft departed Floyd Bennett Field in New York at 0946LT on June 3. A day later, while cruising over the North Atlantic Ocean, the pilot encountered technical problems with the fuel system. As the fuel was leaking, he was unable to continue the flight and decided to ditch the aircraft some 1,000 km west of the European coast. As he was not equipped with a radio, he could not send any distress call. A week later, on June 11, the crew of the Belgian ship named 'Circle Shell' spotted the aircraft floating with the pilot still alive and awaiting on a wing. The pilot was rescued and later repatriated to Europe while the aircraft sank and was lost.

Registered I-DONA, the Savoia-Marchetti S.55TA was taking part to a huge international rally organized by the Italian General Italo Balbo on a trip from Italy (Orbetello) to Brazil (Rio de Janeiro). A total of 14 Savoia-Marchetti S.55TA were involved in this rally. The group departed Orbetello on 17DEC1930, arrived in Kenitra on 21DEC1930, Villa Cisneros on 23DEC1930 and finally Bolama (Guinea Bissau, ex Portuguese Guinea) on Christmas Day. Due to poor weather conditions, it was not possible to continue so all crews observed a rest time on Bolama Island till 06JAN1931. This day, crew left Bolama without problems and continued along the route to Natal, some 3,000 km in total. At a distance of approximately 1,000 km off the Brazilian coast, crew encountered technical problems and attempted to make an emergency landing into the ocean. Several ships of the Italian Navy were cruising along the route, so all four crew were quickly rescued while the aircraft sunk and was lost. It was registered I-DONA, referring to the name of its captain Renato Donadelli.
