Sikorsky S-38

One hour after his departure from Shanghai, while overflying the Bay of Hangzhou, the crew encountered foggy conditions and informed his base he was returning to Shanghai. A brief message was transmitted with two audible words 'turning back'. Shortly later, the seaplane crashed in the Bay of Hangzhou, south of Shanghai. Some debris were found 10 days later and the dead body of the captain was found four months later. The passenger was a Japanese citizen.

Named 'Von Krohn', the seaplane aircraft was on its way from Quibdó to Cartago, in the province of Valle del Cauca. The crew maintained radio contact till 1055LT. Five minutes later, the aircraft impacted a mountain slope in the region of El Águila. SAR arrived on the scene two weeks later only because the aircraft crashed in an isolated and unreachable area. The passenger J. C. Zúniga Angel and the mechanic Haucke Notz were found dead in the cabin while the pilot Hans-Walter Geck and the radio operator Ernst Jahnke were found dead few km from the main wreckage. They probably walked away to find help but they died en route. Eventually, the passenger N. C. Marshall was found alive near the wreckage and later evacuated to a local hospital.

On approach to Hangzhou, the crew reduced his altitude due to low visibility caused by foggy conditions. As the Captain was unable to locate the landing area in the Hangzhou Bay, he initiated a go around procedure. During the last turn, while flying too low, the float plane impacted a hill and crashed. All 11 occupants were injured and the aircraft was destroyed.

The seaplane departed March AFB on a flight to San Diego-Rockwell Field. While cruising at an altitude of 3,000 feet, the airplane suffered a structural failure. It entered an uncontrolled descent and crashed in a pasture in Oceanside. The aircraft was totally destroyed by impact forces and all seven crew members were killed.

The aircraft departed Chicago-Palwaukee in the early afternoon to complete a sightseeing tour over the Lake Michigan. While returning to his base, the crew decided to land on Lake Michigan in the harbor of Chicago. Due to strong winds, the lake was rough and the float plane hit violently the water surface. Consequently, the captain decided to abort the landing, increased engine power and elected to divert to Palwaukee Airport in Chicago. Shortly later, while climbing to a height of 600 feet, the aircraft lost its right wing and dove into the ground in a huge explosion. All nine occupants were killed.

Crashed in unknown circumstances somewhere in Colombia. The exact date of the mishap remains unknown, somewhere in 1932. The airplane was named 'Ernesto Cortissoz'.

While parked in the hangar of the company, the float plane was stolen by three men who took a fourth people as an hostage. Few minutes after takeoff, the aircraft went out of control and crashed in São João de Meriti, in the suburb of Rio de Janeiro, bursting into flames. All four occupants were killed. Brazilian authorities stated that the hijack took place during the Constitutional Revolution.

Owned by the American Lt Colonel George R. Hutchinson, the seaplane was on its way from New York to London on a private and nonstop transatlantic flight with seven passengers and a crew of two on board. En route, the crew encountered snow falls and the aircraft was too heavy due to snow accumulation. The pilot attempted an emergency landing off the Greenland coast but after landing, the airplane struck an iceberg and was seriously damaged. Several distress calls were sent but the aircraft moved on rough seas. The aircraft was eventually localized by the crew of the British fishing trawler named 'Lord Talbot' on September 18, five days after the accident, some 40 miles southwest of Angmagssalik (Tasiilaq). All nine occupants were rescued and repatriated to Europe. Lt Colonel Hutchinson was travelling with his wife Blanche and his two girls, Kathryn (8) and Janet Lee (6). The aircraft was lost and abandoned as a wing was torn off.
