Roald Amundsen Latham 47 An expedition of the Royal Norwegian Navy that set sail at the end of August south of the Svalbard archipelago did not succeed finding the wreckage of Amundsen's plane.

The explorer disappeared on June 18, 1928 when his aircraft, a Latham 47, went down while flying on a rescue mission for another explorer, the Italian Umberto Nobile returning from the North Pole.

During the two weeks of the mission, documented by the German production company ContextTV, the search focused on a 40 square mile area of the sea floor based on the position given in the last radio message from Amundsen. Situated northwest of the island of Bjornoya (Bear Island), this area is located 500 kilometers north of Norway.
