The expedition to uncover the truth behind the disappearance of the French twin-engine flying boat “Latham 47” and the great Norwegian Polar explorer Roald Amundsen took place in the Barents Sea from the 24th of August to the 5th of September 2009. Despite several promising leads and an extensive search effort, it was not possible to produce tangible results. Rob McCallum, the expedition leader, explains the results as follows: “We have searched using all of the clues gathered over the last 10 years, including a public ‘open commission’ into the Latham’s disappearance. We have deployed some of the most advanced equipment in the world in our efforts to find the Latham. We can say definitively that the aircraft is not within these 35 sq miles of ocean, but we cannot say where it is.” McCallum is disappointed with the results, but he is thrilled to have been a part of an unforgettable experience. McCallum suggests two possibilities for the failure to find the Latham:
The first is that the data used could contain an error. The primary clue was a position report given in 1933 by the captain of a fishing vessel that snared a large piece of metallic debris. His position was given as both a depth and a bearing to Bear Island. It is entirely possible that with a rudimentary compass, a pitching vessel and the passage of 75 years, the information may have altered. The second, and very real possibility, is that the Latham was there, but has since been either removed from the site or completely destroyed by the massive amount of industrial fishing activity over the last decades. When watching the sonar data of the sea floor, the expedition crew rarely had a screen that was not criss-crossed by trawler drag-marks, and in much of the search area the scouring of the sea floor is complete.
Nevertheless the expedition members hailed the trip as a great adventure and were especially impressed by the efficiency of the crew aboard the ships HNoMS Tyr and CG Harstad.
The disappearance of the legendary polar explorer Roald Amundsen, his flying vessel the Latham 47 and his crew, however, still remains a mystery.
McCallum’s last blog post offers a few apt closing remarks: “It has been a privilege and a pleasure to work with the people involved in Operation Latham. Amundsen’s last days are an interesting story indeed and I am hoping that our research and our efforts can now provide a documentary that will tell this story of this iconic man and his brave crew that has waited far too long to be told.”
