This particular aircraft was disassembled when the Nazis seized the factory. The parts were moved to various locations in the area, after the liberation of France these were gathered together and reassembled into a complete aircraft. It flew for the first time in March of 1945, well after the Germans had gone. The plane was never in Nazi hands, so any claims/suggestions that the aircraft was used to transport Hitler from Narvik to Buenos Aires are as much a load of BS as everything else that they do. (It's rather telling that their recap of the story omits the word "French" as used to refer to the seaplane) After the war the plane was owned and operated by Air France. The DeGaulle government nationalized Air France and took over operations. So for what they're claiming took place to be true, it would mean that the French government knowingly allowed national resources to be used in aiding and abetting the flight of fugitive Nazis from justice. Does anyone really think that this would be allowed? That they would assist wanted criminals on a par with Klaus Barbie, the infamous Gestapo chief of Lyons, in getting away? Just ridiculous, but par for the course.
For what it's worth, I can't see where they would go from here in terms of the story. The show has never been about conducting any sort of legitimate investigation, it's about pushing a predetermined narrative for the purpose of ratings,/$$. They've spent three seasons gathering "evidence" to support that narrative and Baer found someone to give him the thumbs up, going out and looking for more isn't going to accomplish anything.
