I'm not sure what the drama is about? This guy did a great job of saving some old airplanes, many of which would likely not exist now had he not built a big ass hangar and stored them. Think about it, WWII planes are pulled up from the Great Lakes and people are thrilled they are so well preserved. These planes likely could fly in months rather than years.
Let's face it, most of this collection is ME-109 copies and in the current collector market, real ME-109s aren't really all that popular. They're harder to fly, they're not as sexy looking and they are on the loosing side. No, whoever bought this collection did so for the parts, the Spitfire, the PBY stuff and lastly for the Buchons.
It seems clear to me that the guy in the story was in it initially for the sake of the planes and a future profit, then as a gift for his son, then just the money and that's it. I think these planes and parts did well to find this guy.
