The networks like Discovery or the History Channel often have opined about this mystery or that, without adequate basis or evidence.
This documentary seemed different, and the NOVA series on PBS has a great reputation for quality, so I saw this one differently.
Although Lindbergh's political sympathies with Nazi eugenics was already well known, most of the world was not aware of the extremes of it for him. I've seen documentaries all my life about Lindbergh, but they never ever mentioned his second family and children, which were proven by DNA to be his in 2003.
If you've no time for hour-length video links, the gist of the accusation is that the Lindbergh boy had health issues that would have implied genetic inferiority for the very earnest eugenicist. The short version is that Charles Lindbergh hired the kidnappers to take his son, possibly with intent to have him secretly institutionalized. Otherwise, his offspring would have weakened the race, family name, etc.
It's by no means proven, but it is based on more than just salacious accusations. It is a bit jarring to go from hero worship of one of the most famous aviators and pioneers of the modern era, to a monster who could have orchestrated this ruse.
Even the experts on Lindbergh who don't ascribe to his involvement, reveal that he was a total control freak, which certainly fits with the personality profile required. The proven bigamy is clear indication that he was capable of the very darkest concealment possible.
What do you think? Sensationalized pap for some theorist/author wanting sales, or possibly credible?
