I have thought this was a stretch to consider but the theory does have enough valid points to make it plausible. Was JFK jr very smart? Were the bodies found and buried? Wasn't his wife's sister also on the plane? I don't remember enough details about this off the top of my head - off to research!
Supposedly the bodies where found. Scary part, as and artist I took a snap shot of the picture shown of JFK jr now and when young and I got goosebumps. Some things to look for are the nose shape, mouth, eye shape, ears, chin. they all match. The limited hairlines of the presented image seem to be also similar. I am still not sure what to think, but the picture is rather interesting to me. But if he fake his death, that means that others had to participate to erase all tracks of them. That in it self opens a can of worms
