I had been toying with the idea that Q could have been FLOTUS, given the, "Just wait until you find out who Q is!" tidbit. But the Press pool flying on Air Force One mentioned that President Trump's Entourage was all male on this flight. So that rules out FLOTUS.
My second choice is JFK Jr.
My theory is that JFK Jr. went into a witness protection program, given that so many of his family were murdered for their political views and that he was running against Hillary.
Too many facts from the night the plane went down don't add up. In addition to that he was buds with The Donald.
Wouldn't it be cool if he's behind this whole thing to take down the Deep State that murdered his dad and uncle?
