Theory!!!!
As JFKJr was flying his plane, which is suprising, b/c I figured that a spoiled, parasitic yuppie such as that would be flying first class- sipping wine, getting his dick sucked, and his nuts shaved aboard a jumbo jet from Newark to Boston. Anyway as he was flying his Piper, a big piece a bird shit shaped like a giant Mr. Hankey flew into his windshield. He couldn't get it off, despite the fact that he watches Southpark and worships the character Mr.Hankey!!!
Like a dumbass, he quickly becomes infatuated with the pile shit on the windshield and starts to yell "HeidiHOOOO." The plane looses altitude, and he ignores the radio. While flying his wife, Carolyn, does not know what's wrong with his husband. She thinks that he is a whole another person. She tries to snap him out of the "Mr. Hankey" spell, but couldn't!!! Yet, suddenly, John John gets horny and wants some airborne pussy from his wife. She tries to get back but John John quickly ignores the controls so he could get some tail for his little impotent willie. While Carolyn tries to fight off the "Mr. Hankey" crazed lunatic, her sister unsuccessfully tries to fight him off as well.
In the process, John John knocks his sister-in-law out cold, and gets to work on his submissive wife while staring glamorously at "Mr. Hankey" on the windshield. Noting that he couldn't get his rock hard, and his wife is weakily kicking and screaming as she is being raped, John John notices that his altimeter is spinning out of control like a weather vane in an Oklahoma tornado situation.
In a quick flash, John John gets off of his fatigued wife and gets to the controls and before you know it, John John, Carolyn, and his sister-in-law meets the horizon. Before they hit the water, John John yells out, "Oh God, Damn You Mr. Hankey."
Thinks to the "Mr. Hankey" birdshit and John John's infatuation with the insufferable, lovable, nasty Southpark cartoon character, America mourns a spoiled, pampered, overrated, parasitic, unimportant, non-political nobody by the name of the son of the slain 35th president, John F. Kennedy, Jr.
