Did somebody try to Wellstone Bush Senior?

My brother is very suspicious about the fatal crash of a private jet as it was landing in Houston to pick up Poppy and fly him to Ecuador.

I can't find, in a few minutes of googling, any good conspiracy theories out there--yet. I went to twa800.com to see if they had anything--all I found out was that Nelson DeMille has a new novel based on TWA 800.
