Nah we don't need to shoot it down. Have President Bush fire up the same MHM (Mega Hurricane Modulator) he used in New Orleans just as the plane is about halfway over the Atlantic. Then have all Ahmadinnerjacket's wingnut allies here blame it on Global warming. He could even be eulogized by Al Gore.
Shoot 'im down just like we did with admiral Yamamoto in WW2!
