So you are a bad guy planning to off Fuddy. You know the plane route. You have to get the pilot to put it down in the water and some kind of malfunction passing the NTSB investigation as no tampering. You have to know if she can swim or not. Then you have to get her lifevest replaced (pilot does it) cuz Hawaii water is warm and easy to float in. Or you have to get a second guy on the plane to cut her vest. Or a bent SEAL waiting underwater at the spot GPS selected. Already too complicated. Or is it? Investigation of pilots NTSB report and passengers should be thorough.
