In the passenger-labeling picture at #266, BB claims he's "probably" the person seen along the starboard wing, who is more properly labeled as Flip Hollstein, claiming he's (as BB) bringing his wife (MB) a life jacket. Flip had no such extra life jacket with him, and moments after that frame was taken, is seen to swim rearward, never having reached proximity to Marilyn Briley. Yet Bruce was indeed keeping both life jackets that Marilyn would wear:
The regular adult life jacket BB's chest he has given to MB right about the time Fuddy has been replaced in the scenario by a diver and the other he gives to her just before they leave the plane area, as seen in post #385.
BB would have been able to recall this pre-planned choreography in his sleep, yet chooses to hide them falsely in his book's text. We may rest assured no innocent passenger had a life jacket attached to a foot-and-and a half long phallus in the plane. (Or would someone care to disagree?) These life jacket-swapping shenanigans (Fuddy, too?) are a hallmark of kind of deceit that was engaged in by these passengers. No such happenings would have found their place in an unrehearsed accident scenario!
Hence, these activities confirm the nature of a hoax.
