REAL ending of Survivor
The end of Survivor isn't nearly so complicated. It's noted on page 7(8?) that a pile of valuable offerings has been left in the front of the passenger cabin. This pile includes a cassette recorder. Even before our hero starts to dictate his story -- during the few minutes he's supposed to be taking a piss -- he's actually in the bathroom dictating the last chapter into the cassette recorder. It's just ranting, nothing important plot-wise, and it can be interrupted at any point by the destruction of the plane. The minute the fourth engine flames out, he starts the cassette talking, then bails out, into Fertility's waiting arms (she's omniscient, you know). The rest of the book is just one machine whining and bitching to another machine. The crash will destroy the smaller recorder, but the surviving black box will make it appear that Tender is dead
