very plausible, given the lack of evidence to the contrary.
i'd just like to add that i think there is also a part you left out, where after 6 months, a Swedish backpacker, who is authoring a highly popular "Adventure Mystery Travel" blog, buys a ticket to Diego Garcia off a ladyboy in Thailand who is trying to raise money for his/her operation (but that's another story, and the subject of a critically acclaimed spin-off series by HBO), and whilst trekking through the jungle there, accidentally stumbles across the buried evidence, and is about to make an entry on Twitter announcing his revelation to the whole world, when all of the sudden he is murdered in cold blood by a private mercenary on leave from Iraq and doing freelance work for the South East Asian chapter of the Rosicrucian society (also the subject of a spin-off 3 part movie).
