I Quote The Enemy:
The second theory for the virtual disappearance of 269 people from the site of the crash is suggested by Soviet correspondent Andrey Illesh in his book, The Mystery of Korean Boeing 747. This theory proposes that the bodies were eaten by giant crabs. There is even a picture of one of those crabs that supposedly populate the sea bottom where KAL 007 finally came to rest.
The crab theory has been persistent and been echoed by the Soviet interceptor pilot Gennadie Osipovich himself (though evidently not with full conviction).
“…I heard that they had found the ‘Boeing’ when I was still on Sakhalin. And even investigated it. But no one saw people there. I, however, explain that by the fact that there are crabs in the sea off Sakhalin that immediately devour everything… I did hear that they found only a hand in a black glove. Perhaps it was the hand of the pilot of the aircraft that I shot down. You know, even now I cannot really believe that there were passengers on board. You cannot write off everyone to the crabs… Surely something would be left?… Nevertheless, I am a supporter of the old version: It was a spy plane. In any event, it was not happenstance that it flew towards us.”
Professor William Newman, marine biologist, explains why the crab (or any other sea creature) theory is untenable: “Even if we proceed from the supposition that crustaceans, or sharks, or something else fell upon the flesh, the skeletons should have remained. In many cases, skeletons were found on the sea or ocean floor, which had sat there for many years and, even decades. In addition, the crustaceans would not have touched bones.”
In addition, the crab theory could not account for the lack of luggage.
