Cousteau:
Dynamite + Belize = Blue Hole
I thought this one was true, until a few minutes ago. Not that he created the blue hole with dynamite, as Doc's equality might suggest, but that he gained access for the Calypso by dynamiting the surrounding coral. Based on a couple of minutes of googling, I still think it might be true (unsubstantiated, they say), but now that I think about it, I don't recall seeing any obvious sign of it at the Blue Hole, at either mooring. Does anybody know?
It wouldn't surprise me, given some of the other things he did (dynamite fish survey, shark revenge killings etc)
I understand that the Cousteau expedition had previously admitted using dynamite on reefs in Belize, but refused to confirm or deny whether it was used in or around the Blue Hole. My best guess is: elements of truth, but probably exaggerated.
Curiously, when I was in Truk Lagoon the captain of the Odyssey hinted darkly that Cousteau still had a very bad reputation in Truk from the time he raided all the old wrecks, but he refused to elaborate on why it was still felt keenly.
Personally, I always thought Cousteau was a bit of a prick (not simply because he is French, but that clearly doesn't help). But I can't swear to the truth of the various rumours.
