Apparently, Discovery channel is going to air a new series called "Cooper's Treasure," where, as best as I can determine, On Cooper's Mercury mission he was taking photographs, where he was apparently to look for missile sites, and some in the south Caribbean somehow or other showed evidence of treasure carrying shipwrecks. And supposedly he kept the pictures, poured over them for years in secret, and Cooper became like a father figure for the guy on the show, Darrell Miklos, and now he's looking for the sunken treasure.
I suppose we're obligated to point out how wrong it is. (Look for missile sites globally with a camera? Seriously? And as if he got to keep the camera and pictures anyway, if they existed in the first place.) (I suppose a first step is to see whether this guy was ever even in the same city as Cooper) My guess is, since the show doesn't actually require them to find anything, this guy is looking for a wreck using normal methods that actually exist (as in looking at sources), and made the whole space program story up to get on TV.
