Hi Jenn!
Hmmm, I don't really know more than you but i've seen some TV specials too and I've been trying to understand but see my point:
Carpathia only stood some time more to see if there was any more boats or if someone appear bouncing in something. No one did and they have left only with some bodies with it. Then
Carpathia went to New York and took a week to reach it so... only one week later other boats went to the place with the point of getting bodies of passengers and crew of the Titanic. All the others ships that pass over the area just look a little bit and then they've continue their voyage. So, one week later most of the bodies went down with the heigth of the ice and of the body itself. Now, when Titanic was discovered in 1984, the bodies that were under water and could be reached had already dissapeared because of all the fishes and everything, but things like a pair of boots have reached our days.
They once explained that those boods were made of something that wouldn't dissapear ever only if the sand burrie them.
So this is way I think that no one was found under there, they were all "eaten" by the sea creatures or the sand as buried them forever... on their own grave!
This is how I want to believe things, but I may be wrong! Sorry for a so long letter and for the bad english!
