I was recently on a History Channel shoot on this very wreck (to be aired in Nov 2008 - Lost Cities of the Underworld) and during the pre-filming one of the members of the film crew actually tried to wrestle one of those Mark IX depth charges around and pull it out. One of the advisor divers saw this and very quickly put an end to that but there were some hands on it at some point. These particular depth charges holds about 300lbs of HE each.
