I read that here, too, but I haven't heard anything about that in any of the news reports. James Cameron apparently has some good connections in the business, which he has contacted, and he said in a video that he posted on YouTube that communications were lost at the same time as the transponder stopped working and that the Navy picked up up a noise consistent with implosion more or less at the same time. I just hope for the sake of the people in the sub that there were no warning signs beforehand.
