I've never seen the fascination with wreck diving in person, it's better left to ROV's and video camera's and laser scanners. I've always felt creeped out when diving near wrecks that had crew onboard. I much prefer seeing the natural flora and fauna and that is far more interesting at shallower depths.
The deep ocean is a weird and fascinating place, but it's never somewhere I'd go and visit myself. I'll watch the video feed from the ROV from the comfort of a lovely stable support vessel.
What's shocking about this is that you can clearly see that other ROV's have got more recovery systems onboard than these guys seem to have had even though they had people onboard.
I've done lots of wreck diving. It is awesome.
