I have great faith in both Tighar and your sonar anomaly Richie. It is a logical step to get back there and check quite a few things and, hopefully pick something up that isn't 'coral'. Once that is achieved and, the result is found to be positive, then the real work begins.
Yes, it's a tragedy we all find ourselves in the current situation and, I still hold out for a sensible compromise but, it shouldn't deter the continued efforts being made by everyone here.
I'm all for offering options which will halt the current situation from continuing. I like the offer Ric made but, do not want the 2010 ROV to continue to focus on 'aircraft wreckage' rather, it would be more useful if it was studied from a marine biology point of view instead. Sometimes a different approach to the same problem can bring a clearer understanding of things.
