Very interesting read

Hard to think about what else might be down there,

Apart from the lives that were lost, imagine the amount of equipment, amunition and other things that scatter the sea bed around normandy, having been there with the rally, its amazing to think you literally only see the tip of the iceberg

5m is snorkel depth, almost too shallow for scuba. Seems strange that they have used all this kit and money to image something so shallow.

Even so, still amazing what's down there. Makes me regret giving up diving

Great bit of British engineering.
