I must have had a bad link or they just changed the image as I can now see the superimposed uboat on the video link. That's what I had guessed they were looking at and it's a stretch of imagination I don't believe at all. Why go there? Did they get stuck inside the defenses and scuttle? No, the crew would have been found out. A snorkel means a late war boat and I find that even harder to swallow as a story.

This will prove to be something else and if it is a uboat, I would place it as a WW1 boat more likely.
