@neauoire your post made me want to read up on this (thanks!) and it looks like the sabotage was done in shallower sections at just 50m. What a wild story.

@neauoire when I was a teen, we used to get jobs on gas exploartion lines, doing geological exploration. Lug gas. Swing a chain saw, haul explosives. I have enough knowledge to blow things up to make way for a pipline. But I've never dived below 50 and mostly not more than 30. But I like a challenge. And a navy seal in a weatsuit. Yummy ;-)
