I am not envisioning Mike Nelson sitting on the Med's bottom, sawing thru an 8-foot diameter cable with his diving knife. This article is, though. Perhaps Mike would do that. He could take down his new waterproof USB memory-stick, too. Use it on his Sony Vaio laptop with its built-in camera. Start up a Skype session, even. Then, back it all up to his waterproof USB stick.
That's not exactly what I envision saboteurs doing, though. I'm glad this article's writer have never heard of "explosive charge". Or perhaps bringing down 100 lbs of magnesium and some battery powered blasting cap device, and at least Mike's Skype session would have a kleig's lightshow available. Who needs an arc welder?
