I am fascinated by giant machinery. Big gears doing big things and big drills digging big holes and big structures dwarfed by even bigger ships. This video has it all. Watch as this 14,000 ton
(yep, that's not a typo) oil rig gets decommissioned and brought back to shore leaving only those poor little legs behind in the middle of the sea.
PS: What if a ship runs into those leftover legs in the future?
