Retired aircraft carrier the USS Oriskany, a.k.a. The Mighty O, gets a second career as a reef on the ocean floor off the coast of Florida - the world's largest artificial reef. The process of converting the aircraft carrier to a reef involves removing layers of harmful materials and carefully rigging explosives to flood and sink the ship just so. Will it work? Yes! Within hours, new life attaches to the ship.
