Not all of them. Entertaining trivia: The Space Shuttle main tank was manufactured at the Michoud Assembly Facility, somewhere near New Orleans, and transported to KSC by barge. In 1995, the tug lost power and nearly lost the barge and tank, but both were rescued by another ship. Which then claimed 50% of the cost of the tank as salvage fees. Many lawyers were entertained and kept in Rice Krispies, but I don't remember what the bottom line turned out to be. https://www.orlandosentinel.com/news/os-xpm-1995-05-15-9505140385-story.html https://www.orlandosentinel.com/news/os-xpm-1995-05-15-95051... Ha! Found something... https://caselaw.findlaw.com/us-5th-circuit/1392461.html https://caselaw.findlaw.com/us-5th-circuit/1392461.html "'Twas a dark and very stormy night, November 14-15, 1994, and the situation looked bleak for the barge Poseidon. Caught in the clutches of Tropical Storm Gordon, Poseidon and her escort, the J.A. Orgeron, were without power and adrift. Driven on the gales of the tempest, the flotilla was swiftly approaching the Bethel Shoal; if they ran aground, the ships were sure to founder and be lost. Acutely aware of the danger, Orgeron's captain radioed for help. Alas, the Coast Guard was not in a position to mount a rescue. In despair, the captain made plans to release Poseidon and her valuable cargo, an external fuel tank for the space shuttle. Although this action would result in the certain loss of Poseidon and the tank, the captain hoped thereby to save Orgeron and her crew."
