Engineers (or anybody involved in a botched product launch) may be interested in the story of the Vasa. It was a Swedish warship launched in 1627. At the time it was the most powerful warship in the world. It took many years to build at a shipyard in Stockholm within sight of the King's palace. The ship was launched at a public ceremony and made it 1300m out into the harbor. To fire a celebratory salute, its gunports were open. A strong wind came and tilted it over, letting water rush in through the gunports. It sank in minutes. The cause was poor design and a lack of appropriate ballast, rushed into production despite flaws. It sat at the bottom of the harbor for 300 years, perfectly preserved. In the 1970s, the Swedes decided to recover the ship by refloating it. It was a huge effort, but it worked. It has been completely restored and sits in a multi-story museum built around it. I saw it last month and was awestruck by the size and craftmanship. - https://en.wikipedia.org/wiki/Vasa_(ship)
