In the late 1700s, Thomas Jefferson wanted the United States to adopt a unified system of measurement and saw the metric system as the best solution. However, a pirate attack in the Caribbean disrupted these plans. Joseph Dombey, a French scientist carrying a kilogram and meter stick to demonstrate the metric system, was captured by pirates. By the time France sent another scientist to explain the system to the Americans, Jefferson was no longer in office, and plans to go metric were disregarded.
Also that NASA’s scientists with many suppliers would have performed their tasks and intended with quality, following through schedules. Through a handful of projects. Meaning that some space missions would not have failed. Those outcomes could have made us living and work on the Moon by now. (Maybe).
Great historic trivia. Have always wondered why the US had chosen their system. Still never to late to change over.
