The richest man in the world, Jeff Bezos, spent three weeks on a submarine in 2013 collecting the booster rockets used in the Apollo 11 mission from the ocean floor.
“I was five years old when I watched Apollo 11 unfold on television, and without any doubt it was a big contributor to my passions for science, engineering, and exploration,” Bezos – who has a net worth of $165.6 billion – wrote on the Bezos Expeditions blog in 2013. “A year or so ago, I started to wonder, with the right team of undersea pros, could we find and potentially recover the F-1 engines that started mankind’s mission to the moon?”
One of the rockets has been on display at The Museum of Flight in Seattle since 2015, according to the Museum’s website.
