Amazon founder Jeff Bezos announced Wednesday that his Bezos Expeditions team successfully recovered some of the remains of the F-1 engines that powered the Saturn V rocket, the workhorse of the Apollo lunar missions in the 1960s and 1970s. "We found so much. We've seen an underwater wonderland -- an incredible sculpture garden of twisted F-1 engines that tells the story of a fiery and violent end, one that serves testament to the Apollo program," Bezos wrote on his website Wednesday.
