In 1969, people across the world tuned into to watch Apollo 11 astronauts Neil Armstrong and Buzz Aldrin walk on the moon. The command module Columbia, in which the crew returned to Earth, is on show at the National Air and Space Museum in Washington DC, but what of the Saturn V rocket which blasted them into space?

In 2013, Amazon CEO Jeff Bezos paid a crew to salvage parts of two rocket engines from the bottom of the Atlantic. The rocket remains are worth an estimated $10 million. Bezos observed via his Bezos Expeditions website at the time: "We have seen an underwater wonderland – an incredible sculpture garden of twisted F-1 engines that tell the story of a fiery and violent end, one that serves testament to the Apollo program."
