Apollo 11 Engines Underwater

An expedition funded and led by Amazon founder, Jeff Bezos, in 2013 is the reason the engines that propelled Neil Armstrong to the moon were found after so many decades. The discovery was components of two F-1 rocket engines.
These had been in the Atlantic Ocean for several years before the expedition caused them to be discovered again some days before the moon landing’s anniversary. Among the components discovered was a massive thrust chamber; it has the number 2044, NASA’s serial number for the F-1 engine stenciled in.
