Apollo 11 Engine recovered

As with everything Bezos, his discovery of an F-1 engine from Apollo 11 was held in deep secrecy. In 2012, he only briefly mentioned he found an engine, but didn't reveal any photos or the location. Only today, 1 year after the discovery & raising enough money to raise an engine did he release some obliquely angled photos of the engine.

The gubment & the voters did not have the money or the desire to recover the engine. Only the power of your purchases & the imagination of 1 man could get it done.

The generation which launched the engines believed it was the beginning of a new era of interplanetary exploration, discarding the engines forever, on the ocean floor. Only after the hindsight that human exploration beyond Earth orbit was over for good, did the next generation finally revisit an engine to recover it.

It was of course the huge demand for oil exploration that improved the underwater robot technology & sonar enough to discover & recover the engine. It would have been a lot harder & probably required a government budget, 14 years ago.

The engine was 1/2 a mile deeper than Titanic, it's parts broken off & strewn around the ocean floor.

The engine thrust chamber as seen on the sea floor, where it has rested ever since producing 1.5 million lbs of thrust for 150 seconds to push Niel Armstrong 42 miles off the ground & a speed of 6000 mph. The 356 braze welded tubes of the nozzle wall would have completely broken off from the heat of reentry & the impact with the ocean.

The braze welded nozzle, distorted from re-entry & impact.

Wall of the S-1C stage, completely decomposed. Similar decomposition happened to Saturn V hardware stored above ground, in the weather. The stage walls were made out of the absolute least amount of material.

The gas generator. Imagine the heat required to bend the pipes & the impact stress required to cleanly break off all the bolts attaching it to the fuel inlet.

The turbines which would have converted the searing hot 1500F gas generator exhaust to 55,000 horsepower of shaft power which would have pumped fuel. The peak of 1960's metal working technology is now corroded & desintegrated.

The combustion chamber, which held back the 6000F explosion of propellants at 65 times atmospheric pressure & transferred the engine's 1.5 million lbs of thrust to the rocket.

The injector which sprayed & mixed almost a million pounds of kerosine & oxygen into the combustion chamber.

Heat exchanger, which used gas generator exhaust to heat fresh oxygen before sending the gas generator exhaust back into the nozzle.

A hat band which held the braze welded nozzle together against the 1.5 millions lbs of exploding gas thrust.

Note how the force of re-entry blasted off all the nuts holding another section of pipe to the thrust chamber.

While Bezos didn't reveal the engine's location, it was probably several hundred miles east of Fl*rida, in a field with hundreds of spent rocket stages.
