However many employees of Rocketdyne there may be still alive and kickin’, I doubt they ever imagined that their proudest achievement, the F-1 rocket engine that powered the Apollo Saturn V to the moon, would ever again be “in the news”. Thanks to Jeff Bezos, Amazon founder and CEO, a salvage operation is in the process of recovering bits and pieces of the F-1 engines that went into the briny deep when the Saturn V S1C stage was jettisoned after less than three minutes of flight. Why he’s doing this I have no idea, but the cynic in me wonders if he’s under contract to the Chinese because they have been unable to hack a blueprint of same. Nah!
National Review Online has a slide show with several pics of the F-1, both intact as well as some of the salvaged bits. And there’s a nice write-up with specs at Wikipedia. 
But the F-1 is best appreciated when seen in action. Several good clips are to be found at YouTube.
To get a better feel for the size of the F-1 engine and the booster, here’s a pic of a famous German rocket scientist standing at the business end of a Saturn V at the Johnson Space Center near Houston, TX.
To whet your appetite, here’s one of my favorites, in super slo-mo. Be sure to turn up your sound. The music makes it visceral. Credit for the clip goes to CEVOrion
