It’s one of these very engines.

From the Wikipedia:

The F-1 burned 3,945 pounds (1,789 kg) of liquid oxygen and 1,738 pounds (788 kg) of RP-1 each second, generating 1,500,000 pounds-force (6.7 MN) of thrust. This equated to a flow rate of 413.5 US gallons (1,565 l) of LOX and 257.9 US gallons (976 l) RP-1 per second. During their two and a half minutes of operation, the five F-1s propelled the Saturn V vehicle to a height of 42 miles (68 km) and a speed of 6,164 miles per hour (9,920 km/h). The combined propellant flow rate of the five F-1s in the Saturn V was 3,357 US gallons (12,710 l) per second.^[5] Each F-1 engine had more thrust than three Space Shuttle Main Engines combined.^[6]

I've been on an Apollo kick myself for the last week or so. Watching everything I could on YouTube from that time. Here's the video that got me started.

That was such a wonderful time for me, as an American teenager (the summer between eighth and ninth grade). Listening to these conversations brings so much of it back.

One thing I noticed: the hum. In all the audio recordings of Apollo-Houston conversations, there's a deep, ever-present hum that's not quite at the limit of audibility.

What struck me is that you would never hear that hum today; the reason is because all communications channels - including voice - would be digital in our time. Back then, they were analog. When you remember that it was often the case that Earth-crew communications were carried out via a huge dish antenna located somewhere other than in the continental US (I believe one such station was located in Woomera Australia) it is all the more amazing. Analog transmissions, over thousands of terrestrial miles. With so little hum.

This was more than a decade before NASA's TDRSS (digital) satellite system was put in orbit.

Badass!

PLEASE put this on display.

I'd love to see it.

At one time, man decided to see just how far their reach could extend. And they stepped on the moon.

Seeing the tail nozzle of the SAT V at the Smithsonian, or walking under the entire intact rocket at the Kennedy Space center fills me with awe.

Those were the days when America had “The Right Stuff.”
