Pretty cool!

It answered a question I'd never got round to asking: why is the first three or four metres of engine exhaust dark like that?

He answered it: it's the cooler turbopump exhaust vented around the nozzle periphery to help cool and protect it from the inferno within. Now I know!

The engineering that went into that program was just incredible. Thanks for sharing this!

I did see the video,... but I saw the Saturn V engines at the Smithsonian Air and Space museum in Washington DC. I highly recommend seeing it.

It was basically 1/4 of the engines with mirrors to represent the others.

I believe they actually used the fuel (Liquid Oxygen) prior to getting pump to the engines as the coolant around the nozzles, to keep the nozzles from burning up.

It never made it to Pluto, though.

Location and nationality are not necessarily the same.
