How NASA brought the monstrous F-1 “moon rocket” engine back to life
There has never been anything like the Saturn V, the launch vehicle that powered the United States past the Soviet Union to a series of manned lunar landings in the late 1960s and early 1970s. The rocket redefined "massive," standing 363 feet (110 meters) in height and producing a ludicrous 7.68 million pounds (34 meganewtons) of thrust from the five monstrous, kerosene-gulping Rocketdyne F-1 rocket engines that made up its first stage.

very interesting
People forget that the solid booster design specs were changed based on requirements of Morris Udal to allow his Utah vendor to bid. Original specs for the solid boosters required a solid single cylinder (hence no joints to fail). Challenger was a result of politics not science!
Lunar landings ...? Where?
Fairly certain the ducting you mention is the injection of cold fuel/oxidizer. The F-1 was a regeneratively cooled engine. This cools the engine cone and pre-heats the fuel before injection. It's apparently a delicate design balance, but Werner knew what he was doing... Wikipedia has a detailed description.

Can anyone identify the purpose of that huge external ducting wrapped around the engine shroud?
