The SR-71 was a product of the genius of Kelly Johnson and his “Skunk Works”. It was designed in pretty much in the pre-computer days with slide rules and solid engineering. Ditto for the Saturn V moon rocket.

Ditto that on Saturn V. As noted long ago that Saturn V was a beast, generating 160,000,000 horsepower at lift-off. The turbo pumps feeding those 1st stage F1s were rated at 55,000 horsepower. They fed 15 tons of propellants per second to the five F1 engines, 30,000 pounds per second. They provided seven and one half million pounds of thrust. They got it going about 5,000 mph before the second stage J-2s kicked in. It just seems so incredible that we put twelve men on the moon and they all came home. Staggering!
