Never happened. Total BS. Prove it.
Burned 12 1/2 tons of fuel per second, mind-boggling. On a DVD around here somewhere, a few of the Apollo veterans were describing the sensation after liftoff, that the craft was gimballing to keep the whole works balanced as it pushed it up off the ground. It had a “nervous” quality one of them said. The F1 never had a launch failure, but one of these astronauts mentioned that, if one engine had quit in the first 15 seconds, the whole works would have come down — after that point enough mass of fuel had been burned that the four remaining engines would have accomplished the needed burn, taking a bit longer to do it.
Yes, an impressive piece of machinery. I remember Anders speaking of the very thing you mention. The outer F-1s could move. The rocket would not fight the wind, it would adjust its course by gimballing. Anders said it was like being atop a car antennae when it was whipping about.
Another impressive thing was the guidance and navigation.
Robert Zimmerman:
“The spacecraft had left a planet whose surface was moving at about 1,000 mph as the globe rotated. That planet was also cruising through space at 67,000 mph. The spacecraft was aimed at a moon moving at 2,300 mph relative to the earth, with an orbital plane that differed from the spacecraft’s. Each of these vectors had to be incorporated into Lovell’s and the ground engineers’ calculations so that they could aim Apollo 8 not at where the moon was, but at a point in space it would reach three days hence. And their calculations had to be accurate within four ten-thousandth of a single percentage point.
This was not unlike a person jumping from a speeding roller coaster and trying to catch a bullet shot past them as they fell.”
NASA's Apollo program managed it nine times. Rest of world, still zero.
Yes, one of the most amazing things ever. Twelve men have walked on the moon, all Americans. I’m proud of that. Also proud to have paid taxes for the program and especially proud of the 400,000 people who worked on the project.
You're American, yes? And you don't believe one of the most significant events in your nation's history didn't happen?
Why?

Why?
“I wear a NASA t-shirt regularly when I am walking - it always gets comments and smiles from the boomers; we were so lucky, we had real heroes, no computers, no I phones and no internet. They were glorious times.”
Yeah,and you had Viet Nam,riots, and assassinations.
Glorious times indeed.
