They very nearly didn't make it in 1969:
The Apollo 11 mission succeeded in landing on the moon despite two computer-related problems that affected the Lunar Module during the powered descent. An uncorrected problem in the rendezvous radar interface stole approximately 13% of the computer's duty cycle, resulting in five program alarms and software restarts. In a less well-known problem, caused by erroneous data, the thrust of the LM's descent engine fluctuated wildly because the throttle control algorithm was only marginally stable.

Armstrong took semi-automatic control and, with Aldrin calling out altitude and velocity data, landed at 20:17:40 UTC on July 20 with about 25 seconds of fuel left.

Twelve men walked on the Moon, only 8 remain. Neil, Pete, Alan, Jim are gone. Buzz, Alan, Ed, Dave, John, Charlie, Gene and Jack live on
A couple of guys went to the moon twice
Apollo 11 nearly went bingo fuel but it was a nice clean mission. They also had bad comms because they did not map the LM for the antenna correctly
Apollo 12 almost aborted on launch due to two lightning strikes that shut off everything except the engines and one guy saved the day. They broke the lunar TV camera by hitting it with a hammer and pointing it at the sun. They also left a bunch of film on the Moon
Apollo 13 well. you know
Apollo 14 CM would not dock with the LM right out of earth orbit and it drove them crazy, nearly costing them the landing. They tried dozens of times slamming into it and finally they got capture. Then everytime they went to test the lunar landing sequence the test would say ABORT BUTTON PRESSED due to a zero G solder glob. They had to drag some software engineer out of bed to get him to write a patch they had to enter one byte at a time. Then the landing radar would not lock up 45,000 feet 30,000 feet, 20,000 they cycled the power to the radar and they just barely got it in time, just barely whisker thin hair raising adventure. CMD Shepard had outright STOLEN the flight from Gordon Cooper
Apollo 15 was the first real good clean mission with the first rover, landing with minutes of fuel remaining. But they got in trouble for post marking stamps on the moon. They broke a fender on the rover. Jim Irwin got so dehydrated he later died young looking for Noah's Ark
Apollo 16 almost aborted on landing due to a CM problem with the main engine. The CMD kicked the cable out of an important instrument on the surface. They too broke a fender. They drove the rover in the Lunar Grand Prix. They tried to see how high they could jump in the Lunar Olympics and one fell over real bad but it was okay
Apollo 17 was pretty sweet but the CMD crashed a helicopter just weeks before launch hot-dogging. The best pictures of launching off the moon. The rover camera was still active for days and they let people play with the remote controls. They took a rookie scientist who fell a lot
There were 3 other missions including a far side landing but they were all canceled. There is a book, "The lost and forgotten missions of Apollo"
I think Apollo 10 could have landed first IF they had used a hybrid non-return trajectory and the CM to insert them into the PDI (Power Decent Initiation) and brought back just a handfull of lunar dust. The lunar lander in Apollo 10 was not fully fueled to save weight since they were going to test abort at 30,000 feet
oh yeah, and Apollo 18 was just a BAD MOVIE

Well said. I remember watching this when I was a kid. Amazing. As active members of the Planetary Society, in my father in laws name (his dream, and our tribute to him), my wife and I can attest there is so much still going on and needing support.
