I do not recall any other mission failures other than Apollo 13. Can you name any specific ones?

I did not read about them in the textbooks. I remember watching them.

Feeling a bit replaced? Do ya?

You don’t remember them burning on the launchpad? Sad stuff.

The original post said several failures AFTER Apollo 1.

Totally missed the original.

11 almost was (several times)

- the computer started throwing error codes on decent that had not been simulated before. they were about to abort when one of the interns happened to know what they were from memory. Apparently as part of a “haze the new guy” ritual was they made this intern memorize all the computer error codes and he was able to give that info in real time.

-they almost had to abort the landing due to fuel. they landed 25 seconds above their abort fuel

- they almost got stuck on the moon. When re entering the lunar module they damaged the circuit breaker that armed the accent rocket. When troubleshooting they figured out the tip of their pen fit in the slot where the breaker was and were able to arm the rocket that way.

How many times does autopilot do strange things, and a pilot kicks it into manual and does a safe maneuver? Sounds like common.

The Apollo 1 crew was less than a success. Apollo 8 was originally supposed to be a test of the LM in Earth orbit, but delays in testing of the LM precluded that, but it was politically decided to launch it into a lunar orbit to beat the Russians in doing so. Apollo 12 was hit by lightning after takeoff, ruining their telemetry until they coukd figure out the problem and switch to an aux system. On the same mission Alan Bean accidentally pointed the TV camera directly at the Sun, frying its circuitry and limiting the lunar videos taken - perhaps one reason that few remember Apollo 12.

It was an engineer who'd worked in the simulator trying to trigger every code/failure they could think of. They triggered 1201/1202 faults and were told to write down every fault code there was. They put a laminated chart of the fault codes under the glass at a console. Second link below has his first hand account of what occurred.

well then I stand corrected. I thought I had read the intern thing in one of the books on the subject.
