On Apollo flights carrying duplicate checklists, was it customary to make in-flight annotations in both? |

Yes. The duplicate checklists such as the Launch Checklist, the LM Activation Checklist and the Entry Checklist were used by two crewmen during those phases of the mission. They wrote their own notations in their copy of the checklist. |

To illustrate what Larry said, here are a couple of pages from the flown A13 LM Systems Activation Checklists - SKB321100082-360 S/N1001 and S/N1002.
Apart from the duplicated pre-flight and in-flight amendments, I am not sure what the protocol was in who used which checklist, but in this example, Fred mostly used checklist 1001 as is shown where he wrote some notes of his own for a TV show just prior to the "problem" and Jim predominately seems to have used checklist 1002. |

Were only some checklists/flight plans used by two astronauts and annotated in-flight? The reason I ask is that there have been pages from flight plans described as flown with places for data or other information to be added in-flight with no in-flight information added. Seems that if that page was flown and used there would be in-flight information on it. |

I think that would depend on a number of things. For instance with the flight plan, say a mid-course correction was not required than there would be nothing to record.And of course, many flight plan pages were just for astronaut information and therefore had nothing to notate on them, and these have been sold with nothing other than maybe the signature of an astronaut or a separate declaration stipulating it came from a flown list. My interest is Apollo 13, which because of its unique situation is probably not a representative example of astronaut plan/checklist usage. However, once again from the Apollo 13 LM Activation Checklist — S/N 1001 on the left used by Fred, S/N 1002 used by Jim on the right — we can see that if pages from checklist 1001 were said to be representative of a flown checklist, then it might raise a question as to its authenticity due to the lack of notations. (Actually, in this case it has other markings on it that would prove its provenance)  In fact, I don't know of any of the "second" copies in the public domain. For instance, sticking with the Apollo 13 LM Activation checklist, other than Jim's copy that was sold in auction some years back, I have never seen any information about the existence of the other flown copy of the activation checklist or for that matter any other copies of the second flown checklist from any mission. No doubt some exist. As an aside, I have never had the opportunity to "handle" a flown Apollo document other than a few training copies that I have and I don't know if the special paper that was used for flight copies was also used for the training copies, which if it were different, might be a way to determine its authenticity. | |
