Buzz Aldrin’s CSM-107 Launch Operations Checklist dual-sided page used in the Command Module Apollo Mission Simulator in preparation for the Apollo 11 mission, one page, both sides, 5.5 x 8, signed on the front in blue ballpoint, “Used in training for Apollo XI, Buzz Aldrin.” The front, numbered 2-19, with changed date of June 27, 1969, features the Reaction Control System hot fire test then the beginning of Translunar Injection (TLI) preps at 1 hour 50 minutes, and the reverse, numbered 2-20, has the steps for TLI. Neil Armstrong has made a time change in ballpoint to "36" as well as an angle value to "16," and then in pencil circled the time change and added a question mark. In fine condition.
The checklist page is accompanied by a sheet of personal letterhead signed in blue ballpoint by Aldrin, which reads, in part: “Accompanying this letter is a page numbered 2-19 and 2-20 from the CSM 107 (Apollo 11) Launch Operations Checklist…The pages are part of the complete manual that was used in the Command Module Apollo Mission Simulator at the Manned Spacecraft Center in Houston, Texas. The page is from Section 2 titled: Boost-Insertion—TLI. The entire checklist, including this actual page, was used by all three Apollo 11 crew members: Neil Armstrong, Michael Collins, and myself. This section in particular was extensively used by Neil Armstrong and Michael Collins who sat in the left and center seats during the Saturn V launch phase…I kept this checklist after our mission as a reminder of all the training that took place back in 1969…A copy of the checklist cover page is included.”
