FLOWN APOLLO 11 FLIGHT PLAN SHEETEXTENSIVE ANNOTATIONS.
Apollo 11 Flight Plan, pp 3-107/3-108, a single sheet printed recto and verso, NASA/MSC, July 1, 1969, 10½ by 8 inches, extensively annotated by Armstrong and Aldrin, inscribed later by Aldrin on each side.
One of the longest and most detailed set of notes made by Armstrong and Aldrin during the entire Apollo 11 flight. Accompanied by a Typed Letter Signed by Aldrin, which reads in part: "Enclosed with this letter is a sheet numbered 3-107 and 3-108 from the Apollo 11 Flight Plan, Part No. SKB32100080-350, S/N 1001. It is part of the entire document that was carried to the Moon in Command Module Columbia on the first lunar landing mission during July 16 to 24, 1969. This sheet is from the detailed timeline section and covers from hour 146 to the beginning of hour 150 in the mission.
The previous day, July 21, Neil and I had left the lunar surface after an approximately 22 hour stay and a 2 hour surface excursion. Once we completed rendezvous, we started preparations to return home to earth. Our Transearth Injection (TEI) engine burn had to work. If it did not, Neil Armstrong, Michael Collins, and myself would remain in lunar orbit, never to return.
The TEI burn did work and we were able to get several hours rest afterwards. At about 147 hours into the mission, Mission Control gave us a wake-up call. After the post sleep activities, we prepared for and made the MCC5 (Mid Course Correction) burn number 5 to refine our trajectory back to earth. On side 3-107, I recorded the hours of sleep for each of us with: 'CDR - 8, CMP - 8, LMP - 8.5' plus checked-off six steps of the Post Sleep Checklist. I then made all eight entries in the Consumable Update box and made four other check marks. I logged the H2 Purge occurring '@ 32' minutes into hour 147 and wrote 'charge Bat A UFN' (Until Further Notice) along the bottom of the sheet.
Side 3-108 lists steps just prior to the MCC5 burn. Commander Neil Armstrong checked-off the first 3 steps on this side and made a large check mark next to the IMU (Inertial Measurement Unit) P(rogram) 52 realignment step. At the right side, Neil recorded the following values in the P52 (PTC REFSMMAT) data block of: '14, 16' for N(oun) 71, '000.01' for N(oun) 05, and the X, Y, Z components of N(oun) 93 of '+00.265, +00.268, +00.012' at a GET (Ground Elapsed Time) of '149:19:30' in hours, minutes, and seconds. PTC stands for Passive Thermal Control and REFSMMAT stands for Reference Stable Member Matrix. I then recorded the last comments of: 'Waste H20 to 10%' and 'MCC 5 1/5 nom time' meaning the burn would be about 5 feet per second at the nominal time."
The sheet is inscribed on both sides by Aldrin: on one side "Flown to the Moon, Buzz Aldrin," and on the other "Carried to the Moon on Apollo XI, Buzz Aldrin." A copy of the flight plan cover is included.
