Apollo 11 Flown Flight Plan Page with Annotations by Neil Armstrong Originally from the Personal Collection of Mis... (Total: 2 Items)
Included with this lot is a signed Letter of Authenticity on Aldrin's personal letterhead. We transcribe it in full because of its detailed explanation of this item's use, as follows:
"Enclosed with this letter is a sheet numbered 3-9 and 3-9a 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 during the first lunar landing mission. This sheet is from the detailed timeline section and covers hour nine to the beginning of eleven in the mission. It has an extensive set of data recorded by Commander Neil Armstrong during the flight.
"Page 3-9 lists a carbon dioxide filter change. Neil Armstrong logged that change taking place at "10:15" into the mission. Neil then recorded our guidance platform realignment program (P52) N71 values of "30, 37," the N05 values of ".01" and the X, Y, Z N93 values of "+01.005, -00.368, 00.737." He logged this alignment occurring at a GET of "009:36:45" (hours, minutes, seconds) into the mission. These were the REFSMMAT or Reference Stable Member Matrix values based on star observations through the sextant. Neil also wrote "Verified on 33" meaning that is realignment was verified using star number 33 which was Antares. I wrote that the oxygen full cell purge was "Deleted @ 11 04" into the mission and lined-out that event.
"Page 3-9a has a table of values associated with Mid Course Correction (MCC) number 1. Our trajectory was precise enough at that point that MCC1 was not required.
"The flight plan was probably the single most important document related to the success of our mission. It provided a time schedule of crew activities and spacecraft maneuvers to accomplish the first lunar landing.
"This page has been in my private collection since 1969. I have written on page 3-9: "Carried to the Moon on Apollo XI" and signed it near the upper part of that page. Additionally, a copy of the flight plan cover is enclosed."
