FLOWN APOLLO 11 FLIGHT PLAN SHEETSOME OF THE FIRST WORDS WRITTEN BY ARMSTRONG IN THE FLIGHT PLAN.
Apollo 11 Flight Plan, pp 3-9/3-9a, a single sheet printed recto and verso. NASA/MSC, July 1, 1969. 10½ by 8 inches. Detailed annotations in pencil by Armstrong and in ink by both Armstrong and Aldrin. With a Typed Letter Signed by Buzz Aldrin.
The Apollo 11 crew was completing their first day in space and securing systems prior to the first rest period. After Neil Armstrong logged the numbers of the P52 data results, he inscribed "Verified on 33" as a reminder that they had checked these results using the star Antares.
ACCOMPANIED BY BUZZ ALDRIN'S LETTER, which reads in part: "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 ... This page has been in my private collection since 1969."
Aldrin has inscribed and signed page 3-9 with "Carried to the Moon on Apollo XI, Buzz Aldrin." A copy of the flight plan cover is enclosed.
