FLOWN APOLLO 11 FLIGHT PLAN SHEETARMSTRONG VERIFIES EAGLE'S STATUS.
Apollo 11 flight plan, pp 3-64/3-64a, a single sheet printed recto and verso, NASA/MSC, July 1, 1969, 10 ½ by 8 inches, inscribed in ink by Buzz Aldrin.
Accompanied by a Typed Letter Signed by Buzz Aldrin, which begins similarly to that in the preceding two lots, and continues: "Side 3-64 has three columns of tasks listed for the CMP (Mike Collins), CDR (Neil Armstrong), and myself the LMP. At this time, both Neil and I were inside the LM checking out various systems. After an antenna check, I went back into Columbia and donned my pressure suit, then returned to Eagle. In just about 3 hours from this point, Neil and I would undock from Columbia and Mike Collins to being Man's first landing on another world - THE MOON!
Side 3-64a has a drawing of several attitudes Columbia and Lunar Module Eagle were to maneuver to while in lunar orbit ... Due to the fact that the lunar gravity force is influenced by an uneven distribution of the Moon's mass about its center, obtaining a circular lunar orbit was difficult to achieve. To improve upon our preflight gravitational model, Mike took these series of landmark tracking measurements with our sextant which provided relative positions of our orbit and the planned landing site. Any updates based on these measurements could be incorporated to insure that Eagle could reach the planned landing site within the LM's propulsive capabilities.
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."
The letter also states that this sheet has been in Aldrin's collection since 1969. He has inscribed on page 3-64a below the lunar orbital diagram: "Carried to the Moon on Apollo XI, Buzz Aldrin." A copy of the flight plan cover is included.
