Original flown printed flight plan page carried on board Apollo 11, one page both sides, identified as pages 3-89 and 3-90, 10.5 x 8, signed and flight-certified along the bottom of page 3-90 in blue ballpoint, “This page was flown to the Moon aboard Apollo XI, July 1969, Buzz Aldrin.” The page came from the detailed timeline section of the Apollo 11 Final Flight Plan manual carried into lunar orbit on the CM Columbia and outlines hours 123 through 125, covering the launch preparations and actual liftoff of Lunar Module Eagle from the lunar surface. Especially interesting are diagrams in the right column, which depict the Eagle lifting off from the lunar surface and the Command Service Module orbiting the moon as the two prepare for rendezvous and return to Earth. In very fine condition. Includes a letter of provenance signed by Aldrin, one page, 8.5 x 11, personal Apollo 11 letterhead, February 24, 2004, stating that the page “is part of the entire document that was carried to the Moon in Command Module Columbia during the first lunar landing mission…Neil Armstrong and I depended on successful firing of the LM’s ascent stage engine, otherwise we would have been stranded on the lunar surface. Mike Collins had no rescue capability with Columbia if we did not lift-off from ‘Tranquility Base.’ 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.” One of very few to outline scheduled actions during lunar surface activities, this is doubtlessly one of the most important and desirable pages from the Apollo 11 Final Flight Plan.
