FLOWN APOLLO 11 FLIGHT PLAN SHEETTHE LAST DETAILED NOTES BY NEIL ARMSTRONG DURING THE MISSION.
Apollo 11 Flight Plan, pp 3-132/3-133, a single sheet printed recto and verso. NASA/MSC, July 1, 1969. 10½ by 8 inches. Extensively annotated by Neil Armstrong on each side. With a Typed Letter Signed by Aldrin.
BUZZ ALDRIN'S letter reads: "Enclosed with this letter is a sheet numbered 3-132 and 3-133 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 192 to the beginning of hour 194 in the mission.
Side 3-132 lists the steps Neil Armstrong, Michael Collins, and I performed during our last day in space. We were a bit busy getting ready for re-entry. Our entry trajectory was so precise that plans for the MCC7 (Mid Course Correction) burn number 7 were not done. Neil made three 'X' marks over the MCC7 burn and related steps since that burn was canceled. Neil then made two very large 'X' marks over the P23 and Burn Status Report blocks. He also checked-off the last two steps on side 3-132.
Side 3-133 lists seven additional steps to prepare for re-entry. Again Neil checked-off or marked through each step once completed and wrote 'O.K.' next to the SXT (Sextant) Star Check step. We then made our final realignment of the mission by performing a P(rogram) 52 with our IMU or Inertial Measurement Unit. Along the right side, Neil recorded the following values in the P52 (ENTRY REFSMMAT) data block of: '01, 45' for N(oun) 71, '000.01' for N(oun) 05, and the X, Y, Z components of N(oun) 93 of '+00.016, -00.040, -00.010' at a GET (Ground Elapsed Time) of '+193:35:25' in hours, minutes, and seconds. REFSMMAT stands for Reference Stable Member Matrix.
Although Neil, Mike, and I were very busy during the period outlined on this sheet, we did have a chance to reflect on the accomplishments of the past few days - making the first lunar landing, the first lunar surface excursion, lift-off from the Moon, the lunar orbit rendezvous, and the return voyage back to earth. We would soon be making a splashdown in the Pacific Ocean on this last day of the first lunar landing mission, July 24, 1969.
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 side 3-132: 'Carried to the Moon on Apollo XI' and signed it near the center. I have also written: 'Flown to the Moon' and signed my name along the left side of 3-133." A copy of the flight plan cover is included.
