Flown checklist headed “Landing” carried on the Apollo 12 mission, 6.5 x 9.25, bearing several in-flight handwritten notations denoting times of actual event execution, referenced to elapsed total mission time, including a note by Alan Bean, “Start Camera.” The checklist details sequential activities associated with the last phase of the Command Module’s descent into the Earth's atmosphere and subsequent splashdown. Several strips of Velcro are affixed to the reverse so that it could be attached to the spacecraft’s instrument panel. Some brushing to the numbers written in the bottom chart and a few small stains at the bottom, otherwise fine condition. Accompanied by a letter of provenance signed by Richard Gordon and Alan Bean, in full: “Abbreviated Apollo 12 Instrument Panel Checklist used by the LMP during Lunar Return Reentry.” The checklist calls out the key elements of Earth Landing System activation and deployment in primary and backup contingency modes, listing the procedures at specified altitudes marked along the left edge. It begins at 90,000 feet above the Earth's surface as the Command Module is preparing to jettison its forward heat shield so it can expose and deploy the drogue, followed by the main parachutes, to slow the spacecraft as it prepares for splashdown. Post-landing procedures are also detailed, including activation of the uprighting system. As a checklist with in-flight notations used during a critical segment of the mission, this is a particularly desirable flown item. The Leon Ford Collection.
