Dave Scott's ring-bound Lunar Module Contingency Checklist used on the lunar surface for three days during Apollo 15, measuring 6 x 8, containing 172 pages (86 double-sided sheets, including 7 red "Emergency" pages and 13 blank pages) inside two heavier cardstock covers, signed and flight-certified on the front cover in blue felt tip, "Flown to the lunar surface during Apollo 15, July 26-Aug 7, 1971, Dave Scott, Apollo 15 CDR." The book is identified on the cover as "Part No. SKB32100116-362, S/N 1001," and contains sections for "30-Minute Activation," "Modular Activation," "Docked Deactivation," "Charts," "Special Procedures," "Contingency EVT/IVT," "Emergency," and "Real Time Checklist." The edges of this LM Contingency Checklist are hand-marked "CONT" to facilitate easy access by the crew; a few pages within are also annotated by hand. In fine condition.
Accompanied by a signed letter of provenance from Dave Scott, in part: "I hereby certify that the 'LM Contingency Checklist' included with this letter was used on the lunar surface for three days during the first extended scientific exploration of the Moon at the Hadley Apennine region during Apollo 15…Contents include the rapid LM Activation (30 Minute) and the Docked DPS burn (lifeboat maneuver) both of which were used successfully during Apollo 13. Major sections include charts, graphs, circuit breaker diagrams, computer procedures, and LM systems emergency procedures. For quick access, each section could be located by one of the many page tabs…Although the major objectives of the Apollo Program were to land men on the moon, explore the lunar surface, and return the crew safely to earth, the safety of the flight crew was of paramount importance. The stringent requirement for crew safety dictated the necessity of as much or more contingency planning than is provided for the nominal mission. Such contingency planning and procedures are accomplished by an adequate crew warning technique and a method of escape. Crew warning was provided by cockpit indicators and Mission Control; and Contingency Procedures as presented in this Checklist were defined to ensure a method of escape is available quickly."
