[HAISE, FRED, AND JAMES LOVELL.] "DEDA Input/Output Constants," single data training card printed on both sides, from the Guidance and Navigation Dictionary for Lunar Module 7, NASA/MSC January 5, 1970, updated February 13, 1970. Light wear to tab.
SIGNED BY APOLLO 13 CREW MEMBERS FRED HAISE AND JIM LOVELL, Haise had additional inscribed, "Used in training for Apollo 13." This page comes from the manual for the LM-7 (Aquarius). Thankfully, Haise and Lovell had trained well and returned safely even after one of the oxygen tanks exploded when they were about 200,000 miles from Earth.
