The information that Haise supplied about the card reads:
"This cue card was carried around the moon on the flight of Apollo 13 during April 11 to 17, 1971. This card was positioned on the instrument panel with Velcro during the launch to be used in the event of a Mode III abort. This abort mode became available in the period of launch just before achieving the Abort-to-Orbit capability. On the cards are blanks to be filled in for a manually executed SPS retrograde maneuver such as Time Of Ignition (TIG), Burn Time (BT), Pitch attitude, Ground Elapsed Time (GET) to reach 300k feet altitude, Pitch attitude reaching .05G, and the time for Drogue parachute deployment. The burn was to change velocity by 6999.9 feet per second to assure an Atlantic splashdown short of the African continent. We did not have to use this card but did have to deal with a much more complicated abort case on Apollo 13."
