Apollo 13 pre-launch mission memo, one page, 8 x 10.5, dated March 31, 1970, bearing printed signatures of Rocco A. Petrone and Dale D. Myers, providing a brief overview of the planned Apollo 13 mission, including objectives and extravehicular activities all the way to splashdown. Memo is stapled to the front cover of a 46-page Apollo 13 Mission Operation report, including the experiments, moonwalks, and other activities during the 10-day mission. As a result of the malfunction, the whole operating plan was thrown out the window as the moon mission soon became a rescue mission. RRAuction COA.
