Comprehensive handwritten timeline for the launch phase of Apollo 16, six gridded pages, 8.5 x 11, written by Kranz in felt tip and colored pencil. The pages are arranged in three sets, labeled “1A,” “1B,” “2A,” “2B,” “3A,” “3B,” with the first two sets headed “Launch Phase Timeline—Apollo 16,” intricately filled out by Kranz with important details of the launch. The first set outlines abort scenarios for the four stages, with a note at the top: “General: LV ATT REF. fail will cause CSM Guidance takeover. LV Accelerometer fail will cause F/M profile in AMS.” The second set of pages is the timeline of launch phases, beginning with “Liftoff,” noting certain expected times and parameters. Among the items listed are: “Go/No Go Staging,” “2:41 SII Eng Start,” “3:20 Guidance Initiate,” “6:55 S-IVB to Orbit,” “Go/No Go—Orbit,” and “Insertion Status.” The third pair of pages continues the phase timeline but is sparsely filled out compared to the others, with notes such as “Gimbal Motors—Off,” “S-IV Orbital Status,” and “Contingency Separation.” In fine condition, with tears to binder holes along the edges and light expected wear from use. Accompanied by a signed letter of authenticity from Kranz, in part: “My hand written Apollo 16 Launch Phase Timeline that accompanies this letter comes from my personal files.” The Apollo 16 launch performed as expected until encountering minor technical issues once in Earth orbit, including a potential problem with the environmental control system and the S-IVB third stage's attitude control system—these however were quickly resolved. Kranz’s attention to detail and the readiness of Mission Control in preparing for all possibilities during spaceflight are readily apparent in these impeccably detailed pages.
