Guenter Wendt’s Mercury-Atlas Emergency Procedures For Pad Area Rescue manual, dated inside “4/15/63,” for “Mercury–Atlas Spacecraft 20,” which was Gordon Cooper’s Faith 7 mission, the final mission of Project Mercury. The manual, bound together by three zip ties, measures 5.75 x 8 and contains 80 pages of information and procedures for different emergencies and scenarios. Manual is signed inside on the title page, “Guenter F. Wendt,” with his name also printed in another hand on the front cover. Manual covers the times from T–135, through lift-off, up to after T+10 seconds. Broken into five separate sections, failure types listed include Launch Vehicle Fire, Escape Rocket Ignition, Internal Spacecraft Fire, Uncontrollable Loss or Rise in Launch Vehicle Pressure, Aeromedical or Communicator Emergency Removal Request, and Escape Rocket Inadvertent Ignition. In very good condition, with a few loose pages, scattered toning and soiling, and expected handling wear. A very vital, but thankfully unnecessary, relic from the early days of manned space travel.
