Scarce pair of Evaluation Stowage Straps used to determine the best position for the flight Apollo 11 Portable Life Support System (PLSS) harnesses. Both straps are constructed of durable off-white Beta cloth, with one measuring 12.25 x .5, and the other 11.5 x .5, with both featuring male and female snaps at opposite ends; the longer strap is marked in black felt tip, “S/N LL3 SVSK 7070,” and the other is marked: “S/N LRZ SVSK 7070.” The stowage straps were designed to hold the left and right upper and lower harnesses in their stowed configuration. Without the harness stowage straps, the four PLSS harnesses would hang freely with the risk of getting tangled. Apollo 11 astronauts Neil Armstrong and Buzz Aldrin had significant input in the final configuration of the stowage straps. In overall fine condition. From the collection of Dan Schaiewitz, who worked as Extravehicular Crew Training Engineer at KSC.
