Flown thermal barrier carried on board the Space Shuttle Atlantis during mission STS-86 from September 25, 1997 to October 6,1997. Barrier approximately measures 13.5″ in diameter and was installed at the orbiter's mold line (OML). Barriers such as this one utilized an inner tubular spring made from inconel wire and helped insure the orbiter's frame did not exceed 350 degrees while in space. The barrier was removed from the Atlantis in March 1998, after a post-flight inspection showed this example to be damaged and scheduled to be scrapped.
