Available to US bidders only. Green angled shuttle fit check tile, used on the Challenger, 8.5 x 7.5 x 2.5, marked “V070-391044-062,” and “OV-099 Only,” with technician’s notations on the other side. Tile comes with a wooden display stand with an informational plaque affixed to the front. Before crews installed the actual reentry-enabling thermal heat shield, fit-check tiles were fabricated and installed on the orbiter's body. These ‘stand-in’ tiles were then referenced to manufacture their flight-ready counterparts. In very good condition, with several edge and surface chips, and scattered paint loss. RR Auction COA.
