English: Space Shuttle Explorer on display at Kennedy Space Center Visitor Complex in Florida. This is a full-scale replica of a Space Shuttle, so it has never flown. Internal details of the mock-up are not remarkably accurate, though the size and scope of the payload bay is correct. Externally, the mock-up features simulated thermal protection system tiles (bearing numbers, as the genuine flight articles do), paneling that looks like reinforced carbon-carbon panels on the leading edges of the wings, and Michelin tires on the landing gear.
