Endeavour's farewell tour

A detail of the tiles on the underside of Space Shuttle Endeavour as it arrives at the Forum en route to the California Science Center on October 13, 2012 in Inglewood, California. Endeavour is on its last mission - a 12-mile creep through city streets, past an eclectic mix of strip malls, mom-and-pop shops, tidy lawns and faded apartment buildings.
