LOS ANGELES (AP) — It was supposed to be a slow but smooth journey to retirement, a parade through city streets for a shuttle that logged millions of miles in space.

But Endeavour's final mission turned out to be a logistical headache that delayed its arrival to its museum resting place by about 17 hours.

After a 12-mile weave past trees and utility poles that included thousands of adoring onlookers, flashing cameras and even the filming of a TV commercial, Endeavour arrived at the California Science Center Sunday to a greeting party of city leaders and other dignitaries that had expected it many hours earlier.
