LOS ANGELES (AP) - It took much longer than expected, but the Space shuttle Endeavour has finally reached its permanent resting place at a Los Angeles museum.

After a 12-mile journey through city streets 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.

Organizers had planned a slow trip, saying the spacecraft that once orbited at more than 17,000 mph would move at just 2 mph in its final voyage.

But that estimate turned out to be generous, with Endeavour often creeping along at a barely detectable pace when it wasn't at a dead stop due to difficult-to-maneuver obstacles like trees and light posts.
