The space shuttle Endeavour is finally on the home stretch of its journey through the streets of Los Angeles to its retirement home at a museum.
The space craft was originally expected to arrive at the California Science Museum on Saturday evening, but it faced repeated delays throughout the day.
The Endeavour was towed out of Los Angeles International Airport early on Friday and by Saturday morning it was 90 minutes ahead of schedule. But accumulated delays caused it to run hours behind at the end of the day.
The problems included longer than expected maintenance of the rig carrying the shuttle and physical obstacles within the shuttle's wingspan including light posts, building edges and trees.
The thousands of people watching along the streets remained peaceful. Police said they hadn't made any arrests.
