Space Shuttle Endeavour's Epic 12-Mile LA Crawl Took 68 Hours

In 2012, retired space shuttle Endeavour made a breathtaking final journey through Los Angeles streets, creeping just 2 mph as crews trimmed 400 trees and removed 220 traffic signals to squeeze its 78-foot wingspan through the city.

The 12-mile trip took three days and became an unforgettable community celebration of space exploration history.
