The last space shuttle external tank in existence, headed from the New Orleans manufacturing plant to the California Science Center for the vertical launch pad display of the retired orbiter Endeavour, has passed through the Panama Canal.
Navigating the 48-mile Panama Canal that slices through the isthmus, the final shipment of a space shuttle external fuel tank emerged into the Pacific for a three-week trek to California.
The tugboat and barge transporting the last space shuttle external tank to its display venue in California have reached the inlet to the Panama Canal, now just days away from sailing into the Pacific.
