Hundreds of curious boaters watch as Coast Guard and other law enforcement agencies escort a NASA training shuttle to the Nassau Bay Hilton Hotel dock in League City, June 1, 2012. Crew members from multiple Coast Guard units and the Coast Guard Auxiliary helped guide the shuttle safely through the tight ship channel and under the Kemah bridge, as it made its way to the Johnson Space Center.
