After the additional dredging of 39,000 cubic yards of mud to free the hull and propellers, the USS Intrepid finally escaped its Hudson River pier on Tuesday. The first attempt to move the 36,000 tons of aircraft carrier failed a month ago. This time around it got stuck at the same point, but some clever tugboat maneuvering freed it for its journey to dry dock in New Jersey. The Intrepid is scheduled to return to Pier 86 in November 2008.
