One of the country’s tallest launch vehicles took off with a roar that could be heard for miles along the California Coast. The Delta Four Heavy Rocket carried a top-secret defense satellite into space yesterday morning from Vandenberg Air Force Base near Santa Barbara. The launch was a joint effort between Lockheed Martin and The Boeing Company, and it was the second time a Delta Four Heavy rocket took off from the West Coast. The 235-foot tall rocket is the nation’s tallest rocket in regular service. The Saturn Five is the tallest rocket at 363-feet tall.
