airships. The last airship built in the airdock was the U.S. Navy's ZPG-3W in 1960. The building later housed the photographic division of the Goodyear Aerospace Corporation. In 1980, the Goodyear Airdock was designated a Historic Civil Engineering Landmark by the American Society of Civil Engineers. The airdock has more recently served as the site of the 1986 kickoff rally for the United Way of Summit County, where 200,000 members of the public visited. Bill Clinton spoke there during his 1992 election campaign, bringing some 30,000 visitors to the site. In 1987, the Loral Corporation purchased Goodyear Aerospace and the Goodyear Airdock as a result of James Goldsmith's greenmailing of Goodyear. The Loral Corporation (and its holdings, including the Goodyear Airdock) was purchased by Lockheed Martin in 1996. California company LTA Research and Exploration, together with the University of Akron, plans to use the airdock to develop electric-powered airships. The airdock is not open to the public, but it can be seen by those traveling on U.S. Route 224 east of downtown Akron.
