Big buildings are not unusual in Ohio, but Akron has a structure that makes "big" a bit of an understatement. In fact, when it was built, the Goodyear Airdock was the biggest building, without interior supports, in the world. It's vast. At its farthest points, it's 1,175 feet long, 325 feet wide, and 211 feet high. You could fit eight football fields inside with room to spare. The structure is so big that a legend developed about rain falling inside it. That's exaggerated, though. In high humidity, the interior gets misty, but it hasn't actually rained.

The Goodyear Airdock was built for the Goodyear Zeppelin Corporation in 1929, at a cost of $2,200,000. Why so big? It was made for building airships, large, lighter-than-air craft, such as dirigibles and blimps. At the time, a lot of people believed that airships were the future of travel and military strategy. The burning of the Hindenburg and structural problems in vessels that used non-explosive fuels put quite a crimp on the idea.

To accommodate the enormous dirigibles, the ends of the building incorporate huge semi-spherical doors fastened at the top by six-foot long pins. The doors are set on wheels that open them by rolling on a track.

In its days as a construction site for airships, the airdock produced many vessels, including two US Navy craft, the USS Akron and the USS Macon. Even with a very much reduced demand for airships, their construction at the airdock didn't end until 1960. In later years, the facility was home to the photographic division of Goodyear Aerospace Company. It is currently owned by Lockheed Martin.

By the way, do you notice the silver squares about halfway up the building, in the picture? They're the windows. It will give you a sense of how big the place is when I tell you they're a hundred feet off the ground.
