The Goodyear Airdock in Akron, Ohio was built in 1929 for one specific purpose, giving America's rubber capital a building massive enough to construct entire airships indoors. Designed by the Wilbur Watson Engineering Company of Cleveland and built by the Goodyear Zeppelin Corporation, construction started on April 20, 1929, and the whole structure was finished in just seven months, on November 25, 1929, at a cost of roughly 2.2 million dollars.
The scale of it is genuinely hard to picture without seeing it. The Airdock stretches 1,175 feet long, 325 feet wide, and rises 211 feet high, with 364,000 square feet of completely unobstructed floor space, enough room to fit nearly seven football fields inside. At the time of its completion, it was the largest building in the world with no interior supports at all, an engineering feat that let the whole cavernous space stay open enough to build airships that stretched hundreds of feet long. Its unusual half-cylinder shape has been described as looking like half a silkworm's cocoon sliced lengthwise, giving it one of the most distinctive silhouettes of any industrial building in the country.
That massive interior volume created some genuinely bizarre side effects. The space was so large that clouds occasionally formed near the ceiling, and workers reported it sometimes rained lightly inside the building, an actual documented weather phenomenon happening entirely indoors. Engineers even had to build the structure on rollers so it could physically expand and contract with seasonal temperature changes without cracking apart.
The Airdock earned its place in aviation history almost immediately, hosting the construction of two massive Navy airships, the USS Akron and its sister ship USS Macon, launched in 1931 and 1934. Both were part of an ambitious era when airships were genuinely expected to become the future of long distance air travel, complete with mooring towers planned for major cities and glossy advertising promising luxurious sky travel aboard rigid dirigibles. The last blimp actually built inside the Airdock was the Navy's ZPG-3W, completed in 1960, closing out roughly three decades of Akron building some of the largest flying machines ever constructed.
Ownership has changed hands several times since Goodyear's aviation era wound down, passing to the Loral Corporation in 1987 and then to Lockheed Martin in 1996, which still owns the building today and reportedly conducts confidential aircraft research inside it. Goodyear itself still keeps its famous blimp fleet nearby at Wingfoot Lake in Suffield, but the Airdock remains the structure most associated with Akron's identity, a genuinely enormous piece of aviation history that longtime residents drive past so often they sometimes forget just how extraordinary it actually is.
