Hangar One once held 1930s-era dirigibles, including the U.S.S. Macon. You could fit three Titanics in there, side by side, a NASA historic preservation officer once told Air & Space magazine. And now, Google is taking over the lease for the airfield where Hangar One sits, and plans to restore the historic building, too.

We've wondered before what would happen to Hangar One. NASA was responsible for it, and for Moffett Federal Airfield, but the hangar required expensive renovations to make it safe for people and the environment. As the structure aged, its siding began leaking toxins into the San Francisco Bay. The U.S. Navy, which agreed to take responsibility for the toxic siding, once considered tearing the whole thing down.
