NASA’s inspector general is still gunning for Hanger One. Essentially, the IG and NASA HQ are upset with Ames Research Center’s leasing of property to private groups such as Singularity University, Airship Ventures, and the Google Triumvirate, and insist that future leases correspond to “current or future mission[s]”, and to sell any properties that can’t be leased. I believe the IG is referring in particular to the airfield itself.
Not having any particular knowledge beyond what I find in the local papers, but that seems a bit strange. I thought NASA Ames was one of the centers that was researching heavy lift airships for cargo transport to remote areas, and that Hanger One was intended to be used for these airships.
