Weeksville Blimp Hangar #2

This 2002 Brian Hawley photo is incredible – note how the two trucks are dwarfed by the structure.

More photos and an excellent write-up on the hangar (and its wooden counterpart which burned down in 1995) can be found by following the above link to the NE North Carolina page of Abandoned & Little-Known Airfields.

Update: It looks like TCOM, an airship and aerostat manufacturer, is using this structure as its Elizabeth City Manufacturing and Flight Test Facility.  It can house six fully-inflated aerostats and includes a clean room for dust- and pollutant-free fabrication.
