Project Offices

A Project Office located in Chatham County, North Carolina, colloquially known as "Big Hole", came online in the mid-1960s and was described by area residents and persons employed in the construction of the site as being "department-store sized" with walls "several feet thick" covered in copper, buried 30 feet (9.1 m) underground on large shock-absorbing springs, constructed with plumbing made out of rubber, and outfitted with tropospheric scatter antennas.

[1] The Big Hole Project Office was located on 191 acres of company-owned land surrounded with fencing, CCTV cameras, and steel crash barriers.

[1] Big Hole may have been shuttered in 2008; media noted at the time that several convoys of trucks appeared to have moved large amounts of equipment out of the site over the course of several weeks and a company guard force had been withdrawn.

The corporation "abruptly abandoned" Project Aurelia after local government officials proposed a public hearing on the construction to address environmental concerns.

[3][4] Due to the private nature of Project Office business activities, wild claims and urban legends have sometimes accompanied description of the sites.
