Three men (look closely) stand inside Arnold Engineering Development Complex's 16-foot supersonic wind tunnel facility. The tunnel, seen here in 1960, is housed at Arnold Air Force Base, Tennessee, but is now inactive.

The wind tunnel was capable of Mach numbers between 1.60 and 4.75 through a test section 4.8 meters wide and 20.2 meters long. It served as a large-scale testing facility for aircraft and propulsion systems. Like many large-scale and high-speed wind tunnel facilities in the United States, it is no longer active. In recent years, many unique wind tunnel facilities at NASA, military bases, and universities have been closed down, depriving researchers and engineers of the ability to include large-scale testing in their design and development of new technologies.

CLANK! CLANK! CLANK!

Night gathers, and now my watch begins. It shall not end until my death. I shall take no wife, hold no lands, father no children. I shall wear no crowns and win no glory. I shall live and die at my post. I am the sword in the darkness.

CLANK! CLANK! CLANK!

I am the watcher on the walls. I am the shield that guards the realms of men. I pledge my life and honor to the Night's Watch, for this night and all the nights to come.

CLANK! CLANK! GRRRRWRRR!
