The Air Force Memorial in Arlington, Virginia, was dedicated on October 14, 2006. I've been meaning to shoot it for a while now, but never found the time until recently. It's a beautiful memorial. It was designed by James Ingo Freed, the architect who is known for designing the United States Holocaust Memorial Museum. Wikipedia nicely describes the design of the Air Force Memorial as follows:

The three memorial spires range from 201 feet (61 m) to 270 feet (82 m) high and appear to be soaring; its array of stainless steel arcs against the sky evoke the image of "contrails of the Air Force Thunderbirds as they peel back in a precision 'bomb burst' maneuver." Only three of the four contrails are depicted, at 120 degrees from each other, as the absent fourth suggests the missing man formation traditionally used at Air Force funeral fly-overs.
