USAF memorial HDR
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
The four bronze statues of the Memorial's Honor GuardThe spire structure consists of stainless steel plates with high-strength concrete filling the lower 2/3rds of each spire. The upper third is hollow stainless steel. At the transition between concrete and hollow steel portions, dampers provide aerodynamic stability and dissipate wind sway energy. Each damper consists of a lead ball weighing about a ton that is allowed to roll inside a steel box. The structural design of the spires was completed by the Arup engineering consultancy.
