“The Washington skyline is due for an exhilarating lift in three years or so, when a spectacular memorial honoring men and women of the U.S. Air Force rises on a hill just west of the Pentagon. Unveiled yesterday, the memorial design by architect James Ingo Freed appropriately is a soaring thing, an airy triumvirate of stainless steel pylons ascending in gentle arcs into the Virginia sky. The highest of the spires will ascend 270 feet above a granite-paved plateau on a promontory overlooking the Pentagon and monumental Washington. A second arc comes in at 230 feet, and the third tops off at just above 200.”
