As an Airman, it was a special treat to visit my own service's memorial overlooking the Pentagon and grander DC skyline. Finished in 2006, the memorial was built in the path of American Airlines Flight 77 which crashed into the Pentagon on September 11, 2001, so when you stand in the main platform area, you can see how the plane veered down to the building. The memorial commemorates Air Force Core Values, Medal of Honor Recipients and more. I got the impression of an aerial runway and ramps based on the concrete layout, but I could be wrong. The three burnished metal pylons fired skyward and reflected the early afternoon sunlight. It was a quiet and simple way to honor our nation's history of air service.
