outside the administration building, it is the only part of the memorial that depicts aircraft. The north inscription wall is visible through it. The two inscription walls are located at each end of the central lawn. The walls are in length, in height and one foot thick. Both walls are made of polished, highly-reflective monolithic Jet Mist granite and both include a two and a half-inch outer inscription panel made from Absolute Black granite. The north wall bears the names of Air Force recipients of the Medal of Honor, and the south wall bears inspirational quotations regarding core values, particularly the Air Force's three core values: "integrity first, service before self, and excellence in all we do". One name has been removed from the Medal of Honor Recipients, under the header of "Peacetime". This name listed was that of Colonel William "Billy" Mitchell, and it was removed due to a clerical error in actual Medal of Honor recipients in a Congressional Report published in 1979. His name was included on the wall at the memorial in error and has since been removed. The removal is quite visible, with the name being cut out of the stone, and a new stone filler in its place above the name of Charles Lindbergh. ″There is some debate as to whether Mitchell was in fact awarded the Medal of Honor or the Congressional Gold Medal. The act cited directs that "a gold medal" be struck and presented in recognition of Mitchell's pioneer service and foresight. It does not, however, specify which medal was to be awarded. In July 1945 the War Department had recommended to Congress that special gold medals be voted by Congress in cases of outstanding leadership and that the Medal of Honor be reserved for awarding only gallantry in action. Major General William "Billy" Mitchell was awarded the Congressional Gold Medal, which was announced using the identical citation and approved date as listed for the award above. It seems apparent that the intention was to award the Gold Medal rather than the Medal of Honor. However, for some unknown reason, when the Senate Committee on Veterans' Affairs published its report, Medal of Honor Recipients: 1863-1978 (Washington, D.C.: Government Printing Office, 1979) compiling all Medal of Honor Recipient citations, William Mitchell and his citation were included. This website takes its Medal of Honor citations from that report, and that is why Mitchell's
