Leaving Reagan National Airport (DCA) yesterday, clear skies afforded a view of the Pentagon, which a comment on NPR this evening reminded me is the only building struck on September 11 and still standing. Living in Little Rock, Arkansas, in 2001, I remember many of us who had occasional business in the nation's capital thought that DCA surely would have to close. A shame, we thought, given its convenient proximity to district destinations. No doubt a result of hard work by federal officials, along with some blessings and some luck, DCA operates still. And that, business as usual, seems to me, is the best evidence of a society prevailing over terrorism. Photo by RJ Peltz-Steele CC BY-NC-SA 4.0.
