It looks like an upside-down bathtub with wings, pretty odd for a spy jet that was among the nation’s most highly classified pieces of military hardware. As I stand in front of the plane code-named Tacit Blue at the National Museum of the U.S. Air Force, near Dayton, Ohio, I’m reminded that it still holds a bit of mystery.
