The Tribune photo, dated March 28,1984, has the following caption on the back: "Spectators look over aerobatic planes as the show." [Note: the date on the Tribune caption is almost three years later than the date given by the photgrapher.] Four single-engine airplanes are lined up side by side behind a rope barricade at the Livermore Air Show. All but the farthest back have distinctive, geometric paint schemes on their wings. The one next to it, i.e third from the near end, has the words "Hot Dam" on its rudder.
