Perhaps the most chilling detail of what happened yesterday morning in Joaquin V. Gonzalez, a town of 20,000 residents considered by traditionalists as the "heart of the province of Salta" is the abundance of eyewitness accounts and the manner in which they are so perfectly synchronized with each other. This little town is also known to the ever-watchful gaze of science for the fact that its heights are regularly swept by the passing of UFOs.
