Deep in the Rio Grande Valley, and all along the South Texas border with Mexico, local residents have been seeing strange objects streaking across the sky for decades. In South Texas UFOs: Chilling Encounters on the Mexican Border, author Noe Torres documents the region's most persistent unexplained cases - a Harlingen family terrorized by a craft and its occupant, a McAllen man abducted and later visited in his own apartment, a UFO that shot fire at eight construction workers in Edinburg who barely escaped with their lives, a UFO that buzzed Brownsville before crashing in Mexico and vanishing into military custody, and dozens more encounters involving lawmen, Border Patrol agents, and aviators. Based on newspaper archives, declassified Air Force files, and firsthand witness testimony, this is South Texas history that officials have never fully explained.
